Page Annotation

You audit a site across fourteen tabs. You spot issues on page three, seven, and twelve. By the time you open a doc to log them, you’ve lost which tab had the broken heading.

Page Annotation puts highlights, sticky notes, and numbered stamps directly on the page. Close the browser. Come back tomorrow. Still there.

Double-click for a note. Select text to highlight. Press 1 to stamp. Everything persists.

Read-Only by Default

Browsers were never built for writing on webpages.

You can bookmark a page. You can screenshot it. You can copy text into a separate document. But you can’t put a sticky note on a paragraph.

So auditors screenshot and paste into Google Docs. Designers mark up PDFs of their own live site. Developers keep a notepad open beside the browser and hope they remember which tab had the issue.

The workaround is always the same: leave the browser, lose the context.

Page Annotation stays in the browser. Annotations live on the page itself — anchored to the URL, stored locally, loaded automatically on every revisit.

Five Tools in
One Toolbar

Activate once. Every annotation type available immediately.

Highlight → Select any text. Five preset colours on keyboard shortcuts: Q (red), W (green), E (orange), R (yellow), T (blue). Custom colours via picker — your three most recent are saved.

Sticky Notes → Double-click anywhere. A coloured pin appears. Click to expand into a text editor. Type your note. Click away to collapse. Drag to reposition. Auto-numbered.

Stamps → Press 1 through 5 to place numbered markers. Click anywhere to stamp. Icon stamps too — checkmark, cross, warning, alarm, info — for pass/fail annotations.

Draw → Press A for arrow, L for line, B for box. Click and drag. Use + and − to adjust stroke width from 1px to 100px. Every drawing uses the selected colour.

Context Menu → Right-click any annotation to edit, recolour, or delete. No hunting through menus.

Close the Browser.
Come Back Tomorrow.

No account. No cloud sync. No expiration.

Page Annotation stores everything locally in your browser. Keyed per URL — hostname plus pathname. Each page holds its own highlights, notes, stamps, and drawings independently.

Close the tab. Close the browser entirely. Reopen the URL next week. Activate Page Annotation. Everything reappears exactly where it was.

Modern web apps don’t trigger full page reloads when you navigate. Page Annotation listens for popstate and hashchange events. When the URL changes within a single-page app, it saves annotations for the old URL and loads annotations for the new one automatically.

A small pulsing cyan dot appears in the corner of any page with saved annotations — a silent reminder that this page has your notes on it.

The 14-Tab Audit

Annotations aren’t a report about the site. They’re on the site.

You’re reviewing a client site. Thirty-seven issues across fourteen pages.

Without Page Annotation: screenshots, a shared doc, “see screenshot 14.png for reference.” The doc hits 4,000 words. Nobody reads it.

With Page Annotation: stamp each issue with a number. Add a sticky note explaining what’s wrong. Highlight the broken text. Share your screen — walk through each page with the annotations visible, in context, on the actual website.

The client sees exactly what you see, exactly where the problem is.

Open Quick Launch Toolbar (Ctrl+Shift+Space). Type “pa”. A list of every page you’ve annotated appears — sorted by domain, each entry showing how many highlights, notes, stamps, and drawings. Your annotation history becomes a browsable index.
