2Everything opens in placeNo jump to a sub-page (Composio exiles you to one per toolkit): the panel expands inside the grid, right under the tile you clicked — see-it-work on the right, tools & triggers tabs on the left, close and keep browsing.
3The shrinking askOne story, no terminal soup: the three highlighted details physically fly out of the first ask into the memory panel. The short ask then runs with the panel flashing RECALLED. −74% is computed from the real strings (100 → 26 chars). The board below answers "what else does it remember" — grouped by how it helps, not by app.
Tools that remember

Say it once. It's remembered.

Your users explain themselves once. The details become memory — recalled on every ask after, for that user only.

4The board is aliveA recall sweep runs left to right: every three seconds one fact lights up with its RECALLED chip, and the log line below narrates the actual run that used it — which client, which tool, and the ms it took. Numbers are one illustrative user's first month.
A month in

Your agent just knows.

Eight of the twenty-three facts one user's agent picked up in its first month — being recalled live, mid-run, private to that user.

OAuth, handled

Your users sign in.
You write none of it.

Every toolkit ships with its auth flow already built. The page on the right is the real one — wearing your logo, at your domain. You send a link; we handle consent, tokens, refresh and revocation.

01
You create a connect linkOne API call, or a click in the dashboard. No OAuth app to register, no redirect URIs to babysit, no provider quirks to read up on.
02
Your user approves — on this pageReal OAuth with the provider. They see exactly what's requested; the provider's own consent screen is final.
03
Your agent gets scoped toolsOnly that user's grant, only the tools you allow. Tokens stay server-side — your code never touches a credential.
✓Refresh, expiry and re-consent handled for you.
✓Revoke one user, one app, one click.
✓MCP OAuth too — including dynamic client registration.
