Turn Any Idea or Image Into a Perfect AI Prompt

Free AI prompt generator for every model

PromptMake is a free AI prompt generator and image-to-prompt tool built for creators who use Midjourney, FLUX, DALL-E, ChatGPT, Claude, Gemini, and Sora. Turn a rough idea or any photo into a polished, model-ready prompt in seconds — no sign-up required to start.

Whether you need a free prompt enhancer for text, a free image to prompt generator for reference photos, or a dedicated free Midjourney prompt generator tuned to your style, PromptMake handles both workflows in one place. The tool supports Text, Image, Video, and Audio categories — each with its own set of parameters — so you always get the right output structure for the right medium.

Dedicated landing pages at /for/[model] let you bookmark the exact tool for your workflow: free FLUX prompt generator, free ChatGPT prompt generator, free Sora prompt generator, and more. Each page is pre-configured for that model's preferred prompt format.

Why strong prompts change everything

Vague prompts produce generic, forgettable output. Specific, well-structured prompts activate the model's full capability — precise compositions, correct aspect ratios, accurate moods, and the exact style you're after. The difference between 'a portrait' and 'a close-up portrait of a woman, soft rim light from the left, shot on Kodak Portra 400, shallow depth of field, cinematic' is the difference between a placeholder and a deliverable.

For image models, a strong prompt includes subject, environment, lighting, lens or medium, color palette, and style reference. For language models like ChatGPT and Claude, the key ingredients are role, task, constraints, output format, and examples. Our free prompt optimizer bridges the gap between a rough creative idea and production-ready instructions — automatically, for every model.

Two workflows: idea to prompt & image to prompt

The Text tab handles idea-to-prompt generation and prompt enhancement. Type a short idea — even a single sentence — pick your target model, select a content type (Text, Image, Video, Audio), and hit Generate. The free prompt builder adds the structural elements your chosen model needs: role and format for ChatGPT, weighted descriptors for FLUX, camera movement for Sora.

The Image tab runs vision analysis on any uploaded photo (JPG, PNG, WEBP up to 10 MB). It analyzes composition, subjects, lighting, color palette, textures, and style — then translates what it sees into a text prompt calibrated for your chosen model. This reverse prompt generator workflow works across Midjourney, FLUX, DALL-E, Stable Diffusion, and Leonardo.

Supported AI models and platforms

PromptMake generates prompts for the most-used AI platforms: Midjourney (v5, v6, Niji), FLUX.1 (dev/schnell/pro), DALL-E 3, Stable Diffusion (SDXL, SD 1.5, Pony), Leonardo AI, ChatGPT (GPT-5.5, o1), Claude (3.5 Sonnet, 3 Haiku), Sora, Runway Gen-3, and Gemini. Each model tab is tuned to that platform's preferred prompt format — no guessing, no reformatting.
