Web Highlighter Chrome extension

Core highlighting, notes, and tags are free to use. AI features like summaries and semantic search may have usage limits or paid tiers for heavier use.

It needs to read and overlay content on pages you highlight, and content sent for AI summaries is processed by a cloud service. Avoid highlighting sensitive text if that concerns you.

Select text on a page, choose a color to highlight it, and optionally add a note or tag before saving it for later.

Yes, it supports highlighting and annotating moments in YouTube videos in addition to standard webpage text.

Yes, it can produce AI-generated summaries of the passages you've highlighted.

Yes, it supports semantic search across your saved highlights and summaries, not just exact keyword matches.

Liner, Glasp, and Weava are common alternatives for highlighting, tagging, and organizing web content.

Yes, you can attach custom tags to individual highlights to organize them for later retrieval.

Some sites reload or rebuild their content dynamically, which can prevent highlight overlays from reattaching; try re-highlighting after the page fully loads.

Export options depend on the extension's current settings menu; check within the extension for available export or sync features.
