Tabs?
What tabs.

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.

Why tabs pile up

Do you keep tabs open “just in case”?

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.

Workspace = a named set of tabs for one thing you're working on, like “Apartment Hunt” or “Taxes.” Save it, close it, reopen it any time.
Five things it does, in order No account needed to get started
01 · Save & Close

One click parks the whole pile.

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.

02 · Switch projects

Change project, not windows.

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.

03 · Magic AI Group

AI drafts it. You sign off.

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.

The panel that shows the bill.

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.

05 · Recovery & Trash

Even a crash is just a restore.

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.

Why it isn't like the others

No account needed to get started.

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.

No account wallInstall it and start saving right away — no sign-up screen first. Sync is optional.
No new-tab takeoverYour new tab page stays yours. WhatTab lives behind the toolbar icon.

Questions

Frequently asked

What is WhatTab, in plain words?

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.

When can I try 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.

Will it close my tabs without asking?

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.

Do I need an account?

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.

What does the AI see?

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.

What if Chrome crashes, or I delete something by mistake?

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.

What if I have a question that isn't here?

Email support@whattab.com. Every note gets read.
