Turns a rough idea into a separate optimised prompt for ChatGPT, Claude, Gemini and Midjourney. Free tier, no signup required.
PromptProGen takes one rough description and returns four prompts, each structured for a different model: ChatGPT, Claude, Gemini and Midjourney. A prompt tuned for one model reliably underperforms on another, and this removes the manual adaptation step. Free tier requires no account.
PromptProGen solves a specific problem: a prompt tuned for ChatGPT reliably underperforms on Claude, and neither works well on Midjourney, which reads comma-separated token strings rather than sentences.
Describe your task once. PromptProGen returns four prompts โ a ChatGPT version using instruction-style formatting, a Claude version with structured context and explicit reasoning cues, a Gemini version with grounding context, and a Midjourney version in token syntax with parameters.
Most alternatives optimise for a single model, or emit one generic prompt and leave the adaptation to you. Per-model output from a single input is the difference.
The free tier requires no account creation. The paid tier is $19/month. Built and maintained by a solo developer.

React EnginePromptProGen's answer
PromptProGen is the only prompt generator that optimizes for 8 AI platforms from a single input โ Claude, ChatGPT, Gemini, Midjourney, Perplexity, Cursor, AI Agents, and Universal. It's also the only tool in this category with a live XML/syntax preview showing exactly how your prompt will render before you send it, a 5-dimension quality score on every generation, and version history with word-level diff tracking โ normally an enterprise-only feature. Our 26 core templates are free, while most competitors paywall their template libraries immediately.
PromptProGen's answer
Content creators and marketers writing prompts for blog posts, ad copy, and social content. Developers using Cursor or Claude for code generation. Founders and consultants building pitch decks, proposals, and outreach sequences. Researchers using Perplexity for structured queries. Broadly โ anyone who uses AI tools regularly and wants consistently better output without learning prompt engineering as a separate skill.
PromptProGen's answer
Most prompt tools specialize narrowly โ PromptHero focuses on image generation prompts, AIPRM is ChatGPT-only, PromptBase is a marketplace for buying pre-made prompts. PromptProGen is built for people who move between multiple AI tools in their actual workflow and don't want to re-learn prompt structure for each one. You also get transparency most tools don't offer โ a real-time quality score and live preview, so you know what you're sending before you send it, not just a black-box output.
PromptProGen's answer
The idea came from a recurring frustration: knowing exactly what I wanted from an AI tool but rewriting the same prompt structure manually every time I switched between Claude, ChatGPT, and other platforms โ each with different conventions for what makes a prompt effective. PromptProGen automates that translation step: describe your task in plain English once, pick your target platform, and get a properly structured prompt instantly, with a live preview and quality score so you can trust the output before you use it.
