They can then view their library of prompts and edit them. The prompt editor should be a beautiful markdown editor. There should even be a button in the editor called “Optimize” that takes the prompt and sends it to the Claude Sonnet 4.5 API and optimizes the prompt to improve it. this should be a beautiful application using Tailwind/Shadcn. It should be NextJS and Supabase for database and auth. Get creative with the UI, don’t make it a basic AI interface.
