Draw, highlight, and point on any webpage. Built for teachers. Inkspot turns any webpage into a whiteboard. Click the toolbar icon and a clean, floating palette appears over the current page. Draw freehand, highlight, add shapes, drop text boxes, point with a laser, or use disappearing ink to guide attention without leaving a mark. When you're done, one click closes the overlay and the page is untouched. Built for teachers who present from the browser — Google Slides, Google Meet, YouTube explainers, shared PDFs — but useful for anyone who wants to mark up a screen during a meeting, review, or recording. ━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT'S INCLUDED ━━━━━━━━━━━━━━━━━━━━━━━━━ - Pen and highlighter with full color picker (hex, RGB, HSL) plus quick-access swatches - Rectangle, circle, line, and arrow shapes - Text boxes with adjustable font size and drag-to-position - Laser pointer — a red glow that follows your cursor, leaves no marks - Disappearing ink — strokes fade out after a moment, perfect for drawing attention without clutter - Eraser to remove individual strokes - Undo, redo, and clear-all - Adjustable stroke width - Cursor (pass-through) mode so you can still advance slides, scroll, and click underneath without closing the overlay - Works in fullscreen slideshow mode — follows you into presentation - Draggable toolbar — move it anywhere on screen ━━━━━━━━━━━━━━━━━━━━━━━━━ KEYBOARD SHORTCUTS ━━━━━━━━━━━━━━━━━━━━━━━━━ V — Cursor (click through to page) P — Pen H — Highlighter R — Rectangle C — Circle L — Line A — Arrow T — Text X — Laser pointer D — Disappearing ink E — Eraser Ctrl/Cmd + Z — Undo Ctrl/Cmd + Shift + Z — Redo Esc — Close overlay ━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━ Inkspot collects nothing. No accounts, no analytics, no telemetry, no network requests. Annotations live in your browser tab and disappear when you close the overlay. The extension has no backend — everything runs locally on your device. ━━━━━━━━━━━━━━━━━━━━━━━━━ LIMITATIONS ━━━━━━━━━━━━━━━━━━━━━━━━━ - Chrome and Edge on desktop only (no mobile browsers) - Does not work on chrome:// pages, the Chrome Web Store, or the built-in PDF viewer — browser restriction. For PDFs, use a web viewer like Google Drive. - Annotations do not persist between sessions by design ━━━━━━━━━━━━━━━━━━━━━━━━━ Feedback, bug reports, and feature requests welcome. What would help you teach better? Made with ♥ LOVE
