What is a memory vault for AI, and why should you own yours?
AI assistants each keep their own memory of you, locked inside their app. A memory vault is one portable store of your knowledge that any AI can use.

Quick answer
A memory vault is a single store of your personal knowledge (saved articles, notes, posts, documents) that you own and can take anywhere, instead of memory locked inside one AI app. MyMemory is a memory vault: you can export it at any time, and AI assistants can read it through an API or the Model Context Protocol.
Every AI assistant now "remembers" things about you. The catch is that each one remembers separately. What one assistant learned about your job, your projects or your preferences is locked inside that app. Switch tools and you start from zero.
Definition
A memory vault is a store of your personal knowledge that:
- you own, so you can export it and delete it,
- lives outside any single AI app, and
- any AI tool you choose can read, with your permission.
It is the difference between each assistant keeping private notes about you and you keeping one notebook that you hand to whichever assistant you're using.
What goes in it
Not just facts about you, but the things you've read and written:
- articles, threads and posts you saved,
- your notes and documents,
- transcripts of videos and podcasts you found useful.
That material is what makes an AI answer yours rather than generic.
Why owning it matters
- No lock-in. Your knowledge doesn't disappear if an app changes its pricing, its policies or shuts down, as Pocket did in 2025.
- One source of truth. Update it once and every tool sees the same thing.
- Control. You decide what is in it and who can read it.
How MyMemory works as a memory vault
- Collect: save from the web, the Chrome extension, and imports from X, Reddit, Instagram, YouTube, Notion and more.
- Use it yourself: search in plain English and ask AI questions about your saves.
- Hand it to your AI tools: developers can connect Claude Desktop, Claude Code and Cursor through the MyMemory MCP server, or any app through the REST API.
- Take it with you: export everything as JSON, CSV or Markdown at any time.
What it isn't
A memory vault isn't a replacement for your AI assistant, and it doesn't train a model on your data. It's the reference shelf your assistants read from when they need context.
