WordSense AI is a lightweight, zero-latency Google Chrome extension engineered for context-aware reading. Simply highlight any word or multi-word phrase on any webpage—including highly secure developer platforms like GitHub, Medium, or dev.to—and WordSense instantly displays a concise, one-sentence AI-generated definition tailored strictly to your selected knowledge domain profile.
🚀 Key Features
- ⚡ Zero-Latency Streaming: Renders real-time definition outputs chunk-by-chunk using a typewriter streaming interface at 500+ tokens per second.
- 🎯 Domain-Specific Context Tuning: Toggle seamlessly between specialized knowledge profiles including General, Science, Medical, Law, Computer Science, and Architecture, or define custom parameters.
- 🛡️ Content Security Policy (CSP) Bypass: Engineered to run smoothly across highly secure web environments by routing all external cloud handshakes through an isolated background service worker layer.
- 🔋 Leak-Proof Resource Management: Employs an internal
AbortController pipeline to instantly cancel active backend API requests the moment a user deselects text, clicks away, or switches browser tabs.
- 🎨 Premium Glassmorphism Interface: Features an ultra-lightweight, visually elegant floating tooltip overlay that matches modern dark-mode aesthetics without breaking page layout grids.
🛠️ Technical Architecture & Stack
Frontend (Chrome Extension Framework)
- Manifest V3 Core: Complies fully with modern security guidelines using non-persistent background service workers.
- Vanilla JavaScript: Zero third-party dependencies to maintain a near-zero performance footprint.
- DOM String Injection Mitigation: Renders incoming stream chunks strictly as passive text nodes (
textContent), eliminating remote code injection risks.
- Chrome Storage Sync: Persists user application toggles and active knowledge domains securely across device profiles.
Backend Infrastructure
- Flask Engine (Python): Lightweight micro-routing container optimized to handle asynchronous server-sent event loops.
- Groq LPU Integration: Communicates with Meta's Llama models over Groq's high-speed inference layer to deliver instantaneous results.
- CORS Compliance: Configured with specific cross-origin allowance rules to handle background extension pings.
