Tabby

Inspiration

Have you ever opened so many tabs that your browser turns into a chaotic mess each one too important to close, yet impossible to navigate? That’s exactly what inspired us to create Tabby.

We wanted to build something that could bring clarity to that chaos, an intelligent browser companion that summarizes your open tabs and groups them based on similarity. Because information overload shouldn’t stop you from working efficiently.

What it does

Tabby is a browser extension that summarizes and groups your open tabs intelligently. It:

Summarizes each tab so you don’t have to reopen it just to remember what it was. Let's you group similar tabs together and colour them for visiual organization. Groups similar tabs automatically (for example, all research articles or all YouTube tabs). It’s simple, fast, and designed to bring calm to your chaotic workspace. Choose your summary style, whether you want a short, brief, long, or detailed summary, Tabby customizes it according to your choice.

How we built it

We built Tabby as a browser extension using:

HTML, CSS, and JavaScript for the core structure

Chrome.TabGroupsAPI for managing and organizing browser tabs

Gemini API for generating smart and concise tab summaries

Gemini 2.0 flash API to powers our tab summarization feature. The extension runs directly in your browser and interacts with all your open tabs through these APIs.

Challenges we ran into

The hardest part was grouping similar tabs together automatically, it required analyzing tab content and titles in a meaningful way. Getting accurate summaries without long delays was another big challenge.

Accomplishments that we're proud of

We made a clean, easy-to-use extension that actually solves a real everyday problem. Watching dozens of chaotic tabs turn into organized groups in one click felt like magic. We face this problem daily, so removing that chaos with one click and not losing any valuable information felt like a huge accomplishment and relief.

What we learned

We learned how to integrate AI APIs (like Gemini) effectively within browser environments.

We discovered the power of Chrome’s TabGroupsAPI, which most people don’t realize can be automated.

Most importantly, we learned that user simplicity matters more than technical complexity — a good tool should feel effortless.

What's next for Tabby

We want to add:

Cloud sync across devices

AI-based “smart suggestions” for which tabs to close or save

Integration with note-taking apps for long-term storage
