TabsMaster Chrome extension is out on the Chrome Web Store.
- An AI summary on every tab, so you still know what it was months later
- AI groups you describe in plain English, sorted for you automatically
- One search box across your open tabs, your bookmarks and your entire history
- Parks idle tabs to win the memory back, and refuses any tab you've typed in
- Finds duplicates, dead links, and pages nobody has touched in years
Built and tested on a browser holding 1,131 tabs. More on each of those below.
SEARCH — one box, three sources
Type two characters and it searches the title, URL and AI summary of every open tab, plus your bookmarks and your browsing history, each in its own section.
SEARCH — one box, three sources
Type two characters and it searches the title, URL and AI summary of every open tab, plus your bookmarks and your browsing history, each in its own section.
History is searched over all of it, not Chrome's default 24-hour window. That's the difference between finding the article you half-remember from last year and not finding it.
Results are de-duplicated across all three. If a page is open, bookmarked and in your history, you see it once, as the open tab, instead of three times in three places.
AI SUMMARIES — what was this tab, again?
Cloudflare renders the page, Gemini condenses it to 25 words or fewer, and the result is cached permanently. It survives the tab being closed, so something you shut in March is still described in October, and still searchable.
AI GROUPS — describe it, don't configure it
Type "AI tools for legal work" and Gemini reads every tab and decides which ones belong. The group becomes a filter chip across the top, and each matching tab gets a badge. The chip tells you the group has 30 tabs; the badge on a row tells you why that tab is one of them.
New tabs sort themselves about eight seconds after they load, so groups stay current without you touching them. One call judges 25 tabs against every group at once, so a few hundred tabs cost a handful of requests rather than hundreds.
Change a rule later and the old verdicts are cleared rather than kept. They were judged against wording that no longer exists, and a stale verdict quietly filtering your inventory is worse than a tab showing up unsorted.
DUPLICATES — exact, and same-domain
Both group by the duplicate rather than by the window, because copies of a page almost always live in different windows, and grouping by window scatters the exact thing you're trying to compare. Each header tells you how many copies there are and how many you could close.
Same-domain groups deliberately don't suggest a number to close. Those are different pages, and telling you to close them would be advice to throw away real tabs.
SUSPENDING — without losing anything
The tab keeps its real title and favicon and comes back when you click it. The placeholder shows a screenshot of the page, its summary, and how long it's been sitting there.
It watches for real keystrokes rather than guessing, so a half-written comment never gets thrown away, and it tells you which tabs it refused and why. Pinned tabs and anything playing audio are left alone. Alt+Shift+S parks the one you're on; or select a batch, or let the idle timer handle it.
THE SMALLER THINGS THAT ADD UP
- Already using another suspender? It decodes their parked tabs back to the real URL and title, so your list shows actual pages instead of a wall of placeholder links.
- The dead-link scan separates genuinely dead from merely blocked. Plenty of live sites reject an automated request, and calling those dead would be wrong.
- Every bulk job says what it skipped: "Summarising 258 of 528 selected, skipped 190 already summarised, 74 not web pages, 6 repeats of the same URL."
- Real last-updated dates for GitHub repos and habr.com articles, read from the public feed with no token and no rate limit. Amber past a year, red past two.
- Sort by when you last touched a tab. No scan needed, covers everything.
- Hover any row for a screenshot of the page.
- Full session save and JSON export, so a crash doesn't cost you everything.
YOUR DATA STAYS YOURS
The AI features run on your own Gemini and Cloudflare keys. No account, no analytics, no server belonging to anyone else. Without keys, everything except the summaries still works.
