TabFold AI

Drowning in duplicate tabs? You open a link and it's already open three windows over. You reopen the same Lucid, Figma, or doc library five times a day. TabFold AI fixes that, automatically.

Unlike every other "close duplicate tabs" extension, TabFold AI doesn't just match URLs. It uses Chrome's built-in on-device AI (Gemini Nano) to judge whether two tabs are really the SAME page, with a confidence level you control. When it's sure, it folds the out-of-focus duplicate away and keeps you on the tab you're actively using.

WHY YOU'LL LIKE IT
- Understands pages, not just URLs, so it catches duplicates other tools miss.
- You set the confidence: one slider, strict or eager. It is a hard floor.
- Fully on-device: no accounts, no servers, nothing leaves your machine.
- Keeps the tab you're on: it folds the out-of-focus copy, not the one you're using.
- Corrects itself: tell it "Not a match" and it learns, or "Ignore site" to allowlist a domain or a specific page.
- See the work: a live activity panel shows every check, its confidence, and the actual URLs.

HOW IT WORKS
1. A tab loads. TabFold AI checks it against your open tabs.
2. Exact and near-exact URLs fold instantly (tracking and locale params, #anchors, www, and trailing slashes are ignored).
3. If URLs differ, on-device AI compares titles, metadata, and optionally page text for a same-page probability, then discounts it by URL structure so different sub-pages stay separate.
4. Clears your confidence level? The out-of-focus duplicate folds away and you stay on your tab. Got one wrong? Hit "Not a match" and it learns.

100% ON-DEVICE, PRIVATE BY DESIGN
Everything runs locally via Chrome's built-in AI. No telemetry. No tracking. No ads. No network calls. Your settings and learning stay in your browser.

Requires Chrome 128+ with built-in AI. Works with URL matching even without it.
