What we build
Coding agents can see images. Developers still spend half the bug report describing where something is. Casso is a menubar desktop app: draw numbered boxes, add short notes, capture locally, and paste a lean prompt into Claude Code, Codex, Cursor, Grok CLI, or anything that accepts images and paths.
We do not run a model on your screenshots. We do not upload them. The product is the gesture and the handoff.
Principles
- Agent-agnostic - no lock-in to a single CLI or IDE.
- Local by default - sessions live on your machine until you paste.
- Buy once - personal license, not another monthly tax on your toolchain.
- Desktop-native - any screen, not only a web preview you control.
