Grammarly vs ChatGPT: Precision Editor vs Creative AI Writer
Grammarly and ChatGPT both help you write better — but in fundamentally different ways. Grammarly works inline with everything you type across your browser, email, and apps, catching grammar errors, tone issues, and style problems in real time. ChatGPT is a generative AI that can draft, rewrite, and transform text from scratch. Together they are powerful; compared directly, they serve different stages of the writing process.
