AI Prompt Generator

Turn a one-line idea into a prompt that actually works. PromptCraft AI is an AI prompt generator: type a few words, pick a category, and get a detailed, ready-to-use prompt you can paste straight into your favourite AI tool. Written for the tools you already use • Image — prompts for Midjourney, Stable Diffusion and DALL·E • Video — cinematic prompts for Runway, Sora and Pika • UI design, animation, games, stories, marketing copy and YouTube scripts How it works 1. Describe your idea in a line or two — or tap the mic and say it 2. Choose a category so the prompt is written the way that tool expects 3. Generate, then refine Refine until it's right Regenerate for a fresh take, Expand for more detail, or apply a style: More Detailed, Cinematic, Cartoon, Realistic, Minimal or Viral. Made it worse? Revert undoes the last change. Keep what works Star your favourites, sort prompts into collections, and search your whole history. Copy a prompt, share it, or export it as a .txt file. Start from a template Eight ready-made starting points — a cinematic opening, a character portrait, a finance dashboard, a game concept and more. Private by design No account, no sign-up, no profile. Your prompts are stored on your device. Generating sends only your idea text to the AI service — nothing that identifies you or your phone, because there is nothing to identify. Free, with ads.
