Mohamed W.

Jasper is incredibly efficient and intuitive. Most people use it to generate content like social media posts, tweets, and blog entries. I use it as a writing assistant to aid me in creating the content for my training materials and business consultations. It generates high-quality content rapidly when I need to write content that requires breaking down complicated phenomena into their subcomponents, explaining business processes, evaluating different options, or describing conventional management practices to the reader.


  • The given text suggestions are not always relevant or accurate.
  • The basic plan comes with a character limit of 800 characters for texts in editing.

  • You can’t buy credit without upgrading your plan.
  • Poor customer support.

Mateusz L.

Customer Support is Nonexistent. There is a chat, but no one replies to that – I have messages that are as “read” and unansweared. I’ve sent also few e-mails that were without answear too. I’ve tried joining their official group on facebook, but it seems no one manages that either and my invite is still pending. There is very large gap between the pro plan and the higher plan than that and that is a very big issue, as you can’t buy credits without upgrading your plan. There are features that are written on the website that are not in the product.

5. Rytr


per month

  • The tool is super friendly and easy to use.

Kelly M.

Rytr has been one of those apps that once I learned how to incorporate it into my daily operations, it became a tool that I can’t imagine working without. The ease with which you’re able to create your own type of assignments based on certain categories that are already predetermined, or where you could input your own, has to be some of the best artificial intelligence I’ve seen in this field so far.


  • Lacks in features and rolling of new updates.
  • The tool lacks good support and has limits on credits.


Having monthly limits on Credits is restrictive, but if you need more, you have to get a premium subscription Support is not upto the mark. I was on the Unlimited plan (USD 29) & canceled my subscription today. Many other AI writers are introducing more features and rolling updates much faster than rytr.

Vlad B.

Credits can expire if unused for too long, so keep track of them. Although this is a young company, it has much potential.

  • The tools misses on providing deeper subject matter knowledge in the content.
  • The tool lacks in replying to follow-up questions.

Jack R.

Lack of nuanced critique – The AI likely won’t provide deeper subjective evaluation or critiques that a seasoned human expert could. Important qualitative insights could be missing. Not customized – The standardized format may not be tailored to each user’s specific interests or priorities when reviewing a product. A customized approach may be more useful. Updates require rerunning – The AI would need to re-analyze to update summaries for new releases or features. It likely doesn’t dynamically update as a human reviewer would. Can’t answer follow-up questions – There is no ability to ask the AI clarifying questions or request additional details. The set summary is all users get.

Matt G.

Really easy WYSIWYG, drag and drop editor for landing pages, forms, etc. Also has integrations into things like Hubspot so our Marketing and CS teams can use them without the help of a web developer to quickly turn around content for webinars, etc.


  • Sometimes the software feels slow at loading.

Vaibhav S.

Sometimes, it’s too slow to load at Unbounce. Often, it’s hard to make a balance between mobile and web layout. Less options in free templates, but this is understandable as Unbounce has to make money too.

Marius A.

Hypotenuse AI is the best full-article AI writer I’ve ever used. Sure it still needs some human editing after, but the depth of the topic, the level of creativity and the quality of the final copy don’t have a match as far as I’m concerned. And I’ve used for at least 2 weeks each of the AI writers generally considered the best.


  • No free trial is available for individual users.


What I personally dislike about the product is, that Hypotenuse AI has no free tier for individual users and I can think of a couple of other apps that are freely accessible and can do similar stuff with a little bit of hassle for the user.

All you have to do is type a prompt in so the Ai generator can know the gist, but then you have to do nothing. This isn’t like one of those bogus online generators, G2 actually sounds professional and descriptive when they write. It is amazing. Also, if you run out of credits, there are ways for you to earn more credits without paying for them, it is amazing.


  • The tool generates only one version of the copy.

Verified User

That would be better if Anyword will suggest not only one version of topic but several. This way I would choose the best one that fits my requirements.
