Editorial Verdict
AI-researched, not hands-on testedKimi is the AI assistant from Moonshot AI, now built around the K3 model for agentic coding and knowledge work, with Agent, Agent Swarm, Slides, Deep Research and Excel features. It suits developers and knowledge workers who want long-context, agent-style task execution. A limitation is that the plans and prices were not visible in static page content, so costs cannot be compared up front. For general assistants look at Gemini or DeepSeek, or self-host with LibreChat or AnythingLLM.
