Inspiration

Building MVPs quickly can feel overwhelming — especially during hackathons or early idea validation. We wanted to help makers skip the boilerplate and instantly generate a ready-to-use Bolt.dev prompt just by describing their idea in plain language.

What it does

OnePrompt MVP Builder takes in three short inputs:

  • Who you're building for (persona)
  • The problem they're facing
  • How you plan to solve it

It then generates a complete, structured Bolt.dev prompt — including LLM or audio detection, API key placeholders, and even badge boilerplate — so users can paste it directly into Bolt.dev and instantly prototype their idea.

How we built it

We used:

  • HTML, TailwindCSS, and vanilla JavaScript for the frontend
  • Prompt templates and simple logic to detect the need for LLM or audio features
  • A dynamic output field that formats the final prompt in real-time
  • A fixed-position Bolt.new badge with hover effects and mobile responsiveness

Challenges we ran into

  • Making the output flexible enough to handle different project types while still being structured
  • Detecting when to include features like audio narration or API key placeholders without overcomplicating the UI
  • Ensuring a delightful experience on both desktop and mobile

Accomplishments that we're proud of

  • Turning plain-text input into a fully-structured MVP prompt with almost zero friction
  • Helping non-technical users feel empowered to launch
  • Meeting all the Bolt.dev hackathon requirements elegantly

What we learned

  • Less is more — builders just want to get moving fast
  • Prompt engineering can be productized with clear templates and logic
  • A simple tool, if well-targeted, can unlock creativity for a whole community

What's next for OnePrompt MVP Builder

  • Support for different output formats (e.g., Vercel, Replit, or other boilerplate generators)
  • Idea-to-prompt presets for popular use cases (AI agents, video tools, landing pages, etc.)
  • A gallery of example prompts submitted by users
  • One-click deploy with pre-integrated API environments
