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.

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.

Frequently Asked Questions

What does Alt+G do exactly?
Alt+G groups open tabs by their domain: all GitHub tabs go into one group, all Google Docs tabs into another. Pinned tabs, tabs without a URL, locked tabs, and Chrome internal pages are left alone, and a domain only becomes a group when it has at least two tabs. Groups are created using Chrome's native tab group API.
What does Alt+Shift+G do?
Alt+Shift+G ungroups every unlocked tab, returning most of the tab bar to a flat list. Locked tabs stay grouped.
Are groups collapsed when created?
No. When Alt+G creates groups, they start expanded by default. If you enable auto-collapse in Settings, new groups will start collapsed. Click any group to expand it and see its tabs.
Does Smart Tab Grouping work alongside Chrome's built-in tab groups?
Yes. It uses Chrome's native tab group API, so groups created by Smart Tab Grouping appear and behave identically to groups you create manually.
