PromptHero

PromptHero is a search engine and resource hub for AI prompts, focused on text-to-image and text-to-video generation. It aggregates millions of user-submitted prompts for models like Midjourney, Stable Diffusion, Sora, FLUX, ChatGPT Image, Grok Image, and many others. Users can browse, search, and discover hand-picked prompts from the community, as well as generate images directly through integrated AI models. The platform also includes an Academy for learning prompt engineering and a blog with tutorials and news. PromptHero is designed for creators, developers, and enthusiasts who want to streamline prompt discovery and generation. It offers a free tier with limited daily generations (public, standard speed) and paid plans that unlock private generations, higher credit allowances, faster speed, and priority queue. The platform supports both credit purchases for one-off use and subscription plans for regular creators. Key features include integrated image generation across multiple AI models, video generation support for models like Sora and Kling, community-driven prompt sharing, and specialized tools like AI wallpaper generator and AI album cover generator. The credit system is flexible, with purchases that never expire and roll over month to month. What sets PromptHero apart is its massive, searchable prompt library spanning dozens of AI models, its integrated generation capabilities, and its up-to-date coverage of emerging models like Nano Banana Pro, Seedream 4.5, and Kling 2.6. It competes with other prompt libraries but stands out for its breadth of model support and integrated generation, though it lacks dedicated API access or enterprise controls.
