In the landscape of increasingly sophisticated AI assistants, KIMI AI is making surprising headway. Born in China and freely accessible from a browser, this chatbot created by Moonshot AI offers an extremely advanced experience, capable of competing with (and in some ways surpassing) much better-known tools such as ChatGPT, Claude or Gemini. Its most incredible feature? KIMI is able to manage long documents , read and analyze complex PDFs, understand uploaded or pasted text, and respond in a logical, clear and fluid way. All this even in the free version , without complicated logins and with a minimalist but functional interface.
