Microsoft Copilot
Microsoft Copilot is ChatGPT-class AI baked into Windows 11, Edge, and Microsoft 365, running on GPT-5-era OpenAI models in 'Smart mode.' The free tier is unusually complete -- voice, Think Deeper reasoning, Deep Research, image generation, memory, and web search. The standalone 'Copilot Pro' was discontinued; paid Copilot now comes bundled into Microsoft 365 plans (Personal $9.99, Family $12.99, Premium $19.99). Its superpower is native OS and Office integration; its weakness is brand confusion and no dedicated consumer API.
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.
Microsoft Copilot edges You.com on aggregate — 81 vs 78.
ChatGPT baked into Windows with a genuinely strong free tier -- but there's no standalone paid Copilot anymore, just Copilot bundled into Microsoft 365. 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.
