Inspiration

I thought of this extension when I was trying to write prompts but didn’t get the results I wanted from AI. I wondered why AI itself couldn’t enhance my prompts. When the Chrome & Gemini Hackathon 2025 came around, I built Nano Prompt, which helps me and others improve AI prompts.

What it does

Nano Prompt helps people get better results from AI tools like Gemini, ChatGPT, or Claude. With just one click, it improves the user’s input and generates more effective prompts for the AI.

How I built it

As a junior full-stack developer who likes building practical platforms, I joined the hackathon. Using my knowledge of Chrome, Google, and coding, I developed Nano Prompt. I didn’t know everything at first, but building it helped me improve.

Challenges I faced

Working with the manifest file was tricky, as it was only my second time handling it. Most other issues were normal coding challenges, which I solved as any developer would. Each problem taught me something new.

Accomplishments we’re proud of

I’m proud of the final product. Two friends tested it and gave positive feedback. Using something I built myself feels really satisfying.

What we learned

I learned how to make extensions, target elements not directly in my site, and understand other authors’ code. I also improved my JavaScript skills, learning about the event loop, async/await, user input handling, and working with Manifest V3.

What’s next for Nano Prompt

  1. Add history tracking to enhance future prompts.
  2. Build a backend with Go for speed and efficiency.
  3. Create a landing page.
  4. Develop an app (optional).
  5. Make it profitable by adding payment options and API upgrades.
