Kimi
Kimi is Moonshot AI's assistant, known for long-context reading and increasingly strong agentic and coding abilities. The free chat at kimi.com is genuinely usable for research and testing, and paid membership (from ~$19/mo) unlocks the latest K2-series model, agent credits, Deep Research, and built-in tools for slides, websites, and code. Because the model weights are open-source, developers can also self-host or use a cheap token API with aggressive prompt-cache discounts. Like other Chinese labs, its appeal in the West is tempered by data-residency concerns and thinner English support.
You.com
You.com began as a web-grounded, citation-first AI search engine and has pivoted hard toward enterprise and agentic search APIs. As of April 2026 the old unlimited consumer free tier is effectively gone -- free users get a ~25-query Pro trial, with Pro at $20/mo and Max at $200/mo. The real strength now is the developer side: Search, Contents, and Research APIs with $100 in free credits, a free MCP endpoint (100 queries/day) for Claude Code and Cursor, SOC 2 certification, and no training on your data. It's a strong choice for building RAG and agents, less so as a casual consumer chatbot.
Kimi edges You.com on aggregate — 80 vs 78.
A serious open-weight, agent-focused contender with great API economics -- held back mainly by China-hosting trust and a thin Western footprint. You.com still wins for buyers who prioritise best-in-class web-grounded, cited answers (rag-ready). Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
