The app
An AI partner that lives
on your Mac and knows you.
It remembers you across every model and runs on your own machine. It also acts for you, driving a real browser with your logins, running your tools, and using your keys without ever seeing them.
Requires macOS. Core is AGPL open source, free forever.
What makes it a partner
Memory that is actually yours
Feed it a paper, a repo, or a whole manual, or just work with it day to day. It learns once, keeps what it learned in a substrate on your machine, and still knows it after restarts, model swaps, and updates.
Any AI, three ways
Use a subscription you already pay for (Claude, ChatGPT, or Kimi), your own API keys, or a model running fully on your Mac. Swap the engine whenever you like. The mind that knows you does not change with it.
Yours, and private
Run a local model and nothing ever leaves your Mac. No account to sign into, no cloud to trust, nothing phoning home. It is your AI, on your hardware.
It does real work, safely
Ask it to and it drives a real browser with your own logins, runs your tools, and calls your APIs through a vault that hands it the result and never the key. A prompt that tries to steal your secrets gets nothing.
Works with any AI.
Switch per pane with /model. Your choice sticks.
And the everyday things, done well.
Global dictation
Your voice becomes text in any app, wherever the cursor is.
Meetings, captured
It listens with you and you leave with the notes written.
Live voice
Talk to it out loud. It answers back in real time.
Advanced cockpit
Several threads side by side, each with its own engine.
Image generation
Make images through your own Gemini or ChatGPT plan, right in the conversation.
AirDrop between Macs
Move it to another Mac. It arrives knowing everything.
Autonomous mode: opt-in, budget-capped.
