Which should you choose?

Microsoft Copilot: Microsoft's AI assistant, available on the web, Windows and inside Microsoft 365 apps on eligible plans.

DeepSeek: AI assistant and models known for strong reasoning and low-cost API access.

The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
