Everything a tab hoarder needs

One extension for tabs, memory & focus

Save sessions, reclaim RAM, and find any tab in seconds, without losing your place.

Save & restore sessions

Capture a whole window, tabs, groups, names and colors, and bring it back in one click, in a new window or the current one.

Suspend to free memory

Unload idle tabs to reclaim RAM, or auto-suspend after a set idle time.

Groups, folders & tags

Organize sessions into folders, tag them, and keep tab groups intact.

Instant search

Search across every saved session and tab, by title or URL.

Auto-save & recovery

Closed windows are auto-saved and recovered even after a crash.

Share links & team spaces

Send a session as a private link that expires on its own and can be revoked any time, or work in a shared space with your team.

Workspaces

Keep work, study and the side project apart. Switch between them and the popup follows, and your tabs stay exactly where they are.

Focus Mode

Send one tab fullscreen and leave the rest behind. After a long unbroken stretch on a page, NestarioTabs quietly offers it.

AI that does the tidying Pro

Name a session from what is in it, group loose tabs by what they are about, and search your library by meaning instead of exact words.

Questions

Frequently asked

Is NestarioTabs free?

Yes. Saving, restoring, suspending, groups, folders, tags, search and sharing are free with unlimited local storage. Pro adds cloud sync and backup; Team adds shared workspaces.

How does suspending tabs free memory?

Suspending unloads an idle tab from memory while keeping it in your window. Click it to reload instantly. You can also auto-suspend tabs after a set idle time.

What happens to my tabs if I uninstall?

Your saved sessions live on your device, so uninstalling the extension removes them with it. Pro keeps a copy in the cloud, which is what carries your sessions to a new browser or a new machine.

Are my tabs private?

Yes. Sessions are stored on your device by default, and signing in is optional. It is only needed for cloud sync, Teams and the Pro AI features. A share link is unlisted and expires on its own, and you can revoke it at any moment. We never sell your data and never run trackers.

What do the AI features do, and what do they see?

The AI can name a saved session from what is in it, group loose tabs by what they are about, and find a session by meaning rather than exact wording. It is powered by a third-party API, which receives the titles and web addresses of your saved tabs. Page contents, cookies and form data are never sent. It is a Pro feature, so nothing leaves your device on the free plan.

What are AI credits?

Each AI action costs a credit or two, and Pro includes 300 a month, enough for everyday use. A Team pools 300 per seat across everyone. You are only charged when the AI actually answers: a repeated request served from cache, or one our own code handled, costs nothing. If you run out you can buy more, and they never expire.

Which browsers are supported?

Chrome, Edge, Brave, Opera and Vivaldi via the Chrome build, plus Firefox.

Can I import from OneTab or Session Buddy?

Yes. NestarioTabs imports your existing sessions from OneTab and Session Buddy in a couple of clicks, nothing gets left behind.
