Your team’s context lives in six people’s heads. Not anymore.
CyberFox Brain is a shared, versioned knowledge base that every teammate’s AI reads and writes directly — so context survives the end of a session instead of dying with it.

Your AI is smart. It just doesn’t remember anything.
Context dies at the end of a session
Every new chat starts from zero. Decisions, conventions, and the reasoning behind them have to be re-explained, or they're gone.
Each teammate's AI knows a different version of the truth
One person's assistant learned the auth flow last week; another's is still working off a stale mental model. Nobody notices until something breaks.
Hand-written notes go stale
Wikis and docs rot because nobody is paid to maintain them. A knowledge base only stays current if updating it is somebody's job — or something's job.
How it works
One connector. Every session. One shared brain.

Your AI reads and writes the brain
Every session opens by calling start_here:
> start_here("eversmile")
conventions: "## Session ritual — search before
you write, append_note for logs…"
recent_activity:
- Maya: wrote decisions.md (2h ago)
- Priya's session: appended tasks.md (40m ago)
open_tasks: 3 unchecked in tasks.mdEveryone sees the same brain
Every teammate’s session reads and writes the same notes, with a role that controls what they can change.
What you get
Built for a knowledge base that AI agents actually write to
Full version history
Every note keeps every past revision. Restore any of them with one call — nothing an AI writes is ever a one-way door.
Per-user attribution
An append-only activity log records who made every write — a teammate or their AI session — so you always know where a note came from.
Conflict warnings, not silent overwrites
Optimistic locking flags it when two sessions edit the same note at once, instead of letting one quietly clobber the other.
Soft delete & undelete
Deleted notes aren't gone — they're recoverable, so an over-eager cleanup pass never costs you real work.
Owner / editor / viewer roles
Set exactly who can read and who can write, per brain, without building your own permissions system.
Self-serve brains & invites
Spin up a new brain and add teammates in seconds — no admin ticket, no waiting on IT.
