AI book summaries plus a chat with any book
Generate a concise summary for any fiction or non-fiction title so you can grasp the main ideas without reading hundreds of pages.
Ask custom questions about a book's arguments, examples, or lessons and get answers grounded in its content, like conversing with the author.
Search by title or describe a topic and receive AI-driven reading recommendations across business, psychology, history, science, and more.
If a book isn't in the built-in library, add your own document and have the AI summarize and analyze it.
High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
