Grammarly fixes what you wrote, where you write it. ChatGPT writes or rewrites when you ask. For work email, that difference decides it. More on the [writing and email hub](/ai-life/work-study/writing-email/).

## Grammarly

Works inside Gmail, Outlook and most text boxes. Pro includes 2,000 AI prompts a month. Catches tone and clarity problems as you type. Best when you write your own emails and want them cleaner. {{< aff grammarly "Try Grammarly" />}}

## ChatGPT

Better at drafting from a few bullet points, summarizing a long thread, or rewriting for a different audience. You copy and paste, unless your email client has AI built in.

## Which one

- You write a lot and want it polished in place: Grammarly.
- You want drafts and summaries: ChatGPT.
- Your email app already has AI: you may not need either. See [best AI email client](/ai-life/work-study/writing-email/best-ai-email-client/).

Either way, read before you send. AI gets names, dates and promises wrong. Students should also check [AI study tools](/ai-life/work-study/study-tools/best-ai-study-tools-college/) and their school's rules.
