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

Writer

  • +In-house Palmyra LLMs plus graph-based RAG and guardrails give enterprises strong control and compliance posture

  • +Deep enterprise integrations (Slack, Gmail, Drive, SharePoint, Gong) with event-based automation
  • -Enterprise-oriented; large deployments run into six-figure annual contracts
  • -Overkill for individuals or small teams that just need a writing assistant
