ChatGPT
- +Broadest, most capable consumer AI assistant: chat, voice, image, search, files, and code in one place
- +Generous free tier plus a clear ladder of paid plans (Go, Plus, Pro, Business, Enterprise)
- +Agentic surfaces (deep research, agent mode) layered on top for users who need multi-step work
- -Mostly an assistant: the base product responds when asked rather than acting autonomously
- -Best agentic and reasoning features are gated to higher-priced paid tiers
Microsoft Copilot
- +Deepest integration into tools people already live in, grounded in org data via Microsoft Graph
- +A genuine agent platform with open MCP and A2A interop and multi-model choice (OpenAI, Anthropic, in-house)
- +Enterprise-grade controls, with licensed-user agent usage zero-rated in M365 apps
- -Layered, confusing pricing: the $30 seat is an add-on on top of a base license, and agents bill in separate credits that were renamed in 2025
- -The flagship in-app experience is assistant/copilot, not autonomous, so agent marketing can overstate it
