Profile Intelligence: Scrapes profiles (professors, professionals, companies) and lets you chat with the LLM to ask "Am I a good fit for their research project?" Page Summarizer: Instantly summarizes any webpage and answers questions about the content—perfect for research papers, documentation, or Wikipedia articles. It can also scrape content of notes, classes, workflow and can generate you custom quizes or materials as you say , can also make game without the interface, it doesn't need interface , it will chat with you and store your context where ai can never forget.

How we built it

Frontend: JavaScript (Chrome Extension, Manifest V3) Backend: Python with FastAPI Web Scraping: Crawl4AI for clean markdown extraction Database: Neo4j graph database for conversation memory and relationships LLM: Claude Sonnet 4 for intelligent message rewriting and chat

Challenges we ran into

This was my first time building a Chrome extension—and my first time writing JavaScript. Integrating content scripts, background workers, async Python, Playwright on Windows, and Neo4j was a steep learning curve, but I made it work.
