Grammarly

The polish layer you keep after the LLM drafts the mess

writing live

ChatGPT drafted the email; Grammarly stops you from sending the confident typo to the client.

Grammarly is cross-app polish—not your generative strategy brain.

Use it when writing spans Gmail/Docs/Slack, or when tone/clarity gates matter. Don’t use it as your only AI writer if you need strategy or research—pair it on top of Claude/ChatGPT.

Money: Premium vs “I already prompt carefully” is the fight; Business is for policy, not poetry.

Vs rivals: Claude/ChatGPT generate; Jasper runs campaigns; Grammarly catches you in the app you’re already in.

Pricing: Free · Premium · Business. Verify on grammarly.com — value collapses if you ignore suggestions anyway.
