Frequently asked questions
Is Microsoft Copilot better than Mila?
For enterprise users on Microsoft 365, yes, Copilot integrates seamlessly with Word, Excel, PowerPoint, Teams, and Outlook. For users starting fresh who want AI-native architecture, Mila offers a more integrated AI experience without legacy software limitations. The choice depends on your existing ecosystem.
How much does Microsoft Copilot cost compared to Mila?
Microsoft Copilot: Free tier, Pro $20/mo, M365 Copilot $30/user/mo (requires M365 subscription). Mila: Free Hobby plan, usage-based Pro and Business pricing. Microsoft Copilot's enterprise tier is significantly more expensive but includes the full M365 suite.
Does Mila support Excel files?
Yes, Mila exports to .xlsx format. However, advanced Excel features (VBA macros, complex pivot tables) may not transfer perfectly. For basic to moderate spreadsheet work, Mila's export is functional. For Excel power users, Microsoft Copilot with native Excel is still necessary.
Can Mila replace Microsoft 365?
For documents, spreadsheets, and presentations, partially. Mila covers the core creation tools. It does not replace Outlook (email), Teams (communication), OneDrive (cloud storage), or the broader Microsoft enterprise ecosystem. For document-only workflows, Mila can work. For full enterprise productivity, Microsoft 365 remains necessary.
Which uses better AI models, Copilot or Mila?
Microsoft Copilot uses GPT-4 exclusively. Mila routes across Claude, Gemini, and GPT, automatically selecting the best model per task. This multi-model approach means Mila can use Claude for writing (often better) and GPT for other tasks. In practice, Mila's model routing provides more flexibility.
