Prexi is a curated prompt library for AI image generation, maintained by a three-person collective in Lisbon. It offers over 3,400 prompts tested on models like Flux, Midjourney, SD3.5, Nano Banana, Seedance, and Veo. Users can browse for free, copy prompts in one click, remix them, and generate directly from the platform. The library is organized into collections and riffs, and prompts are manually tested on each model to ensure compatibility. A free tier includes unlimited browsing and one preview generation per day, while the Studio plan ($9/month) provides 100 preview generations daily, unlimited collections, remix capabilities, and early access to new models. Prexi is designed for AI artists, designers, and creatives who want reliable, model-specific prompts without searching forums.
