The four tools

Tools that run on your machine.

Butterfly Labs makes four small, serious tools: screen recording, dictation for India, an agentic coding CLI and a research workbench. Free. Most of it needs no account; Speak's free Cloud mode signs in with Google. Your keys and your files never leave your disk unless you say so.

One butterfly, four signatures.

Every tool carries the same mark. The lower-right wing is the only thing that changes: one colour and one small glyph, so you can tell them apart in a dock at a glance.

Butterfly Code

An agentic coding CLI built for accuracy on average models and a small token bill.

  • Nine tools, not thirty, because accuracy drops past ten
  • A ranked map of your repo on the first turn, about a thousand tokens
  • Autonomous loops that gate every task and commit on green
  • Any provider, including the ones running on your own hardware
