Hi HN,

I built a browser extension that auto-saves your AI conversations locally.

Problem: I kept losing important ChatGPT/Claude conversations. No proper export, chats disappear, browser crashes.

Solution: ChatCapture Pro monitors chat pages and saves messages to IndexedDB. Export as HTML, JSON, or plain text. 100% local, no cloud.

Tech: Manifest V3, MutationObserver for real-time detection, IndexedDB for storage.

Free: 5 chats, JSON export Pro: €4.99 one-time (unlimited)

Built with for privacy-conscious AI users.
