In the age of AI, we don't suffer from a lack of information—we suffer from a lack of structure.
We realized that while we were having breakthrough conversations with AI models and reading profound content on the web, most of it was slipping through our fingers. Copy-pasting was tedious. Bookmarks were forgotten. The knowledge was lost.
Chat Highlight wasn't built to be another social network. It was built as a productivity tool for serious learners.
We asked ourselves: What if a highlighter could understand context? What if it knew the difference between a user's prompt and an AI's answer? What if your browser extension acted as a "primary filter" for your second brain?
This is our signature feature. Unlike traditional highlighters, Chat Highlight features a specialized Chat Note Mode. It recognizes supported AI chat page structure across ChatGPT, Claude, and Gemini — automatically. It categorizes content into "Prompts" and "Answers", turning a messy chat log into a clean, reviewable study note.
We respect your data sovereignty. Chat Highlight operates primarily on your device using local storage for instant, zero-latency interaction. We've unified our authentication to a single, secure cloud login — no more separate local accounts. Yet all core capture still happens locally for zero-latency privacy. We do NOT use your data to train AI models.
The browser extension is for capturing; the Cloud Dashboard is for connecting. We treat your highlights not as temporary scribbles, but as long-term assets. With global search, tagging, and folder management, we help you build a library that grows in value over time. Export directly to Notion, Markdown, or HTML to integrate your highlights into your existing workflow.
A secure cloud login connects all your devices. Enjoy full bilingual support in English and Chinese, tailored to your native reading experience.
As an independent developer and researcher, I believe that the future belongs to those who can curate their own knowledge. I am building Chat Highlight to be the ultimate bridge between the web, your AI tools, and your mind.
Stop losing your best thoughts. Start highlighting with purpose.
