Tabitha

Tabitha replaces your new tab page with a workspace for people who keep too many tabs open. Save whole windows for later, reorganize them by drag-and-drop, and instantly find anything you've saved — with optional AI that summarizes pages, groups them by topic, and answers questions about your own research. YOUR NEW TAB WORKSPACE (works fully offline, no account, no sign-in) • Every new tab opens Tabitha — your hub for open and saved windows • Save entire windows and restore them later • Reorganize tabs and windows with drag-and-drop • Remove duplicate tabs in one click • Automatic session snapshots so you can reopen tabs after a crash • Backups you control — save all your data to a file and restore it anytime AI FEATURES (optional — you choose where they run) • Page summaries: get a short summary of any saved page • Semantic search: search by meaning across the content of your saved tabs, not just titles and URLs • Auto-organize: automatically group saved tabs into topic-based windows • Chat: ask questions about your saved research and get answers with citations Run AI on this device: open models (Google's Gemma 4 E2B and EmbeddingGemma 2) run in your browser, so your pages and questions never leave your computer. Needs a WebGPU-capable graphics card, 16 GB of memory, and a one-time 3.4 GB download; Tabitha only offers it where your computer can run it. Or use Google Gemini: faster and works on any computer, with your own free Gemini API key. Page text is sent directly from your browser to Google. PRIVATE BY DESIGN • Everything is stored locally on your device — there is no Tabitha server • No analytics, no tracking, no ads • AI is strictly opt-in, and nothing is chosen for you: on-device AI keeps your pages on your computer; Gemini sends them only to Google, using your key • Your API key is stored locally and is never included in backups Tabitha's core workspace is completely free to use and works without any API key or account. On-device AI is free too; Gemini needs a free Google Gemini API key that you provide. Toolbar shortcut: click the Tabitha icon (or Ctrl+Shift+K / Cmd+Shift+K) to search your tabs or open the workspace from any page.
