Inspiration

If you've ever done a hackathon, you know the feeling. You just finished building something cool, but now you have like 30 minutes to make a demo video. You're sitting there staring at nothing, trying to figure out what to say and how to make it sound good. I built DemoScript to solve that problem for myself and every other hacker out there.

What it does

DemoScript looks at your GitHub repo and writes a 2-minute demo script for you. You just paste your repo URL, click a button, and it gives you a full script with a hook, problem, solution, features, tech stack, and a closing. Ready to read and record.

How I built it

Frontend: React with Vite and Tailwind CSS
Backend: Express.js server that talks to GitHub and handles the AI stuff
AI: Google Gemini API (gemini-2.5-flash) reads through your codebase and actually understands what you built
Smart Analysis: It pulls your README, package.json, and source files to get the full picture

Challenges I ran into

Hit Gemini API quota limits and had to try different model versions until one worked
Getting the prompt right so the scripts sound like a real person talking, not a robot
Making sure the script length actually fits in 2 minutes when you read it out loud
