Hi Product Hunt! 👋
I'm Flor, graphic designer and developer from Buenos Aires.
I built JSON Prompt Engine because I was tired of writing
AI prompts from scratch every time — and getting inconsistent
results across different models.
New in v1.1: an AI chatbot where you describe your idea in
any language and it automatically fills all fields with the
optimized prompt for each model.
Would love your feedback — what models or features would
you like to see next? 🙏
