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
Perplexity
- +Citation-grounded answers are verifiable, a real advantage over uncited chatbots
- +Model flexibility: not locked to one LLM, with a proprietary search-tuned Sonar family plus frontier models
- +Genuine breadth from quick answers to research, deliverables, and agentic browsing in one product
- -The agentic features are supervised, not autonomous, and hallucination risk persists despite citations
- -Tier proliferation with the best features gated behind paid or US-only access
