In productionAI toolingNext.js

Problem

Nate B. Jones is an AI expert who writes guides and prompts on how to better use AI tools and LLMs. The idea was to turn his expertise into a tool where users can simply give their prompt and have it improved—expanding the prompt like Nate would, based on his proven methods and guides.

What I built

  • Built the product UI and core expansion flow end-to-end (web + backend integration).
  • Added user accounts, tiered subscriptions (including team subscriptions), and lightweight analytics/telemetry.
  • Shipped to production and iterated based on real user feedback.

Challenges & decisions

  • Balancing prompt expansion quality with response time and API costs.
  • Designing an intuitive UI that guides users without overwhelming them.
  • Implementing tiered subscription system (including team subscriptions) and analytics without compromising user privacy.

Outcome

Successfully shipped to production with positive user feedback. The tool helps users create clearer, more effective prompts by applying Nate's proven methods, improving their overall experience with AI tools.
