Considered Both Products
Grammarly
Chose Grammarly
Grammarly is easy to use and I like its suggestions. Other AI tools are better for generating text, but Grammarly is better at optimizing it and catching grammar mistakes. I also like that it has the extension which makes it easy to use Grammarly anywhere without having to sign …
Chose Grammarly
The useability of Grammarly and the ability to get live feedback is much better than other programmes.

Other programmes prioritise AI to do the bulk of the writing. I like to do the bulk of the writing and let AI make suggestions; not the other way around.
Jasper
Chose Jasper.ai
It has an interface that makes it easy for anyone to use, regardless of skill level. They are ideal content writing tools for anyone looking to produce unique and engaging content.

I find I use Jasper.ai for social media posts, emails, blog copy and it works great. I have had to use it for longer form content which can be limited by the amount of words you can use or edit. I didn't have the best experience using it with generating images for my posts. It feels cumbersome and doesn't always get what I want

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.

  • Gives many outputs with little information given.
  • The outputs sound like a human wrote them, even though it's through a AI system.
  • There are many options within Jasper.ai that are useful within every aspect of our job.

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.

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.

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.

Overall it is easy to use...there are some areas where usability is a bit cumbersome especially when working between two different brands. The brand voices are different and you have to tell is over and over which brand you are working with at the time. Developing images has also taken away from it being a completely seamless experience

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.

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.

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.

It doesn't appear in your drop-down, but besides ChatGPT, I have also used Google Bard and You.com. All of them are AI that can create content. I have actually switched away from Jasper.ai to these other platforms because I can use them for free. Jasper.ai is definitely more robust in what it offers, but I am pretty good at creating prompts in the other free platforms, which has allowed me to get by with those.
