IS THERE AN APP THAT REMEMBERS EVERYTHING ABOUT ME?
Yes. A small category of products now does versions of this: a memory of you that outlives any single chat and follows you between AI assistants. As of August 2026 the main options are Mem0's OpenMemory, Pieces, Limitless and AI Passport. They differ in what they remember, how assistants connect, and who controls what gets shared.
WHAT EACH ONE REMEMBERS
Mem0 / OpenMemory
A browser extension and API that extracts preferences and facts from your AI conversations and injects them into ChatGPT, Claude, Gemini, Perplexity and Grok. Built by a developer tools company, and the memory flows through the extension. The lightest way to make chat preferences follow you.
Pieces
A local-first timeline of your computer life: research, chats, notes, meetings. Assistants reach it over MCP. Strong if you want a second brain of everything you did on your machine. Broad capture of your screen activity is also the privacy trade to weigh.
Limitless
A wearable pendant and app that records and transcribes your conversations, with an API and an MCP connection into assistants. Strongest for remembering your spoken life rather than your working context.
AI Passport
A passport of you: memories, preferences and context from the accounts you connect, stored in one place you own. Any AI you allow can ask for it. Each app gets a scoped pass you approve, and every access leaves a receipt you can read.
THE DIFFERENCES THAT MATTER
| OpenMemory | Pieces | Limitless | AI Passport |
|---|
| What it remembers | Facts extracted from AI chats | Your on-screen activity | Recorded conversations | Memories, preferences and connected accounts you choose |
|---|
| How assistants connect | Browser extension, MCP | MCP | API, MCP | ChatGPT connector, Claude connector, MCP, server API |
|---|
| Who approves sharing | Install once, injection is automatic | Local permissions | API keys | You approve each app per category, sensitive items ask again |
|---|
| What you can audit | Stored memories | Local timeline | Lifelogs | A receipt for every access |
|---|
HOW TO CHOOSE
If you mainly want chat preferences to follow you between assistants, OpenMemory is the lightest start. If you want a private index of everything you do on your computer, Pieces is the most ambitious. If you want your spoken conversations remembered, Limitless is the one wearing a microphone. If you want one governed memory of you, fed by the accounts you actually use and shared with any AI only on your terms, that is the job AI Passport was built for.
WHERE AI PASSPORT FITS
AI Passport is a permission-based context and identity layer for AI. You connect the assistants and apps you already use, review what they propose to remember, and control which apps can read which categories. Your memory is not trapped in one vendor: you can export it at any time, and deletion actually propagates.
It works with ChatGPT and Claude today through published connectors, and with anything that speaks MCP. It is free for life for individuals.
FAIR QUESTIONS
Does it work with ChatGPT and Claude?
Yes. AI Passport has a published ChatGPT connector and Claude connector, and anything that supports MCP can connect too. You approve each app once, per category of memory.
Who answers questions about my data?
An AI we run ourselves, on machines we control. Apps receive the answers you approved, not your raw archive.
What does it cost?
Free for life for individuals. Companies building on it pay a flat platform fee, described on the startup page.
Can I get my data out?
Yes. You can export your data at any time, and you can delete memories one by one or entirely.
ONE MEMORY, EVERY AI YOU ALLOW
Claim your passport and stop re-introducing yourself to every assistant.
