What does Web Highlights: PDF & Web Highlighter + Notes & Annotations do?
Web Highlights is a browser extension that lets you highlight text on any webpage or PDF. Available for Chrome, Edge, and Firefox, it works simply: select text, click the highlighter icon, and your highlight is saved — it stays even after you refresh the page. You can attach notes and color-coded tags to each highlight. The basic version works without an account and is completely free.
The extension also packs AI features. It uses Chrome's built-in AI to generate summaries of your highlights or entire pages, running offline with no data leaving your machine. You can also chat with a website, PDF, or YouTube video transcript — ask questions, get explanations, and explore content more deeply. Beyond AI, there's a reader mode for distraction-free reading, YouTube transcript highlighting, and a web clipper for bookmarks. All your data syncs across devices if you create an account (free or paid). Export to Notion, Obsidian, Markdown, PDF, or HTML.
This tool is a good fit for students working through research papers, professionals gathering information from multiple sources, or anyone who reads a lot online and wants to keep organized takeaways. The free tier covers the essentials; paid plans add syncing, reminders, and unlimited learning sessions. It's straightforward and reliable — no hype, just helpful.
