Tabrief

Summarize any page, and never lose a tab to an accidental close or a crash.

Tabrief has two jobs: it summarizes what you're reading, and it makes sure you never lose a tab. SUMMARIZE ANYTHING Click Summarize on any page — an article, a Terms of Service page, a privacy policy, even a PDF opened directly in Chrome — and get a plain-language summary in seconds. Works fully offline with a local, extractive summary, no account or setup required. Want more? Add your own Anthropic or OpenAI API key in Settings for a true AI-generated rewrite of the page in plain English. Legal pages get special treatment: instead of a generic summary, you get grouped bullet points covering the parts people actually care about — data sharing, fees, your rights and limits, and how to cancel. NEVER LOSE A TAB - Save: one click to bookmark any tab you want to keep, no folders or typing required. - Session Backup: runs automatically in the background, keeping a running snapshot of every open tab — so if Chrome crashes, your computer restarts, or you close something by accident, you can reopen everything from the Saved page. - Undo: closed a tab by mistake? Undo it instantly from the toast that appears. STAY ORGANIZED Every tab is automatically sorted into a category — Work, Mail, Shopping, Finance, Travel, Video, Social, Reading, Search, or Agreements — using local URL matching only. No AI, no network call, nothing leaves your browser for this. PRIVACY BY DESIGN Everything is stored locally in your browser. The only network requests Tabrief ever makes are the optional AI-rewrite calls, sent directly to the provider you configure, only when you explicitly click to use them. Nothing is read, summarized, or sent anywhere until you ask for it. Free. No account required. No tracking.
