Which should you choose?

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

Copy.ai: AI platform for marketing copy and go-to-market workflows.

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.
