TabSense

Tabby is an AI-powered Chrome Extension that ends tab overload. It understands your tabs, finds what you need instantly, summaries idle ones, and speaks your language,smart, fast, and effortless.

🐾 About the Project – Tabby: Your Smart Browser Companion

💡 Inspiration

The idea for Tabby came from the frustration of managing 20+ open browser tabs.
The core question was:

“What if your browser could actually understand your tabs and help you create content within them?”

Tabby is built on a dual-layer strategy:

  • It features smart algorithms for reliable tab management.
  • It includes a fully integrated framework for four key AI APIs.

This ensures the extension provides immediate value while staying ready for advanced AI-powered features.

🛠️ How It Was Built

As my first Chrome extension, the initial challenge was understanding the Manifest V3 structure.
My main focus was designing a system that could securely and efficiently handle the four core AI services:

  • ✍️ Write API: Generates draft content.
  • 🔁 Rewrite API: Instantly paraphrases or changes tone.
  • 💬 Prompt API: Executes custom generative AI commands.
  • 📝 Proofread API: Performs quick grammar and spelling checks.

The API tokens are securely integrated into the background script, enabling authenticated requests even though full live testing is still in progress.
I relied heavily on online documentation and Gemini for guidance throughout the development process.

⚙️ Core Architecture

  • Popup Interface: User controls for search and quick actions.
  • Background Script: Manages tab data and events, runs smart algorithms, and acts as the secure message broker and API authentication layer.
  • Content Script: Injects editing functionality (Write, Rewrite, Proofread APIs) into the active tab’s context.

🧠 What I Learned

  • API Integration Complexity: Initially, I thought APIs would just “plug and play.” I learned how challenging it is to manage asynchronous data flow, secure token handling, and message passing between scripts.
  • Manifest V3 Mastery: Overcame the steep learning curve of Chrome’s new security model and script communication system.
  • Algorithmic Design: Built reliable, local features like contextual search and idle tab detection that ensure the extension works smoothly, even without active APIs.

⚡ Challenges Faced

  • Building a secure, asynchronous communication layer under Manifest V3’s strict security model.
  • Structuring how Content Scripts communicate with Background Scripts for external API calls.
  • Initial confusion on where to start, plus debugging permissions and event scripts during testing.

🚀 Current & Future Vision

✅ What Tabby Does Now

  • API Framework Complete: Write, Rewrite, Prompt, and Proofread APIs integrated and token-ready.
  • Smart Local Functionality:
    • Finds tabs by title or context.
    • Suggests closing idle or unused tabs.
    • Offers a clean, responsive interface.

🔮 What’s Next

  • Full live deployment and testing of all API features.
  • Automatic tab grouping and AI-based prioritization by content.
  • Integration with Gemini Nano for on-device, low-latency tasks.

🧮 Simple Technical Model

$$ \text{Tabby} = f(\text{Popup}, \text{Background}, \text{Content Script}, \text{4 AI APIs}) \Rightarrow \text{Smarter Browsing and Content Creation} $$
