About TabsMaster
1,131 tabs. 88 windows. Still nothing is lost.
TabsMaster turns an unmanageable browser into a searchable inventory - every tab in every
window on one screen, with AI summaries that tell you what each page actually was, months
after you forgot why you opened it.
── SEE EVERYTHING ──────────────────────────
• Every tab, every window, one list. Title and URL on a single line, sorted by when you
last touched them.
• Search across titles, URLs and AI summaries at once. Type two characters and it searches
your bookmarks and history too, de-duplicated against what you already have open.
• Find duplicates - exact matches and same-domain clusters - grouped so you can see which
copy to keep.
• Dead-link scan with a status per tab, and real "last updated" dates for GitHub repos and
habr.com articles, so a stale tab is obvious at a glance.
── SUSPEND, WITHOUT LOSING ANYTHING ────────
• Park idle tabs and get the memory back. The tab keeps its real title and favicon; the
page comes back when you click it.
• One tab, a whole selection, or automatically on an idle timer you choose.
• Alt+Shift+S parks the tab you are on. So does the toolbar panel and the right-click menu.
• A parked tab shows a screenshot of the page and its AI summary, so you recognise it
without loading it.
• It will not park a tab with unsaved text in a form. It watches for real typing, so a
half-written comment is never thrown away - and tells you when it refuses.
• Never-suspend list for the sites you always want live. Pinned tabs, playing audio and the
tab you are looking at are always left alone.
── LET AI DO THE SORTING ───────────────────
• One-sentence summaries, written to be recognisable months later. Cached forever, and they
survive the tab being closed.
• Describe a group in plain language - "AI skills for legal work" - and Gemini sorts every
tab into it. Each group becomes a filter chip.
• Jobs always say what they skipped and why. "Summarising 258 of 528 selected - skipped 190
already summarised, 74 not web pages, 6 repeats of the same URL." Never a progress bar
that looks like it lost your work.
── IT IS YOUR DATA ─────────────────────────
• No TabsMaster server. No analytics. No telemetry. No account.
• Everything is stored on your machine.
• AI features use YOUR OWN Google Gemini and Cloudflare keys, and run only when you have
entered them. No keys, nothing leaves your computer.
• Crash recovery: your whole session is saved continuously and can be exported to JSON or
restored tab by tab.
── FOR PEOPLE WITH TOO MANY TABS ───────────
Built for browsers with hundreds or thousands of tabs open, where the tab strip stopped
being useful a long time ago. If you keep twelve tabs, you do not need this. If you keep
twelve hundred, nothing else will show you what you actually have.
Requires your own API keys for the AI features; everything else works
without them.
