Chrome extension · Side panel
You have twelve tabs
open for a reason.
Tabnook remembers
what that reason was.
Groups, notes, snooze, and search, all in Chrome’s side panel. Close a group tonight and reopen it next week with your notes intact. Nothing leaves your browser.

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.
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.
Local by default
No account. No server. Nothing leaves your browser.
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.
