You have a group of tabs for something you haven’t finished yet. You shouldn’t have to choose between leaving it open forever or losing it when you close Chrome.
What Tabnook is built around

Close it, keep it

Closing a group doesn’t lose it.

Close a group and it moves to your saved list. One click brings the tabs back, grouped and named, shown as the site the way Tabnook stores them. Try it.

What Tabnook does

Everything that belongs with tab groups but isn’t built in yet

Groups that persist, automatically

Every group is tracked from the moment it’s created and saved continuously. Close a group and it moves to your saved list. One click to reopen it, and your tabs come back grouped, named, and colored exactly as you left them.

Notes that stay with the URL

Attach a note to any tab or group. The note is keyed to the URL, so it survives close, reopen, and restart. Close the tab, come back next month, the note is still there. Search finds all of it.

Snooze a group, bring it back on schedule

Close a group for now and bring it back at 8am, 2pm, or a custom time you pick. The group reopens on schedule even if Chrome was closed in between. Works on a single tab or a whole group.

One search across everything

One search bar covers open tabs, saved groups, tab notes, and group notes. Click a result to jump to the tab or reopen the group. You don’t have to remember which group something was in.

Side panel, not a new tab page

Tabnook lives in Chrome’s native side panel so you can see your groups and your open page at the same time. No new tab page takeover. No extra window to manage.

Local by design, not by accident

Everything is stored in your Chrome profile on your machine. Tabnook makes no external network requests, no telemetry, no analytics, no remote code. By default it saves only the site name for each tab, not the page title or URL path.

One bar, four kinds of thing

Search across tabs, groups, and notes at once.

Open tabs, saved groups, tab notes, group notes. Type and everything that matches shows up with a label saying where it lives. You don’t have to remember which group it was in. Try “pasta”, “client”, or “80”.

    Who it’s for

    People who can’t close a group without losing something

    The researcher

    Four active investigations running at once. Needs to close one, come back to it in three days, and find it exactly as it was, with the note about which thread to follow up on.

    The developer

    Project group open for a full sprint. Closes Chrome on Friday, opens it Monday, and wants the same twelve tabs back, stored locally and ready without having to think about it.

    The freelancer

    Four client contexts that need to be completely separate. Closes one client, opens another, and the notes from the last Client A session are waiting when they return to it next week.

    The deep reader

    Working through a 14-tab research thread over several days. Doesn’t need it open right now, but needs it back Saturday morning exactly where it was. So they snooze it and it comes back on schedule.

    Bring it back on schedule

    Snooze a group and it returns when you said.

    Close it for now and pick a time. The group comes back on schedule, grouped and ready, even if Chrome was closed the whole time.

    Local by default

    Your groups, notes, and snooze schedules live in your Chrome profile. Tabnook makes zero external requests. Only your preferences sync, through Chrome’s own sync channel. Your tab data never does.
