Chose Grammarly
It's been too long since I used Wordrake, which I think says a lot about how well Grammarly is doing in the marketplace.

We also saw the grammar checker in FlyMsg which is not as good as Grammarly.
Chose Grammarly
I found that ProWritingAid is harder to use than Grammarly and that some of its tips are too technical.

QuillBot was helpful for rewording sentences, but it didn’t check grammar as well as Grammarly does. It’s also not as strong when editing an entire document. In my opinion, …
Chose Grammarly
Grammarly makes it seamless to check your writing. Performance wise, they are about the same. But to use ChatGPT for checking writing, it required you to manually put the text in. It also doesn't allow you to automatically make the changes. It only makes suggestions which you …
Chose Grammarly
Built-in grammar checks and AI. They’re helpful in a pinch, but not for longer pieces or anything in excess of a sentence.
Chose Grammarly
The only program I know of that is similar is the onboard Apple spell-check, which will often miss several things that Grammarly does not. I also use Google Docs, which is not nearly as helpful as Grammarly since you can use it anywhere. Docs also misses things that Grammarly …
Chose Grammarly
Hemmingway. This is what I used before starting with Grammarly. The user interface might not be that great, but the best part is, it is free and even the premium version is way cheaper than Grammarly. You can also choose to turn off real-time suggestions and corrections. It can …
Chose Grammarly
I have not used anything like Grammarly before and that is probably why I love it so much. It works very well for what I need. Plus, it goes above and beyond. I don't need it all the time but it is great to use in any communication occasion. I love it
Chose Grammarly
[Google Drive] is good still I would say Grammarly is better, as it has real-time grammar substitution.
Chose Grammarly
I used to use the built-in Microsoft Word tools for spelling and grammar.

They DON'T stack up at all!
Chose Grammarly
Word also has some error detection, but it won't offer you a better or correct alternative.
Chose Grammarly
The only comparison that Grammarly has is the built-in spell checks used on the Microsoft and Google products suite. However, I find that Grammarly is more effective and offers more, such as the tone check, which is available for users on their free tier. There are even more …
Chose Grammarly
I have not used any other program like Grammarly. I didn't even know similar programs existed. I've used spellcheck within Microsoft office, but Grammarly I find is better at understanding context than Microsoft spell check is.
Chose Grammarly
Other than Grammarly, I have also used tools like Hemingway and ProWritingAid. But Grammalry has the best AI, which becomes obvious when you compare the suggestions each of these tools makes. Also, the style guide feature, support for multiple languages, and all kinds of …
Chose Grammarly
I do not know what program was used for spell check before I installed Grammarly, but the old program was nowhere near as thorough as Grammarly. Grammarly catches more errors, offers the correct word that is misspelled more often, is easier and faster to use. Offers grammar …
Chose Grammarly
Grammarly stands above the rest because:
1. It works with my MS Windows apps (MS Word, Outlook) and all my browsers (Chrome, Edge & Firefox).
2. It works with my IOS iPhone apps (MS Word, Outlook) and all my browsers (Safari, Chrome, Edge).

Microsoft 365 would be well suited for medium to large enterprises. This is where there are several hundreds or thousands of people. Since most everyone has used one of the applications the learning curve would be reduced. Another reason would be the ability to implement security measures to prevent access to sensitive data. This could justify the cost of an Enterprise license.

Pros
Grammarly
  • Ease of use - Grammarly is super easy to use. Anyone can use the app whether in a text editor like Microsoft Word or on the Grammarly website.
  • Integration - This one is a game-changer. It integrates with the main programs I use on a regular basis including email, Microsoft Office, Firefox, desktop, phone and iPads. I didn't need to change to anything or use something different so it was an ideal match.
  • Goals - This is a really cool function of Grammarly. With Goals, you can choose your audience, formality and domain type. So it works for a wide range of users. Depending on the audience type, Grammarly automatically can suggest changes to your content to help ensure your goals are being met.

  • Chat with teams and the integrations with the other apps, and many more smaller ones, like to-dos, news, and the recent Outlook integration.
  • Easy embedding on SharePoint to broadcast all the content created in the different tools.
  • The office package is still robust with the good things from the past and new additions.

Cons
Grammarly
  • User experience/technical issues on certain tools - in Google Calendar, for instance, Grammarly checks text that you type into the "Email Guests" modal window on calendar events. However, because of the way Google calendar works, if you right-click a word that Grammarly highlighted, the calendar event modal window will close and you will lose everything you typed. This is an extremely frustrating experience that has gotten me multiple times.
  • Incorrect suggestions - it doesn't happen that often, but occasionally Grammarly does highlight words or make suggestions that don't make sense or aren't optimal. I'm sure the Grammarly team is working continuously to improve the tool to make it smarter and smarter.
  • Lack of support on all platforms - although Grammarly works on most text areas you encounter online, there are still some areas it doesn't work - I'm not sure if this is an issue with Grammarly or not, but I haven't been able to figure it out.

