Microsoft Copilot

FreemiumAI chatconversational ai

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.

Freemium · Family $12.99/mo, Premium $19.99/mo. No direct consumer API (build via Azure OpenAI). As of June 2026.

EDITORIAL VERDICT · BIGBANGINDEX

Claude edges Microsoft Copilot on aggregate — 87 vs 81.

Wins on reasoning depth and long-context work where ChatGPT falls apart -- the go-to choice for developers and researchers who need accuracy over speed. Microsoft Copilot still wins for buyers who prioritise generous free tier (voice, think deeper, deep research all free). Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
