Several sites have popped up all over the internet that promise to humanize AI-generated text. One of the new players in the game is TwainGPT. But before you rush over to give them your hard-earned cash, you have to ask, “Is TwainGPT legit?” We figured we’d help answer that question by doing a comprehensive TwainGPT review.

Everyone is looking for a way to make their workload lighter, from content marketers and bloggers to overworked and stressed students like you. And those students, bloggers and marketers have turned to generative AI to help lighten the load. And we totally get that. Since ChatGPT was released at the end of 2022, universities all over the world have started using AI detection systems to suss out AI-generated content.

TL;DR: TwainGPT promises to humanize AI-generated writing and help users bypass detection tools, but the reality doesn’t live up to the hype. While it claims to offer high-quality content for bloggers, writers, and those creating posts for social media platforms, the results are often disappointing. The output feels robotic and unnatural, frequently failing plagiarism checks and getting flagged by detection tools. Grubby AI, however, provides reliable resultswith natural, human-like flow and seamless integration across mobile devices.

TwainGPT: Readable Content or Low Quality Output?

Look, we get it. Sometimes, you just need some support to get through the mountain of work you have to do and the pages and pages of content you have to write. And AI-generated text seems like the perfect solution to your problems.

But a quick poke around on search engines or a look at the many social media posts out there shows that colleges and schools are all using the latest AI detectors to find and punish students for using AI-generated content.

There are also so many AI humanizers out there that promise to take that essay you used ChatGPT for and humanize AI-generated text that will bypass any detection tools out there. And sure, that can happen, but you’re not going to get high-quality writing or engaging content from most of them. But Twain GPT promises exactly that. So, I thought we thought we’d go try them out for ourselves and see what they had to offer.

To start this TwainGPT review, we headed over to that old friend, ChatGPT, to get it to write us a short essay on Hamlet.

TwainGPT Review: How it Optimizes AI Writing

ChatGPT's engaging output.

Then, we headed over to Turnitin, GPTZero, and Copyleaks to see if they picked up any AI-generated text. Unsurprisingly, all three detected something AI generated, with varying degrees of success:

Turnitin found 60% AI writing.

GPTZero showed us 100% AI content.

CopyLeaks also found all the AI-generated work.

With these results, it was time to put the TwainGPT bypass tool to the test.

TwainGPT Review: Does It Really Humanize AI-generated Text?

To test the TwainGPT bypass tool, we clicked on “Get started for free." We kinda expected what was coming next, and it was nice to have our suspicions validated. As soon as we clicked on the button, we were asked to login with our Google account. There are no other options for logging in.

TwainGPT asks users to sign in with Google, no other options at all.

Now, we don’t know about you, but we don’t like the sound of this. If you don’t mind knowing that you’re going to get a ton of spam by submitting your data, then you do you. We don’t think it’s worth it just to humanize AI. Luckily, we had a throwaway set up just in case, so we were glad to log in and get started.

The TwainGPT dashboard is pretty standard.

Here’s where we hit our second snag. Remember how we asked Chat to give us 750 words of content? Well, with Twain GPT’s free features, you can only humanize 250 words before you have to pay for more credits.

The free humanizing tool only lets you optimize 250 words of writing.

Nevertheless, we decided to use those 250 words to check the content quality, sentence structures, writing levels, and how natural the writing sounds. We also wanted to see the output’s originality and how human it sounded.

Analyzing the Content Quality: How Human is the AI Humanizer?

Right off the bat, something looked just a little off in the text we got back.

The writing this tool creates feels a little like spam.

TwainGPT's AI humanizer output didn't seem like high-quality writing. Since making AI seem more human is one of TwainGPT's key features, using phrases like "wide-ranging soliloquies" and "important depth" doesn't come across as readable content that writers would naturally use.

Overall, this didn’t improve content quality or make it seem less like AI and more human. But, to give TwainGPT the benefit of the doubt, we ran it through the AI detection tools again.

Testing the AI Detectors

To determine whether TwainGPT can humanize AI and bypass the detection tools, we put the output back into the essay and ran it through the AI detectors we used before. Once again, the AI detectors picked up the AI-generated text.

In fact, Turnitin picked up the "human" text that TwainGPT gave us when it had ignored sentences in that section before.

Turnitin's analytics picked up AI.

GPTZero and Copyleaks also hadn't changed their minds, with both still giving us really high AI scores:

Other AI detectors were also not happy with the writing levels.

To be fair, 250 words isn't a great test, but looking at TwainGPT's pricing made us realize it was not a cost-effective or comprehensive solution for bypassing AI detection.

TwainGPT Review: Pricing and Support

So, here's the thing: TwainGPT’s AI humanizer tool doesn’t exactly seem worth the price they're asking for.

TwainGPT users are limited by how much they can humanize.

From the pricing structure on TwainGPT's site, it looks like the company is pushing the AI detection features more than it wants users to make their content sound more human.

For $10 a month, you get 8,000 words but unlimited access to the AI detection tool. If you want more access to the content humanizer, you need to fork out $50 a month, but you can only input 2,000 words at a time.

Now, correct us if we're wrong, but doesn't that seem like TwainGPT's got some low quality features when it comes to helping its users create human sounding text?

TwainGPT Review: Final Thoughts

Maybe it's just us, but TwainGPT's tool seems to aimed at an audience made up of marketers, writers, and bloggers who will be using the features for content they plan on posting on social media platforms. And if social media posts are the content types users are creating and you're targeting, then why market your technology as a way to bypass AI detection?

What's worse is that while the AI-generated content didn't sound entirely human, the "humanized" content wasn't natural or engaging and lacked originality.

If you want to bypass AI detection systems, TwainGPT is just not optimized for that kind of technology. Certainly not at $50 a month for 2,000 words at a time.

Trust us, that's just not cost effective.

There are so many AI humanizers out there, so before you hand over your hard-earned cash, we recommend you look for the better, free tools available.

After thorough testing, it’s clear that TwainGPT struggles to deliver consistent, readable writing. Its support for users is limited, and the humanized content often sounds awkward and forced. Worse, it fails to pass basic plagiarism checks, making it hard to trust for serious work.

Grubby AI offers a better solution. Whether you’re a content creator, writer, or student, Grubby AI delivers polished, natural content that passes detection while maintaining authenticity. Plus, it’s optimized for mobile devices, ensuring you can create high-quality writing wherever you are. Why settle for mediocrity when Grubby AI has your back?
