Smart Tab Grouping — Auto-Group by Domain
Press Alt+G to group open tabs by domain, leaving pinned tabs alone. Groups stay expanded unless auto-collapse is on in Settings. Undo with Alt+Shift+G.
Updated
Smart Tab Grouping organizes a chaotic tab bar into tidy, collapsible groups with a single keystroke. Press Alt+G and your open tabs are grouped by domain: all your GitHub tabs together, all your research tabs together, all your Google Docs together. Pinned tabs are skipped, along with tabs without a URL, locked tabs, and Chrome internal pages, and a domain only becomes a group when it has at least two tabs. New groups stay expanded by default; you can enable auto-collapse in Settings if you prefer them collapsed.
How It Works
Alt+G triggers a scan of all open tabs. Tabs sharing the same domain are placed into a Chrome native tab group, assigned a color, and labeled with the domain name. Pinned tabs are skipped, along with tabs without a URL, locked tabs, and Chrome internal pages, and a single tab does not form a group. The grouping uses Chrome’s built-in Tab Groups API, so the result looks and behaves identically to groups you’d create by hand.
When Alt+G creates groups, each group is expanded by default — showing its colored label and tabs in the tab bar. Your tab bar stays readable no matter how many groups exist. You can enable auto-collapse in Settings to have new groups start collapsed instead.
To undo grouping, press Alt+Shift+G.
Settings
| Option | Default | Description |
|---|---|---|
| Alt+G shortcut | Active | Groups open tabs by domain (pinned tabs, tabs without a URL, locked tabs, and internal pages are skipped); newly created groups are expanded automatically (unless auto-collapse is enabled) |
| Alt+Shift+G shortcut | Active | Ungroups every unlocked tab at once; locked tabs stay grouped |
When to Use This
Research sessions that sprawl: You’ve been jumping between Wikipedia, Reddit, and several documentation sites and your tab bar is a mess. Alt+G brings order in one keystroke.
Before saving a workspace: Use Smart Tab Grouping to organize tabs by domain, then save the result as a named Workspace. The groups are preserved in the workspace.
Routine cleanup: At the end of a work session, Alt+G clusters what’s open by domain so you can quickly identify which tabs belong to which project before deciding what to close or save.
Reducing visual noise: Turn on auto-collapse in Settings and new groups start collapsed, so you see only color-coded labels until you expand one. It’s a small change with a noticeable effect on focus.
Privacy
Smart Tab Grouping reads tab URLs locally to extract domain names for grouping. No URL data or browsing patterns leave your device.
