What is Kimi?

Kimi is Moonshot AI's consumer assistant — the friendly chat app and website, distinct from the individual model releases that share its name. It is best known for swallowing very long documents whole: contracts, research papers, books and big spreadsheets can be pasted or uploaded and then summarised, questioned and cross-referenced in a single conversation, in Chinese or English.

Around that long-context core, Kimi adds web browsing, an agent mode for multi-step tasks, presentation and document generation, and a coding environment. The base chat is free, with paid membership unlocking faster responses and priority capacity at busy times. Its ecosystem is strongest in China, so some integrations and content sources are less relevant for users elsewhere in the world.
