What is the best CAT (Computer-Assisted Translation) tool for a professional translator?

There is no single “best” CAT tool for every professional translator—the best choice depends on your clients, specialization, language pairs, and workflow. However, for a full-time professional translator, these are the leading choices:

SnapIntel SnapIntel## My recommendation by translator profile

1. Freelance translator working with agencies

Best overall: Trados Studio

If your goal is to maximize the number of agencies you can work with, Trados is usually the safest investment. Many agencies still exchange Trados-compatible packages and expect translators to be comfortable with the workflow.

2. Experienced freelance translator who wants the nicest daily workflow

Best choice: memoQ

Many professional translators prefer memoQ because the editor feels efficient, terminology handling is strong, and its QA tools are excellent. It is particularly attractive if you spend many hours every day translating rather than managing projects.

3. Technical, legal, medical, or regulated translation

Top choices: Trados or memoQ

For these fields, terminology consistency and quality assurance matter more than flashy AI features. Both have strong TM and terminology workflows; Trados has the advantage of broad market recognition, while memoQ is often praised for flexibility.

4. Localization (software, apps, websites)

Consider Phrase or another localization-focused platform

Cloud-based systems are often better suited to continuous localization, developer integrations, and team workflows.

If I had to pick only one

For a professional freelance translator starting today:

1. Trados Studio — safest career investment because of client compatibility.
2. memoQ — arguably the best translator experience and excellent professional alternative.
3. Phrase — best if your work is mainly localization teams and cloud workflows.

Many established translators eventually keep both Trados and memoQ, because clients may send projects in different formats and tool preferences vary by agency.

A practical choice would be:

• New freelance translator: learn Trados first.
• Already busy professional: choose the tool your best-paying clients use.
• Specialist translator doing long documents daily: strongly consider memoQ.

If you tell me your language pair(s), specialization (legal/medical/technical/literary/etc.), and whether you work freelance or for an agency, I can narrow this down to one recommendation.

Best choice: memoQ

Many professional translators prefer memoQ because the editor feels efficient, terminology handling is strong, and its QA tools are excellent. It is particularly attractive if you spend many hours every day translating rather than managing projects.

3. Technical, legal, medical, or regulated translation

Top choices: Trados or memoQ

For these fields, terminology consistency and quality assurance matter more than flashy AI features. Both have strong TM and terminology workflows; Trados has the advantage of broad market recognition, while memoQ is often praised for flexibility.

4. Localization (software, apps, websites)

Consider Phrase or another localization-focused platform

Cloud-based systems are often better suited to continuous localization, developer integrations, and team workflows.

If I had to pick only one

For a professional freelance translator starting today:

Because "the best" CAT tool depends heavily on your workflow, operating system, and client base, there is no single universal winner. However, the industry is led by a few heavyweights, each reigning supreme in a different category.

As noted by Version Internationale, “CAT tools have similar features, but some are more translation-focused, while others are comprehensive tools designed to manage the entire localization workflow.”

Top recommendations for professional translators break down by use case:

• Trados Studio (RWS)
  • Best for: Industry-standard compliance and heavy corporate/agency workloads.
  • Why it shines: It is the undisputed market leader. If you work with large Language Service Providers (LSPs), many will explicitly require or expect Trados package compatibility (.sdlxliff). It features robust terminology management, powerful translation memories, and deep customization.
  • The downside: Expensive licensing model and a notoriously steep learning curve; Windows-only natively.
• memoQ Translator Pro
  • Best for: Power users seeking maximum customization and usability.
  • Why it shines: Widely considered the main rival to Trados, memoQ offers a cleaner, more intuitive user interface, superior handling of diverse file formats, and robust QA features. Freelancers love its perpetual license option and seamless interoperability with other tools' packages.
  • The downside: Also Windows-centric (though it runs on Macs via virtualization/Crossover with varying degrees of success).
• Phrase TMS (formerly Memsource)
  • Best for: Cloud-native flexibility and modern localization workflows.
  • Why it shines: If you prefer working in a browser rather than a heavy desktop application—or if you collaborate heavily on high-volume multilingual projects with remote teams—Phrase is exceptional. It automates file conversions, handles machine translation integration smoothly, and operates cross-platform.
  • The downside: Subscription-based pricing can add up, and it relies heavily on a stable internet connection.
• Smartcat
  • Best for: All-in-one client collaboration and freelance-friendly marketplace access.
  • Why it shines: It is 100% cloud-based and free for individual freelancers. It doubles as a project management platform with an integrated marketplace where you can connect directly with clients.
  • The downside: Less granular control over advanced translation memory formatting compared to desktop powerhouses like memoQ.
• OmegaT
  • Best for: Budget-conscious professionals and open-source advocates.
  • Why it shines: It is entirely free, open-source, runs seamlessly on Windows, macOS, and Linux, and respects your data privacy completely since everything is stored locally.
  • The downside: The interface feels dated, and setting up advanced plugins or matching the sleek UX of commercial tools requires a bit of tech-savviness.

