Page Anchor - Web Annotation & Drawing

Freehand drawing, shapes, and text annotations directly on web pages with persistent storage and customizable shortcuts.

**Draw on any web page and keep your notes there.** Page Anchor adds a small, draggable toolbar to the pages you choose. Pick a tool, draw, and your work is saved to that exact URL, ready when you come back. No screenshots, no exporting, no switching apps. **Tools** - Pen and highlighter with adjustable colour and width - Rectangle, circle, line, arrow and double-arrow shapes - Text notes you can type, move and edit - Eraser, undo and redo - Select and move anything you draw **Made to stay out of the way** - The toolbar can be dragged anywhere and remembers its position. - The interface lives in a Shadow DOM, so it never changes how a page looks, and a page can never change the interface. - Single-key shortcuts only work while drawing mode is on, so normal typing and website shortcuts keep working. - Every shortcut can be rebound, with warnings for keys the browser has reserved. **Your work stays yours** - Annotations are stored only in your browser, per URL, and restored automatically. - Annotations are anchored to page elements, so they follow content when a layout shifts. - Export all annotations to a JSON backup and restore them whenever you want. - No accounts and no uploads. **Fast on low-end hardware** A fixed-viewport dual-canvas engine, viewport culling and pointer coalescing keep drawing smooth on budget laptops and Chromebooks. Optional stroke simplification shrinks saved data without a visible difference. Page Anchor is free and open source (MIT).
