Which should you choose?

ChatGPT: OpenAI's AI assistant for drafting, summarising, data analysis and image generation.

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.
