Chalk
A lightweight Windows overlay for drawing on your screen. Point things out with arrows, boxes, freehand ink and text during tutorials, screen shares and presentations.
It sits in your system tray until you need it. Hit a hotkey and a transparent draw layer appears over whatever you’re doing; mark it up, then toggle back, without juggling windows or alt-tabbing mid-recording.
Built with AI agents - idea to public release in 6 days, about 3 hours of my hands-on time. The same method I teach.
Ships as an installer or a single portable .exe, needs no admin rights or .NET install, and it’s free under the MIT licence.
- Freehand, arrow, rectangle, circle and text tools.
- Colour palette plus thin, medium or thick strokes.
- Hotkey-driven from any app - summon and dismiss the draw layer with Ctrl + Alt + D.
- Draws over anything, DPI-correct on whichever monitor your cursor is on.
- Runs from the system tray, with an optional launch-on-startup so it's ready when you record.
