To get an AI assistant that both remembers your long-term preferences and operates directly through messaging apps , you have a few solid routes depending on whether you want an out-of-the-box solution or a custom setup.
Here are the best paths to use:
- ChatGPT (via official apps or custom integrations) : ChatGPT has the most mature persistent memory feature built-in, meaning it automatically recalls your preferences, background, and recurring instructions across chats. While OpenAI's official interface is its own app, you can link ChatGPT to messaging environments (like WhatsApp or Telegram) using automation tools or specialized API wrappers.
Meta AI / Muse : Meta has rolled out native personal AI agents designed to function right inside WhatsApp . It handles personal goals and communicates strictly like messaging another contact, making it a seamless choice if your primary messaging ecosystem is WhatsApp.
n8n or Custom Telegram Bots (DIY Route) : If you want absolute control over your data and memory, you can build a workflow using automation platforms like to connect a to an LLM API (like OpenAI or Anthropic) and back it with a permanent memory store (like a Google Doc or vector database). This lets the bot read your custom instruction/preference file before every single reply.
