Your memory,
on every AI.
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
Nothing is saved without your yes
Connected AIs propose memories, and every proposal waits as pending. You approve, edit or reject in the Review Inbox — or approve a single everyday memory by telling the AI in the conversation. Anything confidential, any batch, and anything that would replace an existing memory is confirmed by you inside AI Pen Drive. Near-duplicates arrive grouped as one 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
Every access, on the record
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
Readable, searchable, deletable
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 stops a memory being served to any AI the moment you click — every connector, instantly — with 30 days to change your mind in Trash before the encrypted residue is purged for good. What an AI already read and remembered on its own side is beyond any vault's reach, which is why "ask" and "blocked" memories are never sent at all. Export hands you the whole vault as JSON. Both are free on every plan, forever.
Cross-AI
One connector. Every AI in sync.
The vault speaks MCP, the open protocol Claude and ChatGPT already understand. Add it once per AI and your context is simply there — and the browser extension captures Gemini for review.
Your connector URL
https://ai-pen-drive-api.onrender.com/mcp
- 1In Claude: Settings → Connectors → Add custom connector, paste the URL.
- 2In ChatGPT (on plans that allow custom connectors): Settings → Connectors → Add, paste the same URL.
- 3Sign in once per AI. Each connection is scoped to your vault and shows up in your receipts by name.
Capture from wherever you think
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.
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
Built like it holds your memory
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
Account deletion erases memories, artifacts, receipts, and events in one cascade — after a 30-day grace window you can cancel. Forget removes a memory from retrieval instantly; the encrypted residue is purged for good 30 days later, restorable until then.
Others remember automatically. We ask first.

Their strength is automatic. Ours is accountable. As of September 2026, Claude's memory is on by default and adds topics as you chat (Anthropic, 25 August 2026).
Simple pricing. Trust is free forever.
