WhatTab is a Chrome extension that saves your open tabs into named groups, one per project, so you can close them all and get them back later.
Thirty-six tabs, five gigabytes, none of them readable. WhatTab parks the lot in one click and hands your laptop back — without asking you to sign up first.
We'll email you when beta opens — never more than once a month.

A trip you're planning. A purchase you're researching. A project you'll get back to. Closing the tabs feels risky, and bookmarks save one page at a time, not the whole task. WhatTab saves the whole set, then lets you close the window with a clear head.
It names the number, names the destination, and only then closes anything. Undo sits right there afterwards. Closing a pile of tabs usually feels risky. Here it isn't: you see exactly what will be saved before anything closes.
Pick the next workspace and WhatTab swaps the whole window for you. Anything you hadn't saved gets rescued into its own workspace on the way out — and it says so.
Fifteen loose tabs become three named workspaces you can rename, uncheck or split. Nothing saves until you say so — the AI proposes, it never rearranges your work behind your back.
Everything still open, itemised by the memory it's holding. This is the honest answer to "why is my laptop slow?" — and the button that fixes it sits at the top of the same list.
WhatTab snapshots your open tabs on its own, so a crash becomes a restore instead of a loss. Delete a workspace and it waits in Trash for 30 days — take back one tab or the whole thing.
Most tab managers want a login before they'll do anything, then take over your new-tab page. WhatTab opens from the toolbar, works offline, and lets you export the lot whenever you like.
WhatTab is a Chrome extension. It saves the tabs you have open into named workspaces (a workspace is a set of tabs for one project). You can then close them, search everything you've saved, and reopen a whole workspace when you need it.
WhatTab is in a private alpha with invited testers right now. Join the beta waitlist and we'll email you when the beta opens, never more than once a month.
No. WhatTab only closes tabs when you click Save & Close (or choose to close after an AI review), and it shows what will happen first. Undo appears right afterwards. It never closes saved tabs in the background.
No. Without one, everything stays in your Chrome profile on your computer. If you sign in (Google or email), your workspaces sync between your computers.
Only when you click Magic AI Group: the titles and web addresses of your open tabs, plus your existing workspace names. They go through our server to an AI service that suggests groupings. It never sees what's on the pages. Nothing is saved or closed until you approve the suggestions. If you never use it, none of your tab info is sent anywhere.
WhatTab keeps an automatic snapshot of your open tabs and offers to restore them the next time Chrome starts. Deleted workspaces and tabs go to Trash for 30 days, and you can restore them. This only works while the data is still on your computer, so use Settings → Export to JSON now and then as a backup.
