LaPrompt

LaPrompt is a marketplace and gallery for buying and selling AI prompts, covering text, image, video, audio, and 3D generation. Buyers can search a catalog of prompts that have gone through a manual verification process, then get instant digital delivery along with an unlimited, royalty-free commercial license, so they can skip trial-and-error prompt writing for models like Midjourney, DALL·E, Stable Diffusion, Runway, Leonardo, KLING AI, and Sora. Prompts on the platform are generally priced in the roughly $3-$7 range. On the selling side, LaPrompt lets prompt engineers and creators open their own branded shop within the platform, set their own prices, and keep up to 80% of each sale; a single account can run multiple shops for different niches or model types. Sign-up is quick through Google, Twitter, or Microsoft accounts. The platform is aimed at two groups: designers, marketers, and content creators looking for ready-to-use prompts, and prompt specialists who want to monetize prompt libraries they've already built. Because the value of any individual prompt depends heavily on the underlying AI model's current version, older prompts can lose effectiveness as models like Midjourney or Sora are updated — a limitation inherent to any prompt marketplace rather than specific to LaPrompt.
