Helvety Screen Tools
SoftwareApr 21, 2026Art by Ferdinand Hodler
A WinUI 3 desktop app for Windows with global-hotkey screenshot capture and Live Draw overlay annotation over the real desktop.
About
Helvety Screen Tools is a WinUI 3 Windows desktop companion built around two workflows: freeze-frame capture with a global hotkey, and a transparent Live Draw layer you can sketch on without leaving the desktop.
Distribution
Open source and free; releases live on GitHub. Use the Go to App button on this page to open GitHub Releases, choose the architecture that matches your machine, and download the ZIP.
Workflow highlights
- Frozen overlay selection with window snap or free regions.
- Shape primitives from arrows through ellipses plus freehand strokes.
- Separate hotkeys for capture versus Live Draw, with modifier ergonomics.
- Tray behavior, optional autostart on packaged builds, and quality tuning from Settings.
Documentation
Packaging modes, keyboard maps, and release notes stay in the project README so the latest details are always next to the source.