  • Forms lack comprehensive features and parameters for detailed questioning for example cannot be directly linked with Power BI
  • Outlook email filters are not handy to use and require more detailing in terms of location past emails
  • Teams requires substantially large amounts of system resources which could be finetuned

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.

So far the Microsoft 365 platform provides features and tools that can cater to 100% of present organizations needs considering both technical and business necessities, however most features are not been effectively utilised at present. The current featureset is able to cover for most of the future needs of the business and technical functions.

Usability
Grammarly
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.

Microsoft 365 is the gold standard for performing project tasks in a professional environment, enabling the quick transfer and exchange of files and ideas for team members who work locally and remotely. Its suite of tools is familiar and has evolved to being cloud based, allowing for files to be updated in real time from near and far.

Performance
Grammarly
Again, here's another example of Maine being very happy with the product. The application quickly analyzes my writing and highlights areas for me to address. It doesn't correct everything without my support, and I like that because it gives me control over my writing style and tone and gets me close to being perfect in my grammar and syntax. I've never seen it have a problem with any application that I traditionally use

The Microsoft 365 tools expects and demands a substantial amount of system resources to operate at optimal level and even more when integrated with other applications which is a downside, however given that external supporting tech factors such as fibre/broadband speed bandwidth, high speed RAM and ample storage resources are allocated the tools work error free providing robust communication

Support Rating
Grammarly
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.

Over the past 8 years of using Microsoft 365, I have noticed that they change vendors often. This always leads to a poor experience in the beginning, then levels out after some time for the company to get things worked out. As a customer, it is really frustrating because I don't have time when something isn't working to have them "look into my issue" and get back with me. They have even closed a ticket I specifically told them to keep open. Your applications are only as good as the support.

The resellers involved with selling Microsoft products are reluctant to provide in person specialist trainings to consumers due to the fact of costs of economies of scale and is not provided free of charge most of the time.

The standard training offered with 3rd part resellers are fairly standard and covers the basic workability however the trainings needs to be specifically customised according to unique requirements of the organizations. for example an MSP would need to master specific communications verticals within Microsoft 365 whereas and online store using Microsoft 365 would needs to master a different set of tools within the suite to get the best ROI post implementation.

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.

The Microsoft support partners are more than capable of handling implementations and dealing with unprecedented errors during the implementations. Not part of the implementation though the setup was done with minimum misconfigurations which is evident with present live setup which works fine without any bugs and gaps at present context.

Alternatives Considered
Grammarly
Nothing comes close to Grammarly in terms of ease of use and quick setup. It practically works right out of the box without any rigorous configuration. It also allows you to pick a specific dialect which isn't available in other apps. And since Grammarly introduced AI features, its counterparts lost their advantage.

Typically I prefer working with companies with Microsoft 365 as their main tool because they're usually a fast growing company with a global presence. I like using it for work because it's easy to collaborate, share, review, comment, reply in any of the tools. The mobile app for Outlook and Teams are lifesavers when we're constantly traveling and you can join meetings on the mobile Teams to never miss a beat.

Grammarly has been an extremely reliable application for our organization. It works effectively across multiple applications, both traditional desktop and web. The more you see other web application bots floundering, Grammarly has never had that problem. When tools like LinkedIn make updates, Grammarly seamlessly works after the updates.

Have not directly obtained professional services from Microsoft but rather obtained specialized services such as implementations and configurations, setting up and integration support with Microsoft authorized suppliers, 3rd parties, and resellers, which has been a pleasant experience. Again the level of delivery quality on professional services is based on the level of hands on exposure of the 3rd party

Return on Investment

  • It saves me time.
  • It allows me to produce enormous quantities of writing to the highest quality with great speed.
  • Overall, it has greatly improved the quality of my writing .
  • Helps me get those pesky commas in the right place to improve readability.

  • We have a lot of nonprofit users, so they have a good ROI.
  • I like the constant updates without having to purchase the software repeatedly.
  • I used to purchase each Office (insert year here) often, so the software was up to date and had the newest options and connectors. I think my return on investment would have been much better if Microsoft had updated those versions to keep them current; after all, we did pay for them.
  • Microsoft 365's offering a monthly fee or a discount for a year helps, and you can look at it as a free backup if you have everything set to back up to One Drive. (Cloud-based document filing you can access anywhere ( with an internet connection)—you Can't beat that!)
