From loading a photo to exporting a fully annotated, scaled image — the whole workflow in a few minutes.
The problem
Marking up a photo shouldn't take an hour.
- ✕Photoshop is overkill
You need a few arrows and measurements, not a poster.
- ✕Screenshot tools are too basic
No real measurements, no project files, no professional output.
- ✕Web tools need internet
On a job site or in a client meeting they fail exactly when you need them.
One job, done properly.
A focused desktop tool for people who annotate photos for a living — fast, precise and offline.
- Opens in seconds, works immediately
- Fully offline
