Prompt Builder
Freemium · $9/moTurns a rough idea into a structured prompt tuned for each AI model
What is Prompt Builder?
Prompt Builder rewrites a short request into a full prompt with a role, task and constraints, tailored to the model you plan to use, such as Claude, ChatGPT, Gemini or Grok. It is for people who use chat assistants for work and want better first answers.
You type something brief like a LinkedIn post about new pricing, choose the target model, and get back a prompt with sections laid out for that model. Tools include a prompt improver, prompt types, a saved prompt library and a hub comparing models in pairs.
A free Chrome extension brings it inside ChatGPT, Claude and Gemini so you can generate and refine prompts without switching tabs. Plans run on monthly credits, and the free tier gives five prompts without a card.
