Smart Tab Grouping — Auto-Group by Domain

Smart Tab Grouping organizes a chaotic tab bar into tidy, collapsible groups with a single keystroke. Press Alt+G and every open tab is grouped by its domain — all your GitHub tabs together, all your research tabs together, all your Google Docs together. Inactive groups collapse automatically so only the group you’re using takes up space.

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. The grouping uses Chrome’s built-in Tab Groups API, so the result looks and behaves identically to groups you’d create by hand — they appear in the Vertical Tabs side panel, sync with Chrome, and work with all standard Chrome group features.

When Alt+G creates groups, each group is collapsed by default — showing only its colored label in the tab bar. Your tab bar stays readable no matter how many groups exist. Expand any group to see its tabs.

To undo all grouping, press Alt+Shift+G. Every group is dissolved and tabs return to an ungrouped flat list.

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 topic, 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: 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.