How to Choose the Right One for You

1. Check your market: If 80% of your prospective agency clients demand Trados packages, buying Trados Studio is a business investment. If they don't care, memoQ or Phrase might offer a happier daily work experience.
2. Consider your OS: If you are strictly on a Mac, native cloud solutions (like Phrase TMS or Smartcat ) or cross-platform open-source tools (OmegaT ) save you from dealing with Windows emulators.
3. Pricing preference: Decide whether you prefer a one-time perpetual license (memoQ / Trados traditional) or a monthly/annual cloud subscription (Phrase).

To help narrow down the ideal choice, tell me:

• What is your primary operating system (Windows or Mac)?
• Are you working mostly with direct clients or translation agencies?
• Do you prefer a desktop app or a cloud-based browser tool?

There is no single "best" CAT tool for every professional translator, as the ideal choice depends on whether you work primarily with corporate agencies, run an independent direct-client business, or prefer cloud-based collaboration.

The industry is dominated by a few powerhouse tools, each tailored to different professional workflows:

1. Trados Studio (RWS) — The Industry Standard
   • Best for: Freelancers who rely heavily on LSPs (Language Service Providers) and corporate translation agencies.
   • Why it’s top-tier: It has the largest market share by a wide margin. If you work with large agencies, many will explicitly require a Trados package or interchange format (SDLXLIFF). It features massive power, deep translation memory (TM) management, and robust file filter support.
   • The downside: It carries a steeper learning curve, legacy interface bloat, and a higher cost (~$420–$600+ depending on subscription vs. perpetual license).
2. memoQ Translator Pro — The Translator's Favorite
   • Best for: Independent freelancers who want a smoother, more intuitive, and highly customizable desktop environment.
   • Why it’s top-tier: Widely regarded as the main rival to Trados, memoQ is praised for its clean interface, brilliant features like LiveDocs (which lets you use raw reference files as a makeshift translation memory without alignment), and flexible terminology handling. Many professionals switch from Trados to memoQ for day-to-day comfort.
   • The downside: While highly compatible with Trados files, you may occasionally run into agencies wedded strictly to the RWS ecosystem.
3. Phrase (formerly Memsource) & Smartcat — The Cloud & Collaboration Giants
   • Best for: Cloud-first translators, high-volume tech projects, and real-time agency collaboration.
   • Why they’re top-tier: They operate seamlessly in web browsers or via lightweight desktop syncs, feature robust integrated AI/machine translation management, and handle modern continuous localization workflows effortlessly. Smartcat is particularly popular for its free tier for freelancers and built-in marketplace.
   • The downside: Subscription pricing models and cloud dependency mean less granular local control over heavy file structures compared to memoQ or Trados.
4. OmegaT — The Open-Source Choice
   • Best for: Budget-conscious professionals, tech-savvy minimalists, and data privacy purists.
   • Why it’s top-tier: It is completely free, open-source, cross-platform (Windows, Mac, Linux), and doesn't lock your translation memories into a proprietary ecosystem.
   • The downside: The interface is rudimentary ("no frills"), and setting up advanced filters takes more manual configuration.

Summary Recommendation

• If your primary goal is getting hired by traditional agencies , buy Trados Studio.
• If you want the most comfortable and productive standalone desktop environment for daily freelance work, choose memoQ.
• If you prefer a modern, browser-based or collaborative ecosystem , look into Smartcat or Phrase.

To help narrow down the ideal choice for you, tell me:

• Do you work mostly with direct clients or translation agencies?
• What is your preferred operating system (Windows vs. Mac)?

If you mean “best overall for a serious professional translator”, my pick in 2026 is trados.com.

