Lexica
AI image search engine and generator with 30M+ indexed Stable Diffusion images - search by prompt or visual similarity, then generate with Lexica Aperture.
Lexica is an AI image platform combining a search engine over 30M+ Stable Diffusion-generated images with its own text-to-image generation model called Lexica Aperture, optimized for photorealistic outputs. Users can search the image library by entering natural language prompts and see what prompts other creators used to produce similar results - making it invaluable for prompt engineering and AI art discovery. Visual similarity search allows uploading a reference image to find stylistically similar AI-generated works. Lexica Aperture v4 produces high-quality photorealistic images that have compared favorably to Midjourney in community benchmarks. The platform offers 100 monthly fast generations on the free plan and unlimited generations on the Pro plan at $10/month.
