Tell AI once.
It remembers, everywhere.
Portamem gives every person and every agent one private memory, built for Claude, ChatGPT and Gemini. Say how you work once, and stop repeating yourself.

Questions
The short answers. Ask us anything else.
-
Claude, ChatGPT and Gemini to start.
-
No. Islands never connect. An agent that works for you gets read-only permission to chosen parts of your island, which you can take back. Nothing is copied and no link is made.
-
Passwords and secrets, raw logs, one-off outputs, and knowledge that already lives in your files. For those it keeps a pointer.
-
There's no waitlist and no pricing yet. Tell us who you are and what you'd use Portamem for, and we grant access one request at a time. A good reason helps.
-
Yes. Your island exports as a single file, and deleting it removes that file.
-
Built-in memory usually stays inside one app. Portamem is one memory built for all of them, and it belongs to you.
The problem
What we're solving
Nine ways AI memory lets people and agents down today.
You explain your role, your stack and how you like answers, again, in every new chat.
You fix the same mistake today that you already fixed last week.
Move from ChatGPT to Claude or Gemini, and everything it knew about you stays behind.
Every run rediscovers the deploy step or the error it already solved yesterday.
When work passes from one agent to another, or to a person, what was learned doesn't go with it.
An agent working for you doesn't know your always and nevers, so it can't respect them.
Memory that copies your docs keeps a second version that quietly drifts from the real one.
Once the context window fills up, the decisions you made at the start fall out of it.
It usually sits inside someone else's product, hard to take with you or to delete for good.
Benchmark
Benchmarking Portamem
How often an AI answers correctly when it relies on its memory.
Sample data · not real results
Long conversations over many sessions: can the AI still recall what was said weeks ago?
Accuracy (higher is better). Sample numbers for layout only; real results will be published with their method.
