Smart Regroup

The core feature of TabIt. Click Smart Regroup to automatically organize all your open tabs into meaningful groups.

Under the hood, TabIt:

1. Scores tab similarity using TF-IDF on titles and URLs
2. Builds a k-nearest-neighbor graph of tab relationships
3. Runs the Leiden community detection algorithm to find clusters of related tabs
4. Names each group using keyword extraction from tab titles
5. Creates Chrome tab groups with the results

Existing tab groups are preserved — Smart Regroup integrates new ungrouped tabs into existing groups or creates new ones as needed.

Customize Before Grouping

Click Customize to adjust parameters before running Smart Regroup:

• Tab Range — Set the minimum and maximum number of tabs per group (1–20). Clusters smaller than the minimum are treated as outliers and left ungrouped.
• Granularity — Choose between three presets:
  • Few Groups — Fewer, larger groups
  • Moderate — Balanced grouping (default)
  • Many Groups — More, smaller groups

Auto Grouping

Enable Auto Grouping from the popup to have TabIt automatically organize new tabs as you browse.

When enabled:

• New tabs are analyzed and placed into existing groups or new ones after a short debounce (3 seconds)
• Existing groups are frozen — their tabs stay in place
• If a grouped tab navigates to a domain that no longer matches its group, it gets ungrouped and re-clustered
• Uses incremental Leiden clustering for efficiency

Toggle auto grouping on or off at any time from the main popup.

Group Management

Each tab group in the popup supports:

• Rename — Click the menu icon on a group, then select “Rename” to edit the group name inline. Press Enter to confirm or Escape to cancel.
• Change Color — Pick from 9 colors: grey, blue, red, yellow, green, pink, purple, cyan, and orange.
• Ungroup — Dissolve a group, returning its tabs to the ungrouped state.
• View Tabs — Click a group to expand it and see all its tabs, sorted by most recently accessed.
• Activate Tab — Click any tab in the list to switch to it.

Domain Coherence

When auto grouping is active, TabIt monitors grouped tabs for domain changes. If a tab navigates to a URL whose domain no longer matches its sibling tabs, TabIt automatically ungrouped it and re-evaluates its placement. This keeps groups coherent as you browse.

Internationalization

TabIt supports multiple languages:

• English (default)
• Japanese (日本語)
• Spanish (Español)

Change the language in Settings.
