ChatShelf — Search your AI chats

Search every message across ChatGPT, Claude, Gemini and Grok. Folders, prompts, bookmarks, export — all stored locally.

Native search on ChatGPT, Claude, Gemini and Grok only looks at conversation titles. ChatShelf indexes every message, so you can find the answer you remember but cannot name. SEARCH • Full-text search across all four assistants at once • "quoted phrases", -excluded words, and prefix matching • Filter by platform, topic, folder, message author or date range • Results group by conversation, with the matching text highlighted • Ctrl+Shift+F opens a search overlay on any chat page • Accents fold, and Japanese and Chinese are indexed properly ORGANISE • Nested folders that can hold chats from all four assistants together • Smart tags label each chat by topic automatically, on your device • Bookmark any message with a note, from any of the four sites • Bulk-select conversations to file, export, archive or delete them WRITE FASTER • Save prompts with {{placeholders}} you fill in as you insert them — type // • Chain up to ten prompts and run them in sequence — type .. • Reference a past conversation as context in a new one — type @@ • Ctrl+K opens a command palette for everything KEEP AN EYE ON THINGS • A context-window meter warns before a long thread stops working • Live word and character counts on every message • Collapse long messages, or all of them at once • Daily usage, a year heatmap, and streaks EXPORT AND BACK UP • TXT, Markdown, JSON or ZIP • Markdown carries YAML frontmatter for Obsidian and Logseq • A ZIP mirrors your folder tree, so a backup keeps its structure • Every format links back to the original conversation PRIVACY There is no ChatShelf server. Your conversations are indexed into your own browser's storage and never leave your machine. No analytics, no telemetry, no third-party code. "Erase" in the popup clears everything instantly. ChatGPT works as soon as you install. Claude, Gemini and Grok are optional — the extension has no access to them until you switch them on, and switching one off removes the access again. Works on Chrome, Edge, Brave and Arc. ChatShelf is an independent extension and is not affiliated with or endorsed by OpenAI, Anthropic, Google or xAI.
