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.

Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
