Comment summary: Grammarly receives praise for its effectiveness in grammar correction, particularly its free features. Users appreciate the clarity it offers in writing and the educational aspect of learning grammar usage. Criticisms include its premium pricing, alleged privacy issues, and resource consumption on devices. Some find the premium version underwhelming relative to its cost, and it occasionally causes technical glitches in applications like MS Office. Alternatives such as ProWritingAid are suggested for specific needs.

The tool not only helping me correct a lot of typos while I write but also help me learn English with proper grammar, with proper usage of "a/the", with "on/in/at" and many other things. It's also helping me sounds better. Also, I tried alternatives to Grammarly, and all of them much worst then Grammarly. If someone knows better alternative except ProWrittingAid - leave a comment below mine.

Cons:

  • price for premium - too high, really too high, I can't afford it.
  • Performance issues here and there
  • Do not work on many sites (1page sites like discord, youtube, etc).
  • Can really slow-down whole page loadings in different browsers (depends on the browser) on modern hardware.

If you have so many cons, why still 5 Stars?

Because there are no alternatives in the market at all which even close to Grammarly. And I do saying nothing about quality of corrections. I tried around 8-10 for sure. Grammarly best one in the market, far ahead of all other tools. But the price extremely expensive for such service.

If you criticize the app and give it 5 stars, the features you criticized will remain the same.

Grammarly is a proven keylogger. Its premiums are too expensive, and it's extremely English centered. There are several glitches as well, and it took forever to get Google Docs support, and it's not very good. Glitches include underlines in the wrong places when the text is long (it can't seem to keep track of any kind of deletion or the field moving), underlines for the wrong things (again, problems with deletion. Every single time it's a word that I deleted what feels like an hour ago), deleting entire blocks of text on some sites when correcting, duplicating entire blocks of text when correcting, duplicating the word without correcting, not correcting at all, moving my cursor, and not being able to handle various websites and circumstances that are common for long blocks of text. It hates google keep, Gmail, docs, school websites like canvas, and any social site that's not mainstream, and it REALLY hates when the message gets so long the text field gains a scroll bar.

It also just doesn't try on search bars regardless of if it's the browsers default field at the top of the screen, or on Google dot com in the middle of the actual website. One thing that also gets me is how it also doesn't know that "I'm" is a real word. Common spelling checker mistake that peeves me.

And then again, on top of all this, it steals your passwords and personal messages. Always use open source programs when you can. The way it asks for hundreds out of you for a spell checker disgusts me. Find a free one on here.

The most positive thing I can say is that it works well on Twitter and YouTube. Pretty much the only text fields where I don't find complications. So if you're the kind of miserable individual who only cycles between profitable social medias and that's your only internet experience, go for it… And stay far away from me!

After deleting the Chrome extension, I noticed that the CPU load decreased a lot. Although there are currently 20 extensions installed, they do not consume as much resources. I checked them all one by one. Also, the free version is not very useful. I can't buy the paid version because I don't use it all the time.

After one year of using Grammarly in a professional context, I decided I didn't like it.

As a non-native English speaker, it is practical for me to identify mistakes and correct typos on the go.

On the other hand, its excessive suggestions often change the meaning of the text, which IMHO is unacceptable. It has too many glitches, and I suspect it to slow down my old computer a lot. It often interferes with my mouse pointer when I edit text, which is highly annoying.

This review will be the last text edited with Grammarly on my computer before I uninstall it.

The free version is a great tool for basic grammar and spelling checks. However, it often freezes my MS Office apps and I find that disabling the app resolves the issue. Oftentimes, it gets a little bit intrusive with other things that I have to shut it off. Other than that, I hope it wasn't laggy with apps where I need it most. 🤷🏻‍♀️

With comprehensive feedback on spelling, grammar, punctuation, clarity, and writing style, Grammarly is more than just a proofreader. It’s a tool that helps you write with confidence, find the best words to express yourself, and communicate your ideas with ease. Grammarly’s generative AI capabilities allow you to produce instant drafts, ideas, replies, and more wherever you do your most important writing.

Grammarly analyzes your sentences as you write and adds color-coded underlines to words and phrases where you can improve your writing. You can apply Grammarly’s suggestion with a single click, or expand the suggestion to learn more about it.

Grammarly’s advanced spelling checker and grammar checker go far beyond the built-in tools of word processors. Grammarly can detect not only misspellings, but also commonly confused words used in the wrong context, like “affect” and “effect.” In addition, it can flag and fix complex grammar and punctuation issues like sentence fragments, comma splices, and subject-verb disagreement.

But great writing is about much more than just grammar and spelling. That’s why Grammarly also helps you streamline wordy phrases and rewrite sentences that are likely to confuse readers. It also suggests word choice improvements to help keep readers engaged, and helps you adjust your tone to ensure you come across the way you intend.
