02 — What does Sonn do?

Something cool, actually.

Sonn watches how you work, learns the decisions you make, and quietly teaches your agent to make them too — so every session starts smarter than the last.

You code
Claude works in your session
Sonn learns
spots the pattern, forms an opinion
Sonn steers
whispers the right move, before you ask
0
patterns learned
Every lap, it learns one more — the more you build, the smarter it gets. That's the loop no other memory tool runs.

04 — Questions

Good to know.

Only seats. Every capability — persistent memory, the Angel reasoning layer, whispers, unlimited projects, local-first privacy — is in both plans. Solo is one seat; Business is for teams that need more and want shared memory across them.
Full access to everything for 7 days — memory, reasoning, and whispers, no feature held back. You can cancel any time before it ends.
No. Sonn is local-first — your memory database lives on your machine and generation runs through your own model credentials. Your source never lands on a third-party server.
Sonn is built for Claude Code today, with more agents coming.
