A memory of its own for Claude on claude.ai
Counterparts gives Claude on claude.ai a memory of its own: who you are, what you’ve done together, what’s still open, carried from one chat to the next and written by Claude in its own words. It will connect to claude.ai, with nothing to install.
It’s coming soon, in beta. Sign up and we’ll email you when it opens.

How it will work
You connect it once. Counterparts is a custom connector: you add its address in claude.ai’s settings and paste a short block of instructions, and Claude can use it from then on. The Free plan allows one custom connector; on a Team or Enterprise plan, an owner adds it first.
Claude keeps the memory. At the start of each chat Claude wakes its memory, so it knows who you are and where you left off. As you talk, it saves what’s worth keeping without asking you first, and when you wrap up, it writes a short chapter of the conversation. You don’t have to tell it what to remember.
What matters stays. Memories fade unless they come up again, the way yours do. At the end of a chat you can say “dream”, and Claude goes over the day: it sorts what it kept, links it up, and lets the small stuff fade.
Beside Claude’s own memory. Claude’s built-in memory stays on; the two work side by side.
Yours to take or delete. Your account page will let you download your whole memory or delete it.
Who can read it
Your memory will be kept on a server we run, one store per person. It isn’t end-to-end encrypted, so we could technically read it: “we don’t read it” is our promise, not something the system enforces or records. What you say in claude.ai, and the memories Claude reads there, go to Anthropic. The privacy page says what’s stored and encrypted where.
Questions people ask
Does Claude on claude.ai remember me between chats?
Partly. A new chat doesn’t load your earlier conversations. It starts with your memory topics, which Claude picks as you chat, your instructions and, in a project, the project’s files. On a paid plan Claude can search old chats when you ask. Counterparts adds a memory Claude keeps itself: notes in its own words about you and your work, which come back when the next chat wakes the memory. Why Claude forgets between chats has the details.
When will Counterparts for claude.ai be available?
It’s coming soon, in beta. There’s no date yet. Sign up on this page and we’ll email you when it opens.
Do I need to install anything?
No. It will connect to claude.ai as a custom connector: you add an address in claude.ai’s settings, and Claude can use it from then on. On a Team or Enterprise plan, an owner adds it first.
Will it work in the Claude phone apps and Claude Desktop?
It should. Anthropic runs custom connectors from its own cloud for every Claude client, so a connector added on the web follows your account to the apps; we’ll say which ones we’ve tried when it opens. On a Mac, Claude Desktop can also use the local install today.
How is it different from Claude’s built-in memory?
Claude’s memory saves topics about you. Counterparts keeps a memory the way a person does: Claude writes down what it learned in its own words, and memories fade unless they come up again, so what matters stays. The two work side by side; you don’t turn Claude’s own memory off.
Who can read my memory?
It will be kept on a server we run, one store per person, and it isn’t end-to-end encrypted, so we could technically read it. “We don’t read it” is our promise, not something the system enforces or records. What you say in claude.ai, and the memories Claude reads there, go to Anthropic. The privacy page says what’s stored and encrypted where.
Can I use Counterparts today?
Yes, with Claude Code on a Mac or Linux, or Claude Desktop on a Mac, as a free, open-source local install that keeps the memory on your computer. Counterparts for Claude Code has the Claude Code steps, and the Quickstart has Desktop’s.
