Moonshot AI's long-context chatbot with a 2 million token window
What is Kimi?
Kimi is Moonshot AI's flagship chatbot, pioneering ultra-long context processing with a 2 million token context window — the largest of any consumer AI chatbot. Based in China, Kimi has built a strong user base among Chinese-speaking professionals and researchers who need to process extremely large documents in a single conversation.
The platform's defining capability is its ability to ingest and reason over massive documents — entire books, lengthy research papers, extensive codebases, and multi-hundred-page reports — without the chunking or summarization that other chatbots require. This makes Kimi exceptionally useful for document analysis, legal review, academic research, and any task requiring comprehensive understanding of large text bodies.
Kimi supports file uploads in multiple formats (PDF, Word, Excel, code files), web page analysis, and image understanding. The interface is clean and focused, with conversation management features that let users organize their research threads. Recent updates have added web search capabilities and improved multilingual support.
While Kimi's general-purpose capabilities are competitive with other Chinese AI assistants like Doubao and Wenxin, its long-context specialization is the key differentiator that attracts power users who need to work with large document collections.
