Pick PromptHero if you want a fast visual way to find proven prompts and styles for Midjourney, Stable Diffusion or DALL-E without rolling your own.

Skip if

Skip it if you need a programmatic generation API, fine-tuning, or a production image pipeline rather than browsing inspiration.

PromptHero is a community-driven search engine and gallery of generative AI prompts, indexing millions of prompts and reference images for Midjourney, Stable Diffusion, DALL-E, Sora and other leading image and video models. You browse by keyword, subject, artist style, lens or camera technique, see the exact prompt that produced each image, and remix it for your own runs. The site also bundles an in-browser image generator with monthly credits and a prompt-engineering course.

It is aimed at AI artists, designers and marketers who want to skip the trial-and-error of cold-starting a prompt and instead crib from work that already looks good. Pricing is freemium: a free tier lets you search and use limited generations, while the PRO plan (around $25/month billed annually) unlocks roughly 7,200 generation credits a month, faster queues and enhanced profile features. A marketplace lets prompt designers sell their work.

PromptHero is not a model trainer or a heavy production pipeline; it sits one layer above the model APIs as a discovery and learning surface. There is no public REST API for programmatic access, and the generator is more of a convenience than a replacement for a serious Midjourney or ComfyUI workflow.

Editor's take

PromptHero is the prompt equivalent of Pinterest for generative art, and it's genuinely useful as a jumping-off point. The PRO tier is fine if you also want generations bundled in, but most pros will keep using the native model UIs and treat PromptHero as a reference library.
