Grammarly
Writing assistance that checks grammar, tone and clarity as you type


1/3Grammarly checks writing as it is typed, wherever the typing happens: a browser extension for Chrome, Safari, Firefox and Edge, desktop apps for Windows and macOS, keyboards for iOS and Android, and add-ins for Microsoft Word and Google Docs. Beyond spelling, grammar and punctuation it suggests full-sentence rewrites, flags tone, and offers generative features such as drafting, paraphrasing, translation and citation generation, each drawing on a monthly prompt allowance that differs by plan. Paid plans add plagiarism and AI detection, and a set of agents for narrower jobs like citations, resumes and predicted reader reactions. For organisations it adds style guides, brand tone controls, analytics and admin controls, along with an editor of its own in Grammarly Docs. It is sold as part of Superhuman, the wider productivity platform the company now markets, and is aimed at anyone whose work is judged on how it reads: students, marketers, support teams and professional writers.

Every answer links back to the mentions it came fromIs Grammarly considered an AI tool?
There is widespread agreement that Grammarly is an AI-powered tool, with many users noting that it has evolved from a simple grammar and spell checker into a generative AI platform. While some users distinguish between basic grammar suggestions and generative features like sentence rewriting, others argue that the entire service now functions as AI, leading some academic institutions to ban its use.

Does using Grammarly help improve my writing skills?
Opinions are divided. Some users report that their grammar has improved by reviewing the tool's suggestions to understand their mistakes. Conversely, many others argue that relying on the software prevents users from learning, as they become dependent on the tool to fix errors rather than internalizing the rules themselves. Some users even report continuing to misspell the same words after years of using the service.

Is it safe to use Grammarly for academic or professional work?
There are concerns regarding both privacy and academic integrity. Some users warn that Grammarly sends text to remote servers, posing a potential data security risk. In academic settings, students report that professors are increasingly banning the tool, and some claim that plagiarism or AI detectors can flag work that has been edited with Grammarly, even if the user wrote the content themselves.

What people are saying about Grammarly
52% negative“You used Grammarly for NLP (natural language processing) errors, I.e. to point out natural errors and draw attention to the mistake. There is a notable distinction in publishing/ editing regarding these 2 routes of AI usage.”
“Your book did absolutely use AI both in your research and with Grammarly. But I don’t think that’s what people meant.”
“Yeah so grammarly uses AI to do all of that. So basically you used AI to write the novel and are now baffled people are accusing you of using AI to write your novel. Lmao.”
“When using grammarly or other software, are you looking for synonym options for different words OR are you having the program rewrite the sentence or phrase for you?”
“I dunno if this is relevant, but I work as a freelance editor, and I've had clients "edit their book with grammarly" and when I get it I can tell -- because it reads like an AI wrote it. This is especially apparent if I've worked with the author before and I know their style”
“Both Microsoft Word and Grammarly have AI integrated into the software / websites. The second AI touches anything, it triggers a notification for AI-generation.”
“Grammarly is AI. And you use AI for research. Seems pretty clearly human/AI mixed to me.”
“Idk about grammarly, but I was using a similar program and the rearranged sentences never made any sense. Not even that it was a bad choice, most of the time it wasn’t even a complete sentence anymore!”
“Second, I am laughing because my little Grammarly G bubble is in this reply window, letting me know I have errors. Don't worry, I am ignoring them.”
“Texting oomf while using Grammarly at the same time. My texts got mixed up, and now I’m so embarrassed lol. I thought I’d need Twitter to compensate for the embarrassment”
“Same way grammarly or spellcheck works on word.”
“Grammarly is fine, just don't use the sentence rearrangement one tho. Like it tells you to write a sentence in a better way, don't use that one.”
“That is what is being flagged, there are almost always several grammatically correct ways to write something; Grammarly, like all AI, falls into detectable patterns when making those choices.”
“If someone to use Grammarly on the paid version where it smooths out the words (or however they call it) then it'll start to twig people with a keen eye for AI because, well, it's using AI models to rewrite.”
“I will say if you use the grammarly to rephrase anything it will trigger them even though you aren't actually using AI in this case. And it's honestly so annoying you can only really use grammarly to fix individual words or spelling mistakes.”
“I use Word and Grammarly for my writing and only use AI for research.”
“Don't pay for Grammarly, use LanguageTool”
“rememeber early grammarly when like it, in hindsight, was obvious they were using an early AI prototype and it sucked ass and if you used it you were an idiot”
“Copied that documentation to Grammarly and they said 0 AI detected.”
“I always laugh whenever I go to edit a @readwise quote to leave a note, and Grammarly absolutely obliterates the author's original language and sentence structure.”
“My grammar improved with Grammarly. If it flagged I would consider it.”
“Basically wiring it to function like grammarly.”
“Ask if your department has Read&Write. It’s not the same as Grammarly but it has some similar features.”
“I had grammarly before the LLMs being the thing they are now. Professors are just resisting something they cannot for no reason giving a generation headache.”
“i would not trust Grammarly humanizer and detector even a bit because it already has the reputation of not being a good tool.”
