Writers often ask: Is Grammarly AI detectable? The answer is no for editing, but yes for generation. Grammarly’s traditional role as a writing assistant—fixing grammar, punctuation, and clarity—does not trigger AI detectors. The text still carries a human style.

Grammarly Generative AI is different. It produces content from prompts, and AI detectors like Originality AI easily identify it as machine-written because of repetitive patterns and predictable flow.

Ways to avoid detection:
• Edit and rephrase AI-generated drafts with your own style.
• Use grammar and tone checks, but limit full content generation.
• Mix sentence structures and add personal analysis to increase authenticity.

Bottom line: Grammarly’s editing is undetectable, but its AI-generated content usually gets flagged unless carefully refined.
