🧠 I Built an AI-Powered Chrome Extension That Groups Your Tabs Automatically

Hey devs! 👋
I’m Abhishek, a CS student and dev who constantly ends up with way too many tabs open.
Last week, I had 22 tabs open — half were work, half were random Google rabbit holes. Finding the right one was a nightmare.

That’s when I thought:

“What if my browser could understand what each tab is about and automatically group them for me?”

So… I built exactly that. 🚀

💡 What My Extension Does

It’s a Chrome extension powered by AI (Gemini API) that groups your open tabs smartly based on context.

Let’s say you have:
5 tabs about React tutorials
3 tabs about news
2 YouTube videos

You just click one button — and boom, it creates tab groups like “Web Dev”, “News”, and “Entertainment” automatically.

No manual organizing. No chaos. Just clean, grouped tabs. 🙌

⚙️ How It Works (in simple terms)

The extension collects your open tab titles and URLs.
It sends them to a small backend server I built with Node.js + Express.
The backend calls Google’s Gemini AI to analyze and group similar tabs.
Chrome’s API then creates tab groups automatically based on the AI’s response.
All of this happens within seconds!

🧰 Tech Stack

Frontend: Chrome Extension (Manifest V3 + JavaScript)
Backend: Node.js + Express
AI Model: gemini-2.0-flash-001
Hosting: Render (free-tier)

🔐 Privacy

No user data is stored.
The tab info (title + URL) is sent securely to the AI only for grouping and then discarded immediately.

🌍 Try It Yourself

👉 Install from Chrome Web Store

🚀 What’s Next?

I’m planning to add:
Custom grouping options
Tab summary + insights

Would love feedback or ideas from fellow devs — what do you think could make this even better?
