One shortcut to search back every AI conversation you've had
Threadback is a fully local browser extension: open a search overlay with a shortcut or the right-click menu, or type "tb" + Space + your keywords in the address bar, and instantly search your synced history across major AI platforms — ChatGPT, Claude, Gemini, DeepSeek and more. Organize with folders & tags, and export anytime. Conversations, queries, and the index all stay on your device. Nothing is uploaded.
Supported platforms
Platform APIs change often — we continuously maintain and update the adapters so search keeps working; new platforms stay just as fully local.
Why Threadback
Fully local
Conversations and the index live in your own browser. Search offline, never uploaded.
Search from anywhere
A shortcut, the right-click menu, or "tb" + Space + your keywords in the address bar — open search anytime, without breaking your flow.
Keyword + semantic search
Match exact keywords, or find a chat by meaning when you can't recall the wording.
Organize & export
Sort chats into folders, tags and smart collections; export anytime to keep or migrate.
Privacy is the baseline, not a feature
Threadback never collects, stores, or forwards any conversation, search query, or usage statistics. There are only two kinds of outbound request: a one-time download of the local model when you enable semantic search (model files only), and the Pro license check when you activate / validate Pro (only a License Key and an anonymous device id).