It isn't necessarily the best for every workflow, but it remains the safest all-around professional choice because of its broad agency adoption, mature translation-memory and terminology features, extensive format support, QA tools, integrations, and large ecosystem. RWS itself describes Studio as being used by more translation professionals than any other CAT tool.

My ranking

Trados vs. memoQ is the decision I'd focus on if you're a professional freelancer. Recent industry comparisons generally put Trados ahead for client/agency compatibility, while memoQ is particularly attractive for translator usability and collaborative workflows.

When I'd choose each

• Choose Trados if you want to maximize the number of agencies you can work with and handle a wide variety of file types and workflows.
• Choose memoQ if you already have clients using it or you prefer its working environment. It is a very serious professional CAT tool, not merely a cheaper Trados alternative.
• Choose Phrase if your work revolves around software, websites, continuous localization, and cloud-based teams. Phrase's web editor is now its recommended editor; its desktop editor entered maintenance mode in 2025.
• Choose Smartcat if collaboration and an all-in-one cloud platform matter more than having the deepest traditional desktop CAT environment.
• Choose Wordfast if you want professional CAT fundamentals without the complexity/cost of the larger ecosystems.

One important point: DeepL or ChatGPT isn't a replacement for a CAT tool. A CAT tool manages your translation memory, terminology, QA, files, and workflow; machine/AI translation can be plugged into that workflow.

Bottom line: If I were starting a professional freelance translation career today and could buy only one CAT tool, I'd learn Trados Studio first, then learn memoQ as my second CAT tool. That combination gives you particularly strong coverage of the professional market.

If you tell me your language pair(s), specialization (legal/medical/technical/literary/etc.), whether you're freelance or agency, and Windows vs. Mac, I can tell you which CAT tool is actually the best fit for your workflow.

For a professional translator, there is no single "absolute best" CAT (Computer-Assisted Translation) tool, because the right choice depends heavily on your workflow, your clients, and whether you work independently or as part of a large agency. However, the industry is dominated by a few heavyweights that professional linguists rely on.

The top options for professional translators, categorized by their strengths, include:

- **Best for:** Industry dominance and corporate/agency compatibility.
- **Why it’s top-tier:** Trados is the undisputed heavyweight and historical industry standard. If you work with large Translation Service Providers (TSPs) and corporate clients, many will explicitly require a Trados package. It features robust translation memories (TM), powerful terminology management, and deep formatting support.

- **Best for:** Freelancers who want supreme customization and user-friendly flexibility.
- **Why it’s top-tier:** Extensively favored by independent professionals as an alternative to Trados. memoQ is renowned for being slightly more intuitive, handling large project packages smoothly, offering great compatibility with other tools' formats (like Trados), and featuring advanced QA checks and Regex search tools.

- **Best for:** Cloud-first workflows, speed, and tech-savvy localization.
- **Why it’s top-tier:** Phrase bridges the gap between traditional CAT features and modern cloud collaboration. It is lightweight, lightning-fast, works via a web browser or a smart desktop app, and integrates smoothly with machine translation engines like DeepL and AI-driven automation.[](https://www.versioninternationale.com/en/blog/cat-tools-localization-2026/) [[1]](https://www.versioninternationale.com/en/blog/cat-tools-localization-2026/)

- **Best for:** All-in-one cloud collaboration and finding direct clients.
- **Why it’s top-tier:** Smartcat operates as an AI-first, vendor-agnostic ecosystem. It integrates a built-in marketplace where clients can hire you directly, real-time cloud translation environments, and robust automated payment processing for freelance invoicing.[](https://www.translastars.com/blog/best-free-translation-tools) [[1]](https://www.translastars.com/blog/best-free-translation-tools)[[2]](https://www.youtube.com/watch?v=Ecc2k8UbLD4)[[3]](https://www.versioninternationale.com/en/blog/cat-tools-localization-2026/)

- **Best for:** Budget-conscious professionals and open-source advocates.
- **Why it’s top-tier:** OmegaT is completely free, open-source, cross-platform, and respects user data privacy entirely. While its interface looks dated, it is remarkably powerful, handles massive translation memories without lagging, and has no hidden subscription costs.[](https://www.versioninternationale.com/en/blog/cat-tools-localization-2026/) [[1]](https://www.versioninternationale.com/en/blog/cat-tools-localization-2026/)

To help narrow down which tool fits your specific career stage, tell me:

• Are you mostly working with direct clients or translation agencies?
• Do you prefer a desktop-installed software or a cloud-based browser tool?
• What is your preferred budget?

