Used to train generative AI models0%
Your ratings, saves, and skips personalize what you see. Pooled together, they make our suggestions and catalog better for everyone, in a form that isn't tied to you. We never sell your data, and never use it to train generative AI.
Contains: statistical ML · text embeddings (similarity only) · image classification. All of it sorts and scores. None of it generates.
Free from: generative AI · chatbots · AI-written text · AI-generated book covers · cloud AI services.
How it's made: parts of the code were built with AI coding assistants, and our mascot Chappie and logo were drawn partly by hand (by our founder) and partly with AI image tools. People review and own everything before it ships. We build with AI. We don't put it between you and your books.
