ChatFolders is a browser extension that brings organization to AI chat interfaces. Instead of scrolling through a flat list of conversations, you can drag and drop chats into color-coded folders across ChatGPT, Claude, Gemini, and Grok — all managed from a single extension. You can also bookmark, tag, and search conversations, and set up auto-rules that sort new chats into the right folder automatically. Everything is stored locally in your browser: no account required, no cloud sync by default, no tracking. The free tier supports up to 5 folders. A paid upgrade unlocks unlimited folders, sub-folders, cross-device sync, and additional features. A practical tool for anyone who runs dozens of AI conversations and needs a way to keep them findable.
