Lexica
Lexica is an AI image search engine and generator built on Stable Diffusion, letting you search millions of community images or create your own with the Aperture model.
About
Lexica serves two purposes in one interface. The search side indexes a large library of images generated by the community along with the prompts used to make them, so you can find visual inspiration or study how others phrase their prompts. The generation side, called Aperture, uses a fine-tuned Stable Diffusion model that produces photorealistic results from text descriptions. The combination makes it useful for both discovery and creation. It appeals to designers, prompt engineers, and anyone looking for reference images or a capable generation tool without the complexity of configuring models locally. Lexica offers a free tier with limited monthly generations, and paid subscriptions provide higher monthly allowances.
