OpenPromptLib is a curated AI prompt gallery for creators exploring image and video generation. Its library features more than 35,000 prompts, with examples for tools and models including Midjourney, DALL-E, Stable Diffusion, Sora, ChatGPT Image, Nano Banana, Grok Imagine, and Seedance. Visitors can browse public prompts for free, filter the collection by image, video, or model, and open individual entries to review their full text and source details. The gallery is designed to help users study prompt-writing approaches and adapt ideas for their own AI-generated visuals.

OpenPromptLib also offers an image generator, allowing users to create images from their own prompts or begin with examples from the library. The built-in generator currently supports selected models, including Qwen z-image, Nano Banana 2, Grok Imagine 2, and ChatGPT Image 2. Image generation requires an account and uses credits; free credits are offered to new users, with additional packs and subscriptions listed on the pricing page. Although the library includes video prompts, video generation is not part of the current release.
