Blog / WordPress / 9 Best AI Rewriter Tools in 2023 (& How to Use Them Ethically)

Regularly publishing fresh, relevant, high-quality content on your website is critical for Search Engine Optimization (SEO). Unfortunately, creating large volumes of content consistently is challenging. Luckily, you can streamline the content creation process using the best AI rewriter tools. They can help you create SEO content to improve your website rankings. They are also great for repurposing content in other channels (turning blog posts into Twitter Threads, for instance).

In this post, we’ll take a closer look at AI rewriters and how they work. We’ll also provide you with a list of the best AI rewriters on the market and some tips on using them ethically.

What Is an AI Rewriter?

An AI rewriter tool uses Artificial Intelligence (AI) to understand the original text’s meaning (such as an article) and rewrite that text content based on specific prompts either from the user or built-in to the software. This can be done to help with originality, change tone, and make writing more clear and concise.

AI rewriters can create new versions of existing texts, and some can generate entirely new content from simple prompts. They can be valuable tools for SEO writers, businesses, students, and anyone needing to create fresh content efficiently. In fact, some of the best SEO tools use AI to help optimize your content.

Several AI rewriters are on the market, each with strengths and weaknesses. The right one for you will depend on your specific needs and requirements. Don’t worry; we’ll point out the standout features of each one we review below.

Some tools are better at preserving the original meaning of a text while changing the text just enough. Others excel at creating a more readable and grammatically correct copy. And many rewriters switch out words with relevant synonyms or paraphrase and rearrange sentences. At any rate, AI rewriters can help enhance and polish your content. For instance, if you’re having trouble articulating a specific idea or want to rephrase and rework the structure of your article, the tool can offer helpful suggestions.

It’s important to note that plagiarizing content is never a good idea. While AI rewriters can help with many areas of content creation, you shouldn’t entirely rely on them for writing posts. Instead, it’s best to look at them more as an aid for your writing and editing than a substitute. More on that later.

How to Ethically Use an AI Rewriter to Refresh Your Content

As mentioned, we don’t endorse plagiarism or taking low-quality content from an article spinner and simply copying and pasting it without proofing. However, there are ways to ethically use an AI rewriter to freshen and update your own written content.

For example, an AI rewriter can:

  • Improve the quality of your existing drafts by discovering new ways to articulate ideas and structure your content.
  • Update your old articles to boost your SEO with reworded, fresh content (best paired with new research).
  • Expand your content by adding relevant information that elaborates on your original statements and ideas.

The best practices for you will depend on a handful of factors, including the type of content you want to create and the AI tool you’re using. For this post, we’ll use Jasper.

Using Jasper to Create New Content

First, you must sign up for a paid plan or a free trial. Then, you can navigate to Templates from the dashboard to select the type of content you want to work on.

Let’s say you want to create a blog post on proper dog nutrition; we suggest working in small sections.

For instance, you can use the Paragraph Generator template in Jasper to create an introduction for your post:

The Paragraph Generator template in Jasper.

Under “What is your paragraph about?” fill in a brief description. This text will give the AI rewriter context. You can also add any keywords to incorporate and your preferred tone of voice.

When you’re done, click on Generate AI Content. By default, Jasper creates three outputs, which you can view in the window to the right:

An example of a generated paragraph using Jasper.

You can also create a document from scratch. Navigate to Documents, then select New > Start from scratch:

The option to create a new document in the Jasper AI rewriter.

As with the Paragraph Generator template, you can create a title, add a description, and select keywords:

The Jasper Document editor.

After giving the AI rewriter a paragraph or two, click the Compose button. It will automatically begin writing fresh content:

An AI-written post.

You can use this content as the basis for your article. However, we recommend editing and proofreading it for flow, tone, etc. It’s also essential to ensure that there isn’t any repetition, which can often happen with an AI tool.

If you highlight any of the text, you’ll find a string of icons along the top of the editor toolbar:

The editing tool options in Jasper.

In order of appearance, these features are Rephrase, Fix Grammar, and Explain it to a 5th grader. You can also enable Grammarly or purchase the Plagiarism Checker addon.

Using Jasper to Rewrite Old Content

You can also use Jasper or other AI rewriters to update and refresh old content. The easiest way to do that is with the Content Improver template:

The Jasper Content Improver template.

Copy and paste the original text in the Content field, select a tone of voice, and click the Generate All Content button. Your new versions will appear in the New Outputs window:

The content outputs of Jasper's content improver templates.

Then, you can use the icons along the top to Add to Favorites or Copy to Clipboard. These are just a few of the many different ways you can use AI rewriter tools.

Regardless of your chosen solution, we recommend getting to know the interface and various settings. Familiarizing yourself with the full suite of features and options will help you use the software to its full potential.

What’s the best AI Rewriter Tool?

Content is a significant part of online marketing. However, regularly churning out lengthy articles consistently can be challenging. Keeping your entire archive updated and fresh is even more so. Fortunately, you can use an AI rewriter tool to simplify, streamline, and enhance the process.

The hard part when considering an AI rewriter tool is whether or not you are using it ethically. Many websites do not; they steal content from someone else and plagiarise it using these tools. That content is not rewritten. It is stolen.

We highly recommend Jasper for your AI content rewriting needs. It also does an excellent job with new content creation, making it a flexible tool for you to have. For paraphrasing and summarizing already written content, it is hard to beat Quillbot. It’s simply one of the best. Its additional tools, like the citation generator and grammar checker, bring it over the top.
