What it does
while you work.
Memory
Written to disk
Plain text you can open, edit and delete. A file, not a black box.
Local
Your machine only
Real files, real commands. Nothing leaves unless you send it.
Schedule
Runs unattended
Briefings and backups on a cadence you describe in a sentence.
Delegate
Splits the work
Subagents with their own terminals, reporting into one thread.
Extend
Speaks your stack
MCP servers, shell tools and HTTP endpoints, wired in directly.
Platforms
One build
per desk.