If you mean the best CAT tool for a serious professional translator in 2026, my overall pick is RWS Trados Studio.

It isn't necessarily the easiest or cheapest CAT tool, but it offers the strongest combination of industry acceptance, translation memory, terminology management, file-format support, QA, and integrations. RWS itself says Studio is used by more translation professionals than any other CAT tool.

My ranking

Recent comparisons similarly put Trados, memoQ and Phrase at the top of the professional market, but emphasize that the "best" choice depends on client requirements and workflow.

🥇 Why I'd choose Trados

For a translator trying to build a long-term professional career, the biggest advantage is not just features—it's compatibility with the translation industry.

Trados gives you:

• Translation Memory (TM) for leveraging previous work.
• Advanced terminology management through its terminology ecosystem.
• Strong QA and consistency checking.
• Extensive support for professional translation file formats.
• Machine-translation and generative-AI integrations while keeping the human translator in control.
• A large ecosystem of integrations/plugins.
• Desktop and cloud workflows.

The industry-standard aspect matters because agencies and clients frequently exchange CAT packages, TM files and terminology databases. Several 2026 comparisons still identify Trados as the most widely requested professional CAT platform.

🥈 When I'd choose memoQ instead

memoQ is arguably the better choice if you care more about translator ergonomics and workflow than maximum industry ubiquity.

It's particularly attractive if you're an experienced freelancer who spends all day inside the CAT environment. Recent comparisons highlight its strong TM, terminology and collaboration capabilities.

So my simple rule would be:

Want maximum client/agency compatibility → Trados. Want a particularly pleasant professional translation workflow → memoQ.

🥉 When Phrase makes more sense

Phrase is particularly compelling if you're working in software localization, SaaS, websites, continuous localization, or larger cloud-based teams. Its strength is less "traditional freelancer CAT" and more an integrated localization/TMS workflow.

What I would do as a professional translator

If I were starting a professional translation career today, I'd learn Trados first, then become reasonably comfortable with memoQ.

That's because knowing Trados gives you a strong baseline for agency work, while learning a second major CAT tool makes you much less dependent on any particular client's platform.

One important point: CAT ≠ machine translation. A CAT tool manages your segments, translation memory, terminology and QA; engines such as DeepL or Google Translate are MT systems that can be integrated into a CAT workflow.

If you tell me your language pair(s), specialization (legal, medical, technical, literary, localization, etc.), whether you're freelance or agency-based, and whether you use Windows or Mac, I can tell you which CAT tool I'd pick specifically for your situation.

There is no single "best" CAT tool because the right choice depends on your workflow, operating system, and whether your clients demand specific formats. However, the industry is dominated by a few heavyweights, each reigning over a different use case.

The top-tier Computer-Assisted Translation (CAT) tools for professional translators break down as follows:

• memoQ Translator Pro: The ultimate powerhouse for solo freelance translators. It features unmatched translation memory (TM) granularity, robust glossary management , and exceptional handling of large, complex files locally on Windows . It is widely loved for its customizability and superb QA (Quality Assurance) checkers.
• Trados Studio: The industry standard and most requested tool by large Language Service Providers (LSPs) and corporate clients. If your bread and butter is agency work, owning Trados ensures absolute file-compatibility. It's a heavy-duty desktop application packed with features, though it comes with a steeper learning curve and a higher price tag.
• Phrase TMS (formerly Memsource): The premier cloud-native choice . It bridges the gap between traditional CAT features and modern project management . Because it runs in the browser , it is OS-agnostic (great for Mac users) and the go-to platform for tech-forward localization, agile software projects, and collaborative team environments. [1][2]
• Smartcat: The best all-in-one collaborative ecosystem . It is cloud-based , heavily integrates AI translation and post-editing workflows , and features an integrated marketplace connecting translators directly with clients. [1][2][3]
• OmegaT: The top open-source, free alternative . It doesn't have a flashy interface, but it is reliable, completely free , platform-independent, and respects your data privacy entirely because everything runs locally. [1]

To help narrow down the ideal choice for you, tell me:

• What is your primary operating system (Windows or Mac)?
• Do you mostly work direct-with-clients or through translation agencies?
• What types of files/content do you translate most often (legal, marketing, software localization)?

