Chrome extension · In development
Draw on web pages.
Explain with clarity.
WebMarkups is an upcoming Chrome extension for adding precise trendlines, levels, arrows, channels, and notes in a professional SVG layer above the webpage.
Free drawing stays on your device. Pro cloud storage will always be an explicit choice.
Release status
WebMarkups is being developed now.
The extension is in active development and testing. It is not currently available on the Chrome Web Store. The planned public release will be distributed through the official Chrome Web Store listing.
Development in progress
Chrome Web Store release planned. No public release date has been announced.
Built for clear feedback
The precision of a drawing tool.
The speed of a browser extension.
A separate drawing layer
Annotations render in a transparent SVG overlay. WebMarkups does not rewrite the webpage's own content or styles.
Designed for continuity
Drawings, settings, and launcher placement are designed to persist automatically for each page URL.
Low-friction controls
Choose tools, colors, undo, redo, delete, and close from a compact interface that stays near the launcher.
Guidance without clutter
Brief tooltips explain what each primary tool does and how to use it, while the first-release interface stays deliberately lean.
Place the pencil anywhere
Move the launcher to a comfortable edge. It stays inside the viewport and remembers its placement.
Common questions

Free annotation data stays in Chrome's local extension storage, organized by page URL. Pro cloud storage is being developed as an explicit per-page option.
What will Pro include?
Verified accounts, cloud sync, screenshots, and 5 GiB of private storage are planned at $1.99/month or $19.99/year (Save 16%). Pro is not currently available.
