ChatGPT History Deep Searcher

Search ChatGPT history, scan selected conversations, cache snapshots, and navigate keyword hits with a minimap.

Overview Search ChatGPT history, scan current or selected conversations, cache local snapshots, and navigate keyword hits with a minimap. **ChatGPT History Deep Searcher** is a free Chrome extension for searching and navigating your ChatGPT conversation history. It helps you find past prompts, answers, code snippets, troubleshooting notes, research discussions, and long conversation fragments without manually scrolling through ChatGPT history. The extension can work in two main ways: 1. Search across ChatGPT history Use ChatGPT's official history search to find matching conversations, choose the conversations you want, and scan them locally. 2. Search the current conversation Open a ChatGPT conversation tab, click the extension, and scan the current conversation. This is useful when you are actively chatting and want to quickly locate earlier context in the same thread. **Key features** - Search across your ChatGPT history - Scan the current ChatGPT conversation tab - Select and scan multiple matching conversations - Highlight keyword matches inside scanned conversations - Open a floating Conversation Navigator window - Search again inside a scanned conversation snapshot without calling ChatGPT search again - Navigate results with a minimap and hit list - Cache scanned conversation snapshots locally in your browser - Reuse local cache and append newly scanned content when possible - Protect useful cached snapshots from ChatGPT history loading gaps - One-time rescan option for rebuilding selected conversation caches - Warning prompts before risky cache replacement - Works only on ChatGPT pages to avoid accidental scans from unrelated tabs - Completely free to use - No account registration required - No database setup required - Does not connect to any third-party server **Conversation Navigator** After a scan, the extension opens a floating Conversation Navigator on top of the ChatGPT page. The navigator displays a static snapshot of the conversation, keeps the original ChatGPT page usable behind it, and lets you: - Search for a new keyword inside the same snapshot - Jump between keyword hits - Use the minimap to locate matches visually - Keep chatting in ChatGPT after closing the navigator This makes the extension useful not only for searching old history, but also for working inside an active long conversation. **Local cache** Scanned snapshots are cached locally in your browser. Later scans can reuse cached snapshots and append newly scanned content when possible. This is important because very long ChatGPT conversations may sometimes load incompletely. A previously saved local snapshot can help preserve content that may not load correctly later. Please use one-time rescan carefully. If ChatGPT is currently missing part of a long conversation, rescanning may produce an incomplete snapshot. **Privacy** All scanning, keyword matching, highlighting, minimap generation, and cached snapshots are handled locally in your browser.
