Which should you choose?

Claude: Anthropic's AI assistant, strong at long-context reading, writing and analysis.

Grammarly: AI writing assistant for grammar, clarity, tone and generative rewrites across apps.

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.
