Strengths and weaknesses
Microsoft Copilot
- Strong models free to use
- Copilot Vision helps with what is on your screen
- Works inside Word, Excel and Outlook with Microsoft 365
- Feels cluttered next to more focused rivals
- Many features depend on a Microsoft account
Microsoft Copilot gives you strong models for free, with voice chat, image creation and Copilot Vision, which can look at your screen or camera and talk you through what it sees. It is built into Windows and Edge, and a Microsoft 365 subscription brings it into Word, Excel and Outlook. The catch is that it feels less focused than rivals and nudges you toward Microsoft accounts and services. A good fit for Windows users.

DeepSeek
- Strong reasoning and coding help at no cost
- Shows its reasoning process in DeepThink mode
- Open-weight models you can run yourself
- Data is stored on servers in China
- Basic app with no voice mode or image creation
DeepSeek offers capable reasoning and coding help completely free, and its models are released as open weights. DeepThink mode shows its reasoning step by step, and web search is built in. The app is basic, though, with no voice mode or image generation, and servers can be busy at peak times. Its privacy policy says data is stored in China, and several governments have restricted its use on official devices.