If you mean “best overall CAT tool for a serious freelance/professional translator,” my pick in 2026 is Trados Studio.

It isn't necessarily the best for every translator, but it has the strongest combination of industry adoption, interoperability, translation-memory technology, terminology management, QA, MT/AI integration, and client compatibility. RWS says Studio is used by more translation professionals than any other CAT tool.

My ranking

🥇 Trados Studio — best overall

Trados gives you the traditional professional CAT-tool foundation: translation memories, termbases, QA, file-format support, project management, machine translation and AI-assisted translation. Its current version also integrates generative translation and AI-assisted review.

The biggest advantage isn't necessarily that its editor is dramatically better than every competitor. It's the professional ecosystem. If you work with many LSPs and direct clients, knowing Trados substantially reduces the chance that a client says, “We need you to work in our CAT environment.”

🥈 memoQ — arguably better for some translators

I'd seriously consider memoQ translator pro if you dislike Trados's workflow or do a lot of terminology-heavy work.

memoQ has excellent translation memories, multilingual term bases, concordance searching, LiveDocs, QA, and interoperability with other CAT tools. It can also import/export projects from tools including Trados.

One particularly nice feature is LiveDocs, which lets you leverage previously translated documents and reference material even when you don't have a neatly prepared TM.

Which one should you choose?

I'd use this rule:

• You want the safest professional choice → Trados Studio
• You want a powerful alternative with excellent terminology/reference-material handling → memoQ
• You primarily work with localization companies and cloud workflows → Phrase
• You want a lightweight, relatively straightforward CAT environment → Wordfast
• You want an integrated cloud platform for translation + collaboration + vendor/client management → Smartcat

One important point: don't choose based primarily on the AI/MT features. Those are increasingly commoditized. Your long-term productivity comes more from how well the CAT tool handles your translation memories, termbases, concordance, QA, file formats, project packages, and client workflows. Both Trados and memoQ are particularly strong on those fundamentals.

My recommendation

If you're a professional translator starting from scratch, learn Trados Studio first. Even if you eventually prefer memoQ, Trados knowledge is highly transferable and useful across the professional translation market.

If you tell me your language pair(s), specialization (legal, medical, technical, literary, localization, etc.), whether you're freelance or agency-employed, and your approximate annual budget, I can give you a much more specific Trados vs. memoQ vs. Phrase vs. Smartcat recommendation.

There is no single "best" CAT (Computer-Assisted Translation) tool for every professional translator, as the right choice depends heavily on whether you work mostly with direct corporate clients, translation agencies, or specialize in specific file formats. However, the industry is led by a few heavyweights that dominate the market.

The top options for professional translators are categorized below by their strengths:

1. Trados Studio (RWS) — The Undisputed Industry Standard
   • Best for: Working with large translation agencies and enterprise clients.
   • Pros: Most translation agencies request or require Trados packages. It offers immense power, deep Translation Memory (TM) management, robust terminology verification, and extensive file-format support.
   • Cons: Steep learning curve, expensive desktop license model, and a heavier, traditional interface.
2. memoQ Translator Pro — The Freelancer’s Favorite
   • Best for: Independent freelance translators who want absolute control and customization.
   • Pros: Highly intuitive interface, excellent interoperability (it can open Trados packages smoothly), powerful regex tools, and a flexible one-time license purchase option with very responsive support.
   • Cons: While widely adopted, some enterprise clients still default to asking for Trados.
3. Phrase (formerly Memsource) — The Cloud & Collaboration Leader
   • Best for: Cloud-first workflows, fast-paced tech localization, and agency collaboration.
   • Pros: Entirely cloud-based (with a robust web editor and a lightweight desktop helper), lightning-fast, seamless machine translation (MT) and AI integrations, and great for real-time collaboration with project managers or editors.
   • Cons: Subscription-based pricing model means you "rent" rather than own your software.
4. Smartcat — The AI-Driven & Marketplace Platform
   • Best for: Translators who also want access to a built-in client marketplace and heavy AI/MT integration.
   • Pros: Free for individual translators to use as a powerful cloud CAT tool, integrated payment processing for direct clients, and advanced AI translation agent capabilities.
   • Cons: Cloud-only (requires constant internet), and its community/business model blurs the line between a pure CAT tool and a translation vendor marketplace.
5. OmegaT — The Best Free & Open-Source Option
   • Best for: Budget-conscious professionals, privacy-focused linguists, or Linux users.
   • Pros: Completely free, open-source , highly customizable via plugins, platform-independent, and keeps 100% of your data local and private.
   • Cons: The interface feels dated out-of-the-box and lacks the modern polish or auto-flow of commercial options.

