Custom AI prompt builder — guided Q&A for any prompt
The Custom Prompt Builder asks you a short series of guided questions and returns a perfectly structured, ready-to-use prompt for Claude, ChatGPT, Gemini, Midjourney, DALL·E, Stable Diffusion or any other AI model.
It handles requests that don't fit the specialised tools: research briefs, marketing copy, analysis frameworks, story outlines, character sheets, image prompts, JSON schemas, evaluation rubrics — anything you can describe.
What you get
- Guided Q&A picks up on missing details automatically.
- Output is a single Markdown block optimised for your chosen AI model.
- Works for text, image, and reasoning-heavy prompts.
- Free tier available.
How it works
- Describe what you want. One sentence is enough — 'a research brief on Gen Z coffee habits'.
- Answer the follow-ups. Tone, audience, format, length, constraints — asked one at a time.
- Generate. Promptive writes the finished prompt in the format your target AI works best with.
- Copy and use. Paste into Claude, ChatGPT, Gemini, Midjourney, or wherever you need it.
