What Is Hypotenuse AI?

Hypotenuse AI is foremost an AI content writer. It is designed to understand your brand and write in your voice. For enterprise users, you can send your brand guidelines and past writing to Hypotenuse AI. They’ll train the AI specifically to write in your voice.

For general users, however, the AI provides good-quality first drafts that require minimal editing. The AI writes everything, including titles, outlines, and the content. It’ll even provide citations and suggest topics to cover based on the top-performing content for your keywords or topics.

Plus, the SEO checker analyzes your content for basic SEO best practices. It looks at things like titles, readability, keyword density, and six other professional SEO rules. It’ll also propose remedies and make adjustments if you want.

You can also create numerous content types, including product descriptions, emails, social media posts, and more. Hypotenuse AI provides additional useful AI features, including an image generator, an AI that can read, understand, and answer questions about your PDF, a built-in chatbot, and much more.

Pros & Cons of Hypotenuse AI


Easy to use

Hypotenuse is easy to use, even for those new to AI tools. The platform is intuitively designed, with all your tools conveniently located on the dashboard.

Built-in chat

The platform has a built-in chat feature called HypoChat. You can ask it any question, and it’ll answer near-instantly. It also provides up-to-date information, including citations.

Multiple AI tools

There are multiple AI tools for different types of content creation. Whether you want to create a blog post, optimize the post for SEO, or generate images for your content, you’ll find this and more.

Good quality output

Hypotenuse AI consistently puts out good quality content. This includes blog posts, outlines, images, social media posts, and more.


Limited text formatting options

Hypotenuse AI text editor isn’t quite at the level of Google Docs. You can’t change fonts or font size, italicize, underline your text, and so on.

Basic SEO

SEO-savvy users will miss the advanced features dedicated tools like Ahrefs offer. These include detailed competitor insights, backlink suggestions and reports, traffic analytics, and more.

You’ll land on the dashboard, where you can explore the Hypotenuse AI tools and create your first project.

hypotenuse ai dashboard

Let’s see what Hypotenuse AI has to offer!

Blog Article

Hypotenuse AI has an AI blog article writer feature that lets you write blog posts from scratch with AI.

Open “Blog Article” from your dashboard and enter your topic in the prompt box. The AI also lets you add keywords if you like. This feature is useful for users who want to create Search Engine Optimized (SEO) articles.

hypotenuse ai blog article tool

We asked the AI to create an 800-word blog post about time management tips for college students.

First, the AI-generated a few title ideas for us to pick from. However, most of these titles we think were too long and would be cut off on desktop and mobile.

hypotenuse ai title ideas

Next, the AI generated an outline based on the title we chose. It was a good outline that was consistently on-topic. The outline also covered solid time management techniques.

hypotenuse ai generated outline

A cool thing about the Blog Writer is you can turn on SEO mode and the AI will pull ideas from Google’s “people also ask” section. You can add these to your outline to ensure you’re covering topics people are searching for.

hypotenuse ai people also ask

The AI will even give you sources to use for further research or to cite in your article. This is a lot more help than you get with ChatGPT or similar AIs. You can tell this feature is specifically designed for content writers.

hypotenuse ai generated sources

For the article itself, Hypotenuse did a good job. It was conversational and read just like a human wrote it.

The article also expressed emotion, which you don’t always get with AI-generated content. For example, this article sympathized with the reader’s struggle of juggling classes, studying, and extracurriculars.

hypotenuse ai generated article

The AI also created a strong conclusion. It provided a nice recap of the entire article.

hypotenuse ai generated conclusion section

Overall, Hypotenuse has a strong AI blog writing tool. We only have minor complaints. We wanted an 800-word blog article, but the AI created a 2,659-word post. That means we’d have to go through the article and cut out a lot of the excess content, which means more editing time.

There were also a few formatting issues. In this example, the AI added random characters to the content.

hypotenuse ai formatting issues

The AI created a wonderful FAQ section, but it wasn’t formatted correctly. The headings were mixed up with the actual content.

hypotenuse ai article formatting issue

We’d have also liked more text formatting options in the Hypotenuse AI editor. You can only create lists and not much else. This means you’ll need to copy and paste your content into a document editor like Google Docs to change the font, underline, italicize, and so on.

All things considered, Blog Writer is a terrific tool for creating content from scratch. The AI can pull information like citations and “people also ask” content to help you strengthen your articles. In short, aside from a few minor hiccups, Hypotenuse AI generates good-quality first drafts that you can edit to make publish-ready.

SEO Helper

“SEO Helper” is Hypotenuse’s AI Search Engine Optimization (SEO) tool. It scores your content for SEO and suggests improvements to increase your score. The SEO Helper is available in the Editor.

It’s a useful feature for increasing the chances that the AI-generated content performs well in search engines. This is especially important if you don’t have a lot of technical experience or skill with SEO writing.

hypotenuse ai seo helper

You can ask it to highlight the SEO issues in your article. Simply toggle this option in the left menu.

hypotenuse ai seo issues

We especially liked the highlight feature because it directs your attention to the exact place where you need to optimize your content. Plus, clicking the highlighted section tells you what you need to improve.

