PromptHero

PromptHero is a prompt search engine and image generation service for people working with generative models. Its public library collects prompts contributed by its community, each shown with the model used and the generation parameters, so a visitor can study how a given result was produced, copy the wording, or run the same prompt directly on the site. Coverage spans Midjourney, Stable Diffusion, FLUX, Ideogram, Sora, Seedance and Nano Banana among others. The audience is split between people learning prompt craft and people who simply want images without running a local model. Searching and browsing is open, while a paid account adds the generation side: private, unlisted outputs, access to the full model catalog, faster queue placement and a profile that can pin prompts, add social links and display a featured image. The higher tier loosens content restrictions and grants priority access to new creator tools as they ship. Pricing combines subscriptions with credit packs. The free tier is $0 per month and allows a limited number of daily generations at standard speed, with every creation public and personal use only. Starter is $16 per month billed yearly at $194 and includes 3,600 generation credits. Pro is $24 per month billed yearly at $296 and includes 7,200 credits. Credits can also be bought outright without a subscription, at $59 for 1,000 credits or $99 for 2,000, and the site states that purchased credits roll over and never expire. Generations made from standalone credits are public and run at standard speed under stricter moderation, which the vendor explains plainly in its pricing questions.
