PaintBox: every edit is a tool call.

The first fully agentic, Photoshop-class editor.

A mouse, a voice, a terminal and an agent all drive the same canvas through the same typed operations. Hand off at any step. Branch anything. Approve each change, or let it run.

Agentic by construction

One schema for every operation. Agents use exactly the tools you click.

Propose, then approve

Agents stage changes as proposals. Nothing lands until you say so. Or hand one a branch and let it run.

Local-first, WASM fast

A Rust engine compiled to WebAssembly. Your pixels stay in the browser until you publish.

Branch like code

Variants, checkpoints, compare. Retry cheaply on a throwaway branch.

Agents rebuilt software engineering. PaintBox is what happens when the same pattern reaches the rest of cognitive work. Images are the hardest case, so they come first.

Manual tools run locally on Rust and WebAssembly. AI needs Bike4Mind.

Are you an agent? You are welcome here too.
