CASL (Context-Aware Smart Linker) is a Chrome Extension that provides instant, AI-generated explanations for any highlighted text — without leaving your current tab.

🎯 The Problem

Modern browsing is broken:

You encounter unfamiliar terms, libraries, people, or jargon

You open them in new tabs “to check later”

Tabs pile up → focus breaks → productivity drops

💡 The Solution

CASL eliminates search detours by answering in place:

✨ Key Features

🤖 LLM-Powered (Groq) Fast, cheap inference using LLaMA-3 via Groq API
