I built Scaffold to solve a problem I kept hitting: I wanted to embed AI features (chatbots, content generators) in my projects, but didn't want to manage API keys, build backends, or pay per request.

The approach: Instead of calling OpenAI's API, Scaffold generates optimized prompts that users send to ChatGPT themselves. You build a form with custom fields, write a prompt template using {{variables}}, and your users get a perfectly formatted ChatGPT prompt.

Why this works: - Zero infrastructure (no backend needed) - Zero API costs (free forever) - Works anywhere (iframe embed on any site) - Users control the AI interaction

What it can't do: - Conversational AI with memory (each submission is a new prompt) - Embedded responses (opens in ChatGPT, not your site) - Server-side processing (no programmatic access to responses)

Tech stack: Next.js 14, Supabase (auth + PostgreSQL), Vercel

Use cases: - Blog post generators - Email writers - Study tutors with specific knowledge (via "fixed fields") - Product finders

I'm 17 and this is my first real launch. Looking for technical feedback - what would make this a no-brainer for you?
