Bullet-point text summarization

You need a bullet-point summarizer that preserves 100% of the numerical data—not just the main ideas, but also every figure, percentage, date, statistic, measurement, range, and quantity in the original text.

The best approach is to use a summarizer with explicit instructions to preserve numbers and verify them against the source.

Recommended summarizer prompt

You can use this prompt with ChatGPT or another AI summarization tool:

:::writing{variant="document" id="58314"} Summarize the provided text using clear, concise bullet points.

Critical requirements:

• Preserve every numerical value from the original text. Do not omit, round, estimate, or alter any number.
• Include all dates, years, percentages, statistics, monetary amounts, measurements, quantities, ranges, ratios, formulas, sample sizes, and numerical comparisons.
• Keep each number attached to its correct label, unit, context, and meaning.
• Preserve negative values, decimal places, signs, units, and ranges exactly as written.
• Include numerical data found in tables, footnotes, captions, examples, and parenthetical statements.
• Organize related facts under descriptive headings and use nested bullets where helpful.
• Remove repetition and unnecessary wording, but never remove unique factual or numerical information.
• Do not introduce numbers or facts that are absent from the source.
• If a number is ambiguous, inconsistent, or illegible, flag it rather than guessing.
• If the source is too long to summarize completely, state that explicitly instead of silently omitting information.

Final verification: Before submitting the summary, compare it with the source and check that every numerical value is accounted for. Include a final section titled "Numerical Data Check" listing any numbers that could not be verified or confirming that all numerical data has been retained.

Output format: Bullet points, grouped by topic, with concise wording and complete numerical fidelity. :::

My recommendation

Start with Humanit for straightforward summaries or Musely if numerical statistics are especially important. No AI summarizer can guarantee that every number will be retained, so use the numerical verification prompt above for critical documents.

One question so I can recommend the best fit: What do you mainly want to summarize?

1. What type of material?

PDFs and research papers

Web articles and reports

Books and textbooks

YouTube videos and lectures

Excel files, tables, and financial reports

---

2. How strict is the numerical requirement?

Every number, without exception

All important statistics and figures

---

3. Budget

Free

Paid is fine if more reliable

[Find my best summarizer]

For your specific need, I’d recommend a summarizer that has an explicit preserve all numbers and statistics instruction, rather than one that simply creates a short overview. No AI tool can guarantee perfect numerical retention, so look for one that lets you verify the figures against the original article.

Here are my top picks based on their advertised features.

How to ensure the figures survive summarization

Whichever tool you choose, use this instruction:

Copy-and-paste prompt

Summarize this article into concise, well-organized bullet points.

CRITICAL REQUIREMENTS: - Preserve every statistic, percentage, monetary value, date, year, sample size, measurement, and numerical comparison exactly as stated. - Do not round, recalculate, combine, or omit any figures. - Keep each number attached to its original context and units. - Preserve relevant caveats, time periods, and source attributions. - Do not introduce facts that are absent from the article. - If the summary would be too short to retain all numerical details, prioritize completeness over brevity. - Finish with a separate "All Figures and Statistics" checklist for verification against the original article.

[Copy prompt]

My recommendation: Start with SmartSummarize if you want a simple, free workflow. If retaining every figure is essential for financial, scientific, or professional work, compare its output against the original and use the separate statistics checklist to catch omissions. Even tools explicitly designed to preserve numbers can make mistakes.
