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.

Grok
- Up-to-the-minute answers on news and trends
- Strong reasoning models on paid plans
- Image and video generation in one app
- Closely tied to X and its data practices
- Looser content limits have caused public controversies
Grok, from xAI, stands out for real-time knowledge pulled from X, so it is quick on breaking news and trending topics. It also offers image and video generation, voice mode and a reasoning mode for harder questions. It is looser with content limits than most rivals, which some like and others don't. Privacy is the weak spot: it is closely tied to X, and its data practices have drawn scrutiny from EU regulators.
