Grammarly is a great tool that would work well for writers, business professionals, students, and more. The app is incredibly useful in helping to improve writing and offers tons of tools like idea generation, outline drafting, using a specific voice to reach your audience and checking for plagiarism, to name a few.

In my experience, if you're using within the Microsoft office suite, it has the best integration. The usability is great and the user has to put little effort to get a task done. On the other hand, in my experience, coding within Visual Code is unreliable and the results are not consistent. You can't use with different programming languages and ask for complex tasks. Pitty because I think the VS integration is great.

Pros
  • Integration with existing tools - Grammarly works in practically all text areas across your browser, including email and things like Google Docs, etc.
  • Quality control - the meat of Grammarly is checking your text and writing in real-time, directly as you type. Most of the time, Grammarly provides very accurate recommendations and quality checks on your text.
  • Analytics and reporting - Grammarly sends regular updates via email about your usage statistics and other detailed info. This type of reporting can be very helpful in tracking your progress over time.

Cons
  • Somewhat expensive.
  • Grammarly itself does not guarantee 100% correctness.
  • Sometimes, it does not remove the marked error even when you have corrected it.
  • Its MS office version faces some issues with plagiarism detection. I have to go on the web version to use plagiarism detection.

  • Like all other AI systems, Copilot suffers from hallucinations. You have to be very careful with the output it generates. It could be completely wrong. It needs to be checked and rechecked to see if it is correct.
  • Copilot sometimes struggles to formulate accurate responses to complex queries. It will either provide an incomplete response or generate a response that would be completely wrong.
  • Right now, I am unable to customize Copilot for my specific needs. Hopefully, in future versions of the AI, this will be taken care of.

Either I'm as dumb as a bag of nails, or Grammarly has been an invaluable tool in our communication arsenal since we've been users since 2017. I don't recall which podcast we heard it on, but it may have been when Jordan Harbinger was on Art of Charm. I listen to about 8 podcasts a day, so it was probably on something I listened to, demo'd it, and then ponied up for a paid subscription.

Absolutely!!! I have a high regard for the product and will use it for years to come.

Usability
It was very easy. I have it applied to all of my browsers as an extension so that I know I have entirely accurate grammar in anything I write for my company. I appreciate having something that will always be applied to anything on my computer. I wish I didn't need to use the Grammarly keyboard on mobile; I want it to read my text boxes like my computer does.

It's integrated well across the Microsoft 365 suite of applications, without getting in the way, and providing useful tools. Some of the integrations need development, e.g. the Outlook add on is quite basic, and the excel and powerpoint ones can't do much yet. The implementation in Teams is really fantastic, significantly improving the experience of recording, transcription, and summarising meetings and action points.

Support Rating
I have not really used customer support. I used the FAQ page to see how to re-install Grammarly because it wasn't functioning properly in longer documents. It seems to be working better now, but it still does not always underline all of the issues in the actual text. Thus, it is sometimes difficult to know where the errors are located.

Implementation Rating
Perhaps if you have a team that is not overly computer savvy, which in that case, I'd challenge your hiring decision, there's not much involved. I'm sure there are YouTube videos that go in-depth about implementation but it's really quite simple.

Alternatives Considered
While DeepSeek (or similar tools) is effective for specific use cases like sentence rephrasing or creative localization, Grammarly offers a more comprehensive and versatile solution for businesses. Its advanced features, integrations, and focus on professionalism make it the preferred choice for organizations seeking to improve communication quality and consistency across teams.

We needed a tool where secure data was not submitted to servers to process as we have some health care related data to keep private. We also needed to be able to test this tool without committing first to see if it is a fit and Microsoft provided this easily to us.

  • Service desk employees resolve some tickets much faster thanks to Copilot support. This percentage, according to current knowledge, is between 20% and 30%.
  • For administrators, creating scripts and automations with Copilot support saves them a significant amount of time. This currently stands at between 20% and 40%.
  • If you don't give the copilot proper instructions, you'll also get answers that aren't valuable. You do need some knowledge or training to get the right answers from the copilot.
