Lexica

Lexica is a text-to-image generation platform built around diffusion models, combining its own image generator with a searchable public gallery of AI-generated art. Typing a prompt and choosing a model and aspect ratio produces four image variations at once, which users can save, share, or mark as favorites; a private-image option is available on paid tiers. The platform's own generation model, called Aperture, has gone through multiple versions, with Aperture v3.5 covering styles such as photorealism, vector art, anime, and abstract composition. Separate from generation, Lexica's gallery holds a large library of AI-generated images, reportedly over ten million, each searchable alongside the original prompt, seed, and model information that produced it. This lets people browse existing artwork for inspiration or reverse-engineer prompts that achieve a particular look, which is useful for anyone learning how to write effective prompts for diffusion-based image models generally, not only on Lexica itself. Free access covers browsing and searching the image library. Paid plans start at $10 per month for 1,000 fast generations, rising to $30 and $60 per month for higher generation limits and private images. The tool is aimed at artists, designers, and other creative professionals who want both a generator and a prompt-research resource in one place; company details and founding history are not published on the site.
