Pros / Cons
  • It provides Style and tone consistency across all users and Customizable brand tones and terminology Real-time suggestions that help teams write more clearly and confidently
  • Grammarly has frustrated me in the past because the extension does not always work with online word processing tools (even MS word online), so I have to copy/paste into the Grammarly portal. Plus, all of the advanced features are paid -- the free version is quite limited and almost not worth using.

  • It is the best AI content tool that I've used when it comes to creating product review content. Though they rarely have sales, the sales they do have are a great deal, which makes the per-article cost lower.
  • Also I would like to have the possibility to have more editing options in the outline writer and be able to regenerate certain sections after the first output, aswell as the editing options of the text right after generating it. When generating text in german second person, he mixes up formal and informal which is extremely annoying even when trying to enforce informal by additional prompts.
