Sometimes you get stuck in a writers block. You just can't figure out how to say exactly what you're looking for. You could have the facts, content, and syntax laid out... but just need a little boost. This is especially true if English isn't your native language.

If you're anything like me, you might be spending a lot of time with ChatGPT and noticed while it is great at producing answers and summaries to things, it often sounds like a robotic jumbled mess.

I've tried to hire many many writers and all of them use the same "In today's fast paced digital era" or "Undoubtably" pasted messages to apply. While I'm not against AI writing (I actually encourage it for many scenarios), if it sounds like a robot wrote it, nobody wants to read it. At least on a personalized blog.

If I wanted ChatGPT results, I would've asked 😉

With all of this, AI rewriting tools offer a valuable solution to speed up the writing process. I've also began to discover tons of paraphrasing and rewriting tools that keep the original content just change the layout to make it easier to read. This is also great for non-native speakers of a language trying to perfect the intricacies of their own content.

AI paraphrase tools use sophisticated algorithms for sentence rephrasing and restructuring, letting you easily modify a piece of writing's syntax. After extensive testing of various available tools, we've curated a list of the most reliable AI paraphrasing tools currently available today:

Undetectable AI

This is one of the newest tools I've seen and I can't get enough of it. Since it's launch this March, Undetectable AI has been attracting attention from AI writing tools aficionados because of how great it gets around AI detectors. Not just your ordinary paraphrasing tool, this tool produces output that almost always passes AI detection. You have a few options to tweak your writing and you'll get a response in a matter of seconds.

Features

  • Paraphrases and humanizes text
  • 9-Purpose selection

Undetectable AI paraphrased ChatGPT content

Pricing

The basic plan offers 10,000 words for $10 a month. I've noticed it sometimes adds random grammar errors and weird syntactical mistakes which I'm hoping is just a temporary bug (the team has told me they are releasing an update very soon to fix any issues and make the content more powerful). I'd still recommend giving it a try, at least the free plan.

Undetectable AI Pros and Cons

ProsCons
Wide selection of readability
Offers various purposes for writing
Provides results quickly
Bypasses advanced AI detection tools
API Access
Maximum of 10,000 characters per input

Sometimes has grammar errors

I wrote an entire review on Undetectable if you want to learn more. It's a really unique product spawned with the release of ChatGPT.

Founded by Trung Phan quite recently last October, this powerful AI tool uses natural language processing and sophisticated algorithms to manipulate writing.

Rephrase.info

Not to be confused with Rephrase.ai, Rephrase.info is another freemium AI writing tool founded a couple of years ago.

Brainflow

Formerly known as LuciaAI, Brainflow was founded by Swiss software engineer, Joel Wohlhauser. This AI writing tool possesses various writing features and claims that it has been trained on 45 TB of text data (around 10 million books). That's actually insane. Try it out and see if you believe it

Key Features

  • Answers questions
  • Writes text (headlines, blog posts, emails, etc.)
  • Paraphrases, shortens, and summarizes text
  • Generates and converts code, fixes bugs
  • Performs basic math problems

How Does Brainflow AI Works?

To use Brainflow, you just have to sign-up at Brainflowai.com. It has a straightforward UI that kind of reminds me of ChatGPT. On the left sidebar are the menu tabs: Writing, Learning, Marketing, and Coding. All the features are in clickable blocks, and the paraphrasing feature is on the Rephrase Text box. Pretty easy, isn’t it?

Pricing

The free version has a 2.5k-word limit per day. There is only one paid plan (Plus), which costs $10/month and has no word limit.

Brainflow AI Pros and Cons

ProsCons
Has a free version
Very user-friendly
Produces fast results
Drag and drop PDF files
Affordable price
No need to download software
Available in English and German
No Chrome Extension
Lacks important features (tone selection, history, etc.)
Inaccurate results (most of the time)
Some questions could not be answered
Lacks company information
Poor customer support

Which Paraphrasing Tool Should You Use?

While all of the above paraphrasing tools are legit, note that none of them deliver identical results. If reputation is your top priority, then Scribbr emerges as the clear winner (or QuillBot). However, Scribbr has limitations in terms of word count, making it less suitable if you’re looking for quick or free solutions.

Most of the other tools in the list have ample customization capabilities and can also generate exceptional results. You really just have to try them all until you figure out which suits your exact vibe the best.
