Sticky Highlights

About

Highlight anything, anywhere — and never lose it again.

Most highlighting extensions break the moment a page reloads or updates its content. Sticky Highlights is built specifically to survive that: it actively watches the page and restores your highlights even on sites that constantly re-render their content, like NotebookLM, AI chat apps, and other dynamic web tools.

WHY STICKY HIGHLIGHTS

• Built to last — highlights are restored automatically, even after the page changes, reloads, or the content is re-rendered by the site itself
• Works exactly where you choose — nothing happens on any site until you enable it, so there's no clutter and no accidental highlighting
• Organize as you go — colors, notes, and tags on every highlight, searchable instantly from the side panel
• Export your way — download your highlights as Markdown, JSON, or CSV, with a fully customizable template so the output matches exactly how you take notes (Obsidian-style nested bullets, blockquotes, your call)
• Totally private — everything stays on your device. No account, no server, no tracking.

HOW IT WORKS

1. Select any text on a page you've enabled
2. Pick a color from the popup — done
3. Find every highlight later in the side panel: search by keyword, tag, color, domain, or date

PERFECT FOR

Researching inside NotebookLM, reading long articles, studying from online textbooks, or collecting quotes across dozens of tabs — anywhere you need your highlights to actually still be there next time you open the page.

YOUR DATA STAYS YOURS

Sticky Highlights stores everything locally in your browser. Nothing is sent to a server, no analytics, no ads, no tracking. You can export or delete your data at any time.
