The rise of ChatGPT & AI-generated writing is here! And sometimes you want to rewrite that. I've been using Undetectable AI for quite some time now & absolutely love it.
Undetectable is an incredible AI rewriting tool with extended features that allows you to rewrite any kind of AI writing to cloak it as undetectable across many AI detectors.
It produces fast results and is super easy to use. If you want to read exactly how it works, we have a complete Undetectable AI review where we go quite in depth.
As great as this tool is, there are a decent amount of alternatives that can make up where it doesn't do so well (or if you just want to try multiple tools!)
In conducting my own tests, I asked GPT-4 to write me a 500-word article about how to choose the best paraphrasing tools. Then I paraphrased it using six paraphrasing tools and checked the results using the Content at Scale's AI detection tool. Here are the results:
HideMyAI
HideMyAI is an AI paraphrasing tool that has similar features as Undetectable AI. Here, you can also use dropdown menus to select from seven different types of rewriting styles, eight educational levels, and four perspectives. HideMyAI also gives you a “detection likelihood” from popular AI detectors such as Originality and Content at Scale.
You can use HideMyAI for free, but only with 300 credits (which is equivalent to 300 words). If you need more, the tool offers a pay-as-you-go system starting at $10 with a 5,000-word limit. To save money, you can upgrade to the Pro plan that has a 10,000-word limit for only $8.25 a month. If any of your transformed writing gets detected as AI-detected content, you can get credits back for those generations.

Quillbot Paraphraser
Quillbot has been a very popular AI writing tool since its release in 2017. With its additional features including a grammar checker, summarizer, translator, and plagiarism checker, this tool is ideal for educators, essayists, and other writing professionals. No wonder, Quillbot has over 150 million users across the globe as of December 2022.
Quillbot’s paraphrasing tool has a free version with no signing-up required. However, it has a 125-word limit per input and only 2 writing modes. If you want it unlimited, go with the premium plan with a starting price of $19.95 a month. Once doing so, you can also enjoy all its features including the Paraphraser History and Plagiarism Checker.

Scribbr Paraphrasing Tool
Founded by two Dutch students in 2012, Scribbr was acquired by Course Hero not too long ago in September 2022. Even though they were acquired, Scribbr is still equipped with various writing tools, including a paid professional proofreading and plagiarism checker.
And like Quillbot, the Scribbr paraphrasing tool is free and has a125-word limit and 2 writing tones. The tool also produces colored text, depending on the variations. The main difference between the two is that Scribbr’s premium plans don’t include the paraphrasing feature. This means that you're always limited to 125 words per input.

Not to be confused with Rephrase.ai, Rephrase.info is a freemium AI paraphrasing tool also based in Pakistan.

Which Alternative Should You Use?
After conducting thorough tests, HideMyAI & Quillbot are the crystal clear winners as an alternative to Undetectable AI. HideMyAI does pretty much the same thing & QuillBot lets you customize & tweak words individually even further.
Scribbr’s paraphrasing tool is equally great in terms of quality. But unfortunately, it's not exactly practical when you're facing a mountain of content to rephrase.
For Paraphraser.io, I’d say the quality is above satisfactory, although the ads in the free version are really eye sore. But while the premium plans are very affordable, the tool has no refund policy. The number of languages it can paraphrase is impressive but I was not able to test them. Rephraser.info works the same but passed different detectors with a lower score. Plus, the ads in the free version are the worst I have ever encountered in a tool like this.
At the end of the day, picking an Undetectable AI alternative boils down to your specific needs. You could try a bunch of them and see what gives you the most accurate & consistent results. Remember, even the most sophisticated AI paraphrasing tool can't guarantee to fool all detection mechanisms all the time. There's an aspect of luck & unreliability to this. If you've used any of these & have comments, I would love to hear your thoughts in the comments below!
