Open Draw by ThousandMilesAI

Open Draw turns any web page into a whiteboard. Click the toolbar button and annotate the page right where it is, with no screenshots or switching apps.
Made for teaching and presenting
• Pen and highlighter for freehand marks
• Arrows and shapes (rectangle, ellipse and more), with a square or circle when you hold Shift
• Text notes anywhere on the page
• Laser pointer that fades by itself, and a spotlight that dims everything except where you point
• Eraser, undo, redo and clear

Stays out of the way
• One compact toolbar you can dock to any edge of the screen
• Keyboard shortcuts for every tool (P, H, A, R, T, E, L, S)
• Press Esc to go back to the page, and click Resume to keep drawing
• The page stays scrollable while you draw

Your notes are kept
• Annotations are saved in your browser, per page, and come back when you return
• Export the visible page and your annotations as a PNG
• Download your annotations as a file and import them again later

Private by design
Open Draw runs only on the tab where you click it. It collects no data, sends nothing anywhere, and makes no network requests. Everything stays on your device.
