Works with Claude, ChatGPT, and Gemini through open MCP
AI Pen Drive carries your context between AIs the way a pendrive carries files between computers. And unlike every other memory product, nothing is remembered without your yes.

retrieved 3 memories + 1 artifact from your pendrive
Picking up from yesterday: the color palette is final and the App Store description is drafted. Gemini stored the release flowchart. The open question was screenshots — here is a shot list that matches the palette…
Consent
Connected AIs can only propose memories. The Review Inbox is where you decide: approve, edit, or reject each one. Near-duplicates arrive grouped as a single decision, and keyboard triage clears a busy week in seconds.
Every candidate carries its origin: which AI, which conversation, which day, with a content hash you can verify later.


Receipts
Each time a connected AI reads from your vault, the Activity page records which client asked, what it asked for, and which memories it received. Consent granted from inside a chat is receipted the same way.
No other memory product shows you this. We think that should be embarrassing for them, not a feature for us.


Your vault
Every memory is plain text you can open, edit, re-scope, or restrict. Search is semantic, so “what did we decide about pricing” finds the decision, not the keyword.
Forget removes a memory everywhere, permanently. Export hands you the whole vault as JSON. Both are free on every plan, forever.


Cross-AI
The vault speaks MCP, the open protocol Claude, ChatGPT, and Gemini already understand. Add it once per AI and your context is simply there.
Your connector URL
https://ai-pen-drive-api.onrender.com/mcp
Connectors added on the web sync to the Claude and ChatGPT mobile apps on their own — your phone is covered the moment your desktop is.
Browser extension
Right-click any selection on ChatGPT, Claude, or Gemini and file it as a pending memory. A side-panel inbox lets you approve without leaving the page.
On your phone
Install the web app straight from the browser. Connectors you set up on the web follow into the Claude and ChatGPT mobile apps automatically, consent tools included.
ChatGPT import
Upload a ChatGPT data export and the pipeline extracts candidate memories, de-duplicates them, and queues every one for your review. Nothing lands active.
Security
Because it does. The full threat model is public — the short version:
OAuth 2.1 with PKCE
Every AI connects through the standard authorization flow and gets a token scoped to your vault alone. Revoke a connector and its refresh tokens die with it.
Encrypted at rest
Memory text is encrypted before it reaches the database. The threat model, including what we can and cannot see, is published on the Trust page.
Content-blind operations
Application logs never contain memory text. The operator console shows aggregates and metadata only, and every administrative action writes an audit record.
Real erasure
Deleting your account removes memories, artifacts, receipts, and events in one cascade. The forget button is a hard delete, not a soft hide.
