What changed for this shortlist

Impact score: 80

Estimated monthly cost: $176

updateApr 7, 2026

Microsoft 365 Copilot Business

Copilot is still strongest for Microsoft-standardized teams, but monthly pilots are no longer easy to mistake for the cheaper annual line. Buyers now need to model add-on versus bundle paths more explicitly before comparing Microsoft against ChatGPT, Gemini, or Notion AI.

updateApr 2, 2026

GitHub Copilot

Copilot is harder to dismiss as a cheap baseline-only choice now. For GitHub-heavy teams, the platform keeps its governance advantage while gaining a more credible extensibility story.

updateJan 27, 2026

Glean

This makes Glean more defensible as a governed enterprise context platform even for companies that do not want to standardize on one assistant, because it can feed Claude Code, Cursor, Copilot, ChatGPT, and other MCP hosts from one permission-aware layer.

Microsoft 365 Copilot Business

This lowers the near-term barrier for Microsoft 365 customers to standardize on Copilot Business, especially against separate AI seats, but teams still need to account for the required qualifying Microsoft 365 base plan underneath the Copilot layer.
