6 Best AI-Driven Content Optimization Tools

Content optimization is one of the most important aspects of content marketing. If the content is not optimized for SEO and the audience, it does not perform well. In today’s competitive marketing landscape, all digital marketers have to invest time and effort into making their content pristine. To do that, many people utilize content optimization tools to save time and effort. In this article, we are going to check out six AI-driven content tools that can help out marketers and content writers. So, without further ado, let’s check them out.

1. Yoast SEO

Yoast SEO is a provider of different kinds of tools and plugins that can help out SEO experts and digital marketers. It offers two kinds of tools that help with content optimization. The real-time content analyzer and the Bertha.ai writing assistant.

The real-time content analyzer by Yoast is a great tool for optimizing content. It provides the user with a multitude of information. It provides users with feedback related to SEO as well as user-friendliness.

It does not help with creating the content itself, but you can use it to check if your content is good or not. It provides the user with information such as:

  • Readability score
  • Recommended number of words in your sentences
  • Recommended number of words in your paragraphs
  • Recommended number of passive voice usage
  • Keyword density
  • Recommended number of Outbound links
  • Recommended number of Images

It tells you whether your content meets the recommended requirements or not.  In the case of excessive passive voice usage, and wordy sentences, it actually points out the offending sentences in the text.

By acting on its recommendations, you can improve the optimization of your content. 

2. Bertha.ai

Bertha.ai is a WordPress plugin that helps writers to create great copies. It works on WordPress only (unlike the content analyzer that runs on the web). This means that it is only useful for people who have a WordPress website.

It can help you with different types of content. You can choose from different templates and models to optimize your content.

You can generate a title, a call-to-action, or even a subheading with its help. Furthermore, this plugin generates multiple results each different from the other. So, you can choose the best one from the options.


  • Content Analyzer is free to use
  • Content Analyzer does not require registration
  • Great suggestions provided by the tools
  • Ad-free experience


  • Bertha.ai is exclusive to WordPress
  • Bertha.ai is paywalled


The content analyzer is free, while Bertha.ai has the following pricing plans:



3. Check-Plagiarism.com

Check-plagiairsm.com is an online platform that provides numerous AI-driven content optimization tools. However, in the scope of this article, we are going to limit our discussion to its plagiarism checker only.

The plagiarism checker is AI-based, and it can check your content against millions of online sources. This tool is a sentence-based checker and it can even detect paraphrased plagiarism. So that makes it quite good for optimizing your content.

You may already know that Google and other search engines do not like plagiarized content. They penalize web pages that use plagiarized content by either reducing their page ranking or removing that page from their index.

Let’s check the effectiveness of this tool by running a portion of this article through it.

Now, let’s see what kind of result we get.

That looks about right. But some people might not believe this. So, let’s use some plagiarized content as well, and check if it detects it correctly or not. For that, we are going to use some plagiarized text from a blog.

This is the text in question.

And here are the results.

And look at that, it detects all the content as plagiarized. The best feature is that it also lists the source of the plagiarized content. This can be seen in the following screenshot:

You can see that it found two sources, one of which is the one we used the text from. So, clearly, this tool works. With the help of this tool, you can check your content and see if there is any sort of duplication in it. Then you can deal with the duplication as you see fit and make your content 100% unique.


  • Accurate results
  • User-friendly user interface
  • Affordable pricing plan
  • Downloadable plagiarism report
  • “Exclude Source” feature


  • Ads in the free version
  • Small word limit in the free version


These are the basic pricing plans available for this platform.

4. Rephrase.info

This is another platform that provides multiple content optimization tools. However, for this article, we will only focus on its paraphrasing tool.

The paraphrasing tool in question is freemium, meaning that it can be used for free, but some of its features are paywalled. Those features can be accessed by paying for the premium upgrade.

With this paraphrasing tool, you can optimize your content by removing repetition from it and making it more engaging. You can also make it sound more fluent.

So, let’s see how the paraphrasing tool works. For the demonstration, we are going to use the introduction of this article and run it through the paraphraser.

There are multiple modes for paraphrasing, but only two of them are available for free users. In the demonstration, we used the “Fluency mode” which is one of the free modes. We can see that a considerable number of words and phrases have been altered. The changed words show up in red color.

The output is easier to read because the original words have been changed with easier and more common words. The Fluency mode in particular is good at doing this. The paid modes such as Creative and Smart are even better. The Standard mode on the other hand is only good for changing words.


  • Good free features
  • Does not require registration for the free version
  • No requirement for giving your credit card information
  • Supports 10+ languages
  • Option to get a significant upgrade with the premium version

You can also use this tool to generate headings as can be seen in the following image:

You can check the headings out and use them if you like them. But the fact that it does provide you with some options is great. Of course, you can use this tool to check your content for plagiarism as well. You do not need to open another page to do so. All you need to do is open the plagiarism-checking option from the toolbar.

It will check your work right there and then give you a plagiarism report. The plagiarism report contains the following things:

  • The plagiarized text, in red ink
