Build a clear report, compte rendu, or technical document from your evidence.
Start with Mistral. Finish with a report you trust.
NullDraft gives the project a structure before you start, so the screenshots and explanation are collected at the moment they are useful.
Turn the brief into a working plan.
Use the free Mistral API to break instructions into editable steps and see what proof each step needs.
Your plan stays tied to one project.

Collect evidence while you work.
Use the compact HUD to move through the plan, capture the screen, and keep the work moving without losing your place.
The review screen shows what is complete and what is missing.A HUD that stays out of the way.
The floating controls give you one job at a time: capture the evidence, move forward, and return to the work. No tab switching just to remember what comes next.

- Capture the whole screen or a chosen area
- Skip, revisit, or edit the plan when the work changes
