Comparison
ChatGPT vs Microsoft Copilot
ChatGPT and Microsoft Copilot both help with everyday business writing and analysis, but they fit into different workflows. Copilot leans on its place inside Microsoft 365; ChatGPT leans on being a standalone assistant with a broader third-party ecosystem. Here is how they compare.
OpenAI
ChatGPT
- Broadest ecosystem -- plugins, custom GPTs, and third-party integrations
- Voice mode and image generation built into the same app
- Not tied to any one productivity suite, so it works the same regardless of what tools your company uses
- Fast at producing high-volume, quick-turnaround output
Pulling in your own documents or emails usually means uploading or pasting them in manually, rather than acting on them where they already live.
Microsoft
Microsoft Copilot
- Built directly into Word, Excel, Outlook, and Teams
- Can act on files and emails where they already live, without exporting or copy-pasting
- Useful for teams already standardized on Microsoft 365
- Meeting features integrate directly with Teams recordings and transcripts
Most useful within the Microsoft 365 ecosystem -- teams on other tools may not see the same integration benefit.
