'''Grammarly''' is an American English-language writing assistant software tool. It started as a tool to review the spelling, grammar, and tone of a piece of writing and to identify possible instances of plagiarism. Since 2025 it has integrated extensive generative AI tools, including options to generate essays from scratch, to suggest and insert citations, to "humanize" the text to avoid it being flagged as AI-generated, and to predict grades based on user input on the instructor, course, and university.<ref>{{Cite web |title=Grammarly for Students {{!}} Grammarly |url=https://www.grammarly.com/students |archive-url=http://web.archive.org/web/20260308144113/https://www.grammarly.com/students |archive-date=2026-03-08 |access-date=2026-03-12 |website=www.grammarly.com |language=en-US}}</ref> It can also make stylistic and tonal recommendations. An "Expert review" feature, which attributed Grammarly's editing suggestions to subject-matter experts in various fields, was discontinued in March 2026 due to criticism and complaints.<ref name=":0">{{Cite news |last=Klee |first=Miles |title=Grammarly Is Facing a Class Action Lawsuit Over Its AI ‘Expert Review’ Feature |url=https://www.wired.com/story/grammarly-is-facing-a-class-action-lawsuit-over-its-ai-expert-review-feature/ |access-date=2026-03-12 |work=Wired |language=en-US |issn=1059-1028}}</ref><ref>{{Cite web |last=Nelson |first=Decrypt / Jason |date=2026-03-11 |title=Grammarly Disables AI 'Expert Review' After Backlash From Authors and Journalists |url=https://decrypt.co/360748/grammarly-disables-ai-expert-review-backlash-authors-journalists |access-date=2026-03-12 |website=Decrypt |language=en-US}}</ref>
