Microsoft Copilot, by contrast, is the stronger choice for summarising long email threads and Teams conversations instantly.

Its free tier also lets you validate the fit before paying.
Choose Microsoft Copilot if your priority is microsoft 365 enterprise teams on Word, Excel, Teams, and Outlook who want AI integrated directly into their existing tools without switching to a separate assistant, especially for drafting Word documents and PowerPoint presentations from meeting notes.

Learning curve is worth weighing. DeepSeek V4 has a known trade-off — Data privacy concerns due to its origin from a Chinese company may deter some users. On Microsoft Copilot's side: Dependence on Microsoft Ecosystem — limits its utility for users not already invested in the Microsoft 365 suite of tools. Factor in the integrations you already rely on — that usually settles which one sticks after the trial.
Both tools offer a free plan, so you can trial each side by side before spending anything. DeepSeek V4 is priced Freemium and Microsoft Copilot Free / $20–$30/mo; map the tier you'd actually buy against your real usage before committing. The sticker price rarely tells the whole story — check seat counts and usage limits before you commit.
