  **ChatGPT History Deep Searcher** is a free Chrome extension for searching your ChatGPT conversation history.
  
  It helps you find past prompts, answers, code snippets, troubleshooting notes, and research discussions across your entire ChatGPT history. The extension uses ChatGPT’s own search page, lets you select matching conversations, then scans them locally and highlights every keyword match.
  
  **Key features**
  
  - Searches across your full ChatGPT history
  - Completely free to use
  - No account registration required
  - No database setup required
  - Does not connect to any third-party server
  - Simple search workflow
  - Select and scan multiple matching conversations
  - Highlight keyword matches inside conversations
  - Navigate results with a minimap and hit list
  - Local cache support to avoid repeated full scans
  
  All scanning and cached snapshots are handled locally in your browser. This extension is designed for users who have a large ChatGPT history and need a simple way to quickly locate specific past conversations.

  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.
  
  This extension:
  
  - Does not require registration
  - Does not require an external database
  - Does not connect to any third-party server
  - Does not sell or transfer your data
  - Does not use your data for purposes unrelated to the extension's core functionality
  
  **Version 1.0.1.4 updates**
  
  - Updated store description to include current-conversation scanning and the Conversation Navigator workflow.
  - Clarified local cache behavior and why cache is important for long ChatGPT conversations.
  - Documented the local in-snapshot search box, minimap, hit list, and cache protection workflow.
  - Included the latest scan failure handling improvement from version 1.0.1.3.
  
  **Previous 1.0.1.3 fixes**
  
  - Fixed an issue where the scan status popup could remain visible if ChatGPT redirected away from the conversation page or conversation content could not be found.
  - Improved current conversation scan behavior.
  - The extension is now only available when the current active tab is a ChatGPT page.
  - Release packaging now preserves previous zip packages in the dist folder.
