Smart Tab Groups

Smartly group tabs, cleanup duplicates, close stale tabs, and save/restore workspaces.

Smart Tab Groups is the ultimate Chrome extension designed to solve the "100+ open tabs" problem and declutter your online workspace. Built on Manifest V3, it organizes your browser dynamically, reduces memory footprint, and helps you stay focused on what matters. Core Features: 1. 📂 Smart Tab Grouping (Offline Heuristics): Instantly classify and sort open tabs into structured, color-coded groups based on intelligent domain and keyword heuristics. Standard categories include Coding, College/Research, YouTube/Media, Shopping, and Social. 2. 🧹 Duplicate Tab Cleaner: Scan active windows to detect duplicate instances of the same URL. Merge and close clones in one click to reclaim browser memory. 3. ⏳ Stale Tabs Inactivity Filter: Identify and close background tabs that have been idle past a custom threshold (e.g., 1 hour, 2 hours, 1 day). 4. 💾 Session Workspaces (Save & Restore): Capture and persist the active state of all your current tabs and groups as a "Workspace". Close your browser with confidence and restore your entire tab layout in a single click whenever you're ready. 5. ⚙️ Custom Categorization Rules: Add personal rules mapping specific domains directly to your favorite categories. Keep your browser clean and fast with Smart Tab Groups!