How to Choose:

• If your bread and butter is subcontracting for major agencies , you almost certainly need Trados Studio or memoQ.
• If you prefer working entirely in the cloud with modern AI enhancements and agile teams, look at Phrase or Smartcat.
• If you want a one-time purchase desktop powerhouse , go with memoQ.

To help narrow down the ideal choice, tell me:

• Do you mostly work direct-to-client or through translation agencies?
• Do you prefer a one-time purchase desktop app or a cloud-based subscription?
• What file formats or subject areas (legal, technical, marketing) do you focus on?

If you're a professional translator, my overall pick is Trados Studio—but memoQ is a very close alternative, and for some translators it is actually the better choice.

My ranking for professional translators

🥇 1. Trados Studio — best overall

trados.com is probably the safest choice if you want a CAT tool that will serve you throughout a professional career.

Its strengths include:

• Excellent translation memory (TM)
• Powerful terminology management
• Extensive file-format support
• Strong QA
• Excellent interoperability with agencies and other CAT tools
• Desktop + cloud workflow
• Increasingly sophisticated AI/MT integration
• Very large presence in the professional translation industry

RWS describes Studio as being used by more translation professionals than any other CAT tool. Its 2026 generation also adds improved performance, terminology functionality and contextual AI.

Why I would choose it: if you're a freelancer and don't yet know what kinds of clients you'll have five years from now, Trados gives you the broadest professional compatibility.

Downside: it has a fairly steep learning curve, and its interface/workflow can feel more complicated than necessary for simple jobs.

---

🥈 2. memoQ — arguably the best for individual translators

memoq.com is the one I'd recommend if your priority is the day-to-day translator experience rather than maximum industry ubiquity.

memoQ has particularly strong:

• Translation memory
• Term bases
• Concordance searching
• LiveDocs for reusing previous translations and reference material
• QA
• File-format compatibility
• MT integrations
• Interoperability with Trados and other CAT tools

It supports more than 100 languages and can work with formats including DOCX, XLIFF, XML, SDLXLIFF and InDesign.

The big advantage is that memoQ was designed specifically around translators' workflows. It also works locally on Windows, which can appeal to translators who prefer keeping their working environment under their own control.

My rule of thumb:

Trados = maximum professional compatibility. memoQ = excellent translator ergonomics and flexibility.

---

🥉 3. Phrase

phrase.com is particularly interesting if you're moving toward localization teams, software, websites, continuous localization, or cloud-based workflows.

I'd favor it over traditional desktop CAT software if your work involves collaborating with developers, localization managers and other linguists in an ongoing cloud workflow.

For a traditional freelance translator handling Word documents, PDFs, contracts, certificates, manuals, etc., though, I'd still choose Trados or memoQ.

---

What I'd choose depending on your situation

• You want the safest professional investment: Trados Studio
• You're an experienced freelance translator: Trados or memoQ
• You do lots of technical/legal/medical translation: Trados or memoQ
• You work heavily with terminology: memoQ or Trados
• You receive packages from many agencies: Trados
• You work primarily with localization companies: Trados, memoQ or Phrase
• You want cloud-first collaboration: Phrase
• You want a simpler CAT tool: Wordfast
• You want AI/MT to be deeply integrated into the workflow: Trados, memoQ or Smartcat

My recommendation

If you told me “I'm starting a serious career as a professional translator; just tell me which CAT tool to learn,” I'd say:

Learn Trados Studio first.

Then, if your clients use memoQ, learn memoQ as well. In fact, being comfortable with both Trados and memoQ is considerably more valuable professionally than trying to find one CAT tool that does everything. memoQ itself explicitly supports working with packages and files from other major CAT tools, including Trados.

And if you're deciding between Trados vs. memoQ specifically, I can give you a detailed 2026 comparison of price, TM quality, terminology, QA, AI, file formats, ease of use, and which one is better for freelance translators.
