TabSentry - Project Story

The Problem

I couldn't find a tab management system that worked for me. Browser tabs were getting out of control, and existing solutions felt clunky and manual.

The Vision

I wanted to bring conversational tab management to Chrome - imagine controlling your tabs just by talking to them. At the same time, I wanted to learn more about Chrome's new Prompt API.

Development Journey

I programmed TabSentry myself under the guidance of my mentor, who helped brainstorm ideas, warned me away from approaches that wouldn't work, and steered me in the right direction. It was a collaborative learning experience.

Key Challenges

The biggest challenge was figuring out the best way to implement AI features. I initially explored both the Prompt API and Summarizer API, testing which would work better for my use cases.

What I Learned

The Prompt API proved superior for generating tags and translating natural language into function calls
How to architect conversational AI in a browser extension context
Extension development best practices and Chrome's permissions model
On-device AI capabilities and limitations

The Result

TabSentry (Alpha) - a tab manager where you can say "Close all entertainment tabs" or "Save my programming tabs for later" and it just works. All powered by Google's on-device Prompt API, keeping everything private and fast.

Currently in alpha development, exploring what's possible when tab management meets conversational AI.