Plus, you can also ask the AI to fix the issue for you.

hypotenuse ai fixing article issue

You can also click the “SEO Checklist” on the right to see an overview of all issues. Again, this is a neat feature for getting a quick look at everything you need to do to improve SEO.

hypotenuse ai seo checklist

Again, you can click on any of these issues and Hypotenuse AI will fix it for you. In this example, the AI suggested that we should create a LinkedIn or Instagram post so more people would see it and share it.

Here’s the LinkedIn post the AI-generated in just one click. It didn’t take more than a minute to create the post.

hypotenuse ai generated linkedin post

The generated LinkedIn post was concise but still provided useful tips. It was also conversational and read as if a human had written it.

Finally, you can click the “Competitor” option in the right menu to see your competitors. These are the articles that rank high on Google for your keyword or topic. You can review these posts to get inspiration for improving your content.

hypotenuse ai serp competitors

If you’re wondering how the SEO checker can do all this, Hypotenuse AI uses a professional set of SEO rules to compute your score. The tool scores your content based on multiple SEO criteria, including Titles, Readability, Keyword density, Coherence, and more.

hypotenuse ai seo rules

The SEO Helper isn’t as advanced as dedicated tools like Ahrefs and Semrush. For example, you can’t analyze your competitor’s articles to see where they got right. However, most beginners won’t need this level of analysis.

Overall, we loved the SEO tool that Hypotenuse provides to optimize the AI-generated content. Not all AI writing tools go to this length to ensure the generated content is optimized for search engines. The tool was also very easy to use and provided solid tips and recommendations to improve our content.

HypoDoc AI

The HypoDoc AI tool lets you upload PDFs, and it’ll read the documents for you. Then, ask the AI any question about the document and it should answer correctly.

Open “HypoDoc” from your dashboard and upload your PDF. For this test, we generated a fictitious operational procedures manualusing ChatGPT.

The idea was to feed HypoDoc with very specific information that it could only find in our document. Just to make sure the AI wouldn’t source answers elsewhere, such as online.

hypotenuse ai hypodoc ai tool

The AI immediately summarized our document without any prompting from us. The summary immediately indicated that the AI understood what our document was about. Plus, the AI even suggested a few questions to ask it.

hypotenuse ai generated document summary

We opted for our questions, first asking the HypoDoc the effective date for the Workplace Health and Safety chapter.

The answer is March 1, 2023, and the AI got it right. It was also quick, taking only a few seconds to answer.

hypodoc ai answer

We asked the AI ten other questions based on our document. HypoDoc provided the correct answer each time.

hypodoc ai answer examples

What’s more impressive is that HypoDoc didn’t take the easy way out and provide short, pointed answers. Instead, it provided detailed responses, providing terrific context to better understand the answer.

In this question, for example, the answer “regularly” would have been good enough. However, HypoDoc provided crucial details to answer the question conclusively.

hypodoc ai detailed answer

The best part is you can ask the AI chat anything and not just what is in your documents. In this example, the AI correctly answered Elon Musk’s birthdate.

asking hypodoc ai a question

Additionally, the AI chat provides up-to-date information, including sources. We asked it a trick question about who owns Twitter. The AI correctly identified the new owner, including the fact that the company was renamed X Corp.

hypodoc ai generated relevant information

So whether you need to find specific information in a document, or are looking for additional information to supplement your documents, HypoDoc has you covered.

Overall, we were impressed by how well HypoDoc understood our document. It’s certainly a useful feature if you need to quickly find information without manually going through numerous documents or pages. It’s especially useful if you regularly work with contracts, reports, and other extensive documents.


HypoArt is a text-to-image generator. It lets you create images from a text description. It’s a useful feature to have if you need to create unique images for your content.

Open “HypoArt” from the left menu and enter your prompt.

We asked the AI to generate an image of a lioness in the savanna. We used a very detailed prompt to see how well the AI understood instructions.

hypoart tool prompt example

The result was impressive. The AI created a beautiful photorealistic image almost exactly as described in the prompt.

hypoart generated lioness image

What we really liked, though, is that HypoArt can take you step by step creating your image. This option is perfect if you’re not comfortable writing detailed prompts, like in our above example.

Simply enter whatever you have in mind in the prompt box. HypoArt will take you through the rest of the process. For example, it’ll ask you to choose an image type.

hypoart prompt settings

You’ll also pick an aesthetic, mood and lighting, and artist or style. This option makes it much easier to bring your vision to life without including every single detail in the prompt box.

hypoart aesthetic options

We were also impressed by the variety of images you can create with this AI. There are tons of styles and combinations to pick from.

hypoart style options

For example, we created this image by combining 3d render + steampunk + dramatic backlighting. It’s a beautiful, unique, high-quality image created from just a text prompt.

hypoart generated image

We also created a pencil sketch-style image with HypoArt. We enjoyed the creative freedom to experiment with different styles, moods, and lighting.

hypoart pencil sketch style image

We enjoyed working with HypoArt mostly because of how easy it was to create high-quality images. The AI lets you choose different moods, lighting, and styles to get the aesthetic you’re looking for. Plus, the image quality was consistently great.


Hypotenuse AI has three pricing plans. There’s also a limited seven-day free trial to test the platform before you purchase a subscription.

Closing Notes on Hypotenuse AI

And, from the promotion side of things, the AI quickly creates social media posts to promote your content. Overall, Hypotenuse AI is easy to use and affordably priced, so there’s no reason not to try it.
