I built a Chrome extension that summarizes articles in ~2 seconds using Groq's free LLaMA API.

The problem: I kept copying articles into ChatGPT to get summaries. Dozens of times a day. It felt like a workflow that should not exist.

The solution: Click an icon, get a summary. No copy-paste, no tab switching, no subscription.

Tech stack: - Chrome Extension Manifest V3 - Vanilla JS (no frameworks) - Groq API (free tier, LLaMA 3) - Mozilla Readability for article extraction - DOMPurify for sanitization

It has 36 customization combinations (4 tones x 3 lengths x 3 focus areas), smart caching, and costs nothing to run.

Happy to discuss the technical decisions or answer questions.
