Transform how you research and read online. Web Highlighter is a powerful, privacy-first tool that lets you save the most important parts of any webpage, add your own thoughts, and generate instant AI summaries—all without your data ever leaving your computer. Best of all, Web Highlighter is completely free. Enjoy every feature without any hidden costs, subscriptions, or locked "pro" versions—ever. 🕵️ The Origin Story (A Note from the Developer) This extension started as a DIY project because I had 47 open tabs and the memory of a goldfish. I built it to solve my own disorganized research habits, but then I realized I wasn’t the only one drowning in unread articles. So, here it is—released into the wild for everyone to use. Since I built this for myself, you get the "Premium" experience by default. No subscriptions, no hidden "Pro" features, and no annoying pop-ups asking for your credit card. It’s 100% free because I like you (and because I think charging for highlights is just weird). ✨ Key Features Effortless Highlighting & Underlining: • Select any text to highlight or underline it instantly. • Use a sleek floating palette for one-click actions. • Choose from multiple colors to categorize your findings.
