🚀 Installation
⚡ Quick Install (Recommended)
Just want to use it? Download and go:
- Download the latest release (
.zipfile) - Extract the zip to a folder
- Open Chrome → go to
chrome://extensions - Enable Developer Mode (toggle in top right)
- Click "Load unpacked" → select the extracted folder
- Done! Click the 🧠 icon to organize your tabs
⏳ First-time setup: The AI model (~23MB) downloads on first use. This may take 30-60 seconds depending on your internet speed. After that, it’s cached and instant!

The Clustering Engine
The heart of Grooopy is src/clustering.js — a production-grade implementation featuring:
- Agglomerative Hierarchical Clustering (HAC) with average linkage
- Multi-signal similarity scoring: semantic embeddings + domain affinity + URL patterns
- Adaptive thresholds that scale with tab count
- Smart singleton consolidation with multi-pass orphan handling
- Semantic name generation using TF-IDF-like scoring
