GPTinf Reviews: How Good Is It at AI Text Humanization?

Like many creators, I'll admit it is incredibly tempting to use AI tools for all sorts of writing projects. But there is always that lingering worry: what if my content gets flagged?

GPTinf claims to be the solution, promising to render text completely undetectable so you can generate freely. However, rather than blindly trusting the marketing, I decided to contribute my own findings to the mix of GPTinf reviews. Can it truly fulfill its promise? Continue reading to find out!

In this article

Part 1. What Is GPTinf?

GPTinf is designed to rephrase AI-generated content to make it tougher for AI detectors to spot.

It works by mixing up the vocabulary, grammar, and sentence structures to avoid those AI patterns.

The goal? To create text content that evades even the most advanced AI detectors, free from the usual clues they're trained to catch.

Part 2. GPTinf AI Humanizer Pricing

I found GPTinf's pricing to be pretty flexible, which I appreciate. I can choose to pay monthly if I want to keep things simple, though it costs a bit more, or go for an annual plan to save some cash with a nice discount.

I started looking at their Lite plan, which is $9.99 a month—or just $4.99 a month if I pay yearly—for 5,000 words. If I need more, I can upgrade to the Pro plan at $24.99 a month for 25,000 words or even go all out with their highest plan for unlimited words.

Part 3. Testing GPTinf AI Humanizer in Real-Life

GPTinf claims a 99% bypass rate, so it has a lot to prove. I tested its real performance against some of the most popular AI detection tools.

First, I prompted ChatGPT to whip up a short article about the impact of AI development on massive industrial manufacturing.

Then, I ran the article through GPTinf to humanize it, hoping to make it evade AI detection.

Finally, I tested this humanized text with a bunch of AI detectors to check if GPTinf really delivers on its promise of creating undetectable AI content.

AI Detector Scale GPTZero Originality.ai Writer ZeroGPT
Result reads like AI 81% AI-generated, 6% human-written 100% sure content was generated by AI 93% certain content was AI-generated content generated by AI was 90.04%

1. GPTInf Against Content at Scale

Content at Scale marked almost all of the content red when I pasted the text from GPTinf to this AI content detector, and the result showed that the text "reads like AI."

2. GPTInf Against GPTZero

I took the output from GPTinf and ran it through GPTZero this time, but the results left me a bit disappointed. GPTZero flagged the content with an 81% probability of being AI-generated, giving it only a 6% chance of being human-written.

3. GPTInf Against Originality.ai

Originality.ai is known for being strict in AI content detection, and the result confirmed this reputation. It was 100% sure that the content was generated by AI, meaning that the content crafted by GPTinf had failed completely against Originality.ai.

4. GPTInf Against Writer

I then ran the content through the Writer AI detection platform. Writer AI was 93% certain the content was AI-generated, so it looks like I'd need to make some manual tweaks if I want the text to feel more human and bypass these AI detection tools.

5. GPTInf Against ZeroGPT

Lastly, I pasted the humanized content into ZeroGPT to see if I had any luck, but sadly it failed again. ZeroGPT marked all of the content yellow and stated that the probability of the content generated by AI was 90.04%.

Part 4. BypassGPT: A Top Alternative to GPTinf

If you are not satisfied with the results that GPTinf has to offer, or you are looking for additional and more advanced features in terms of AI text humanization, consider BypassGPT.

It's a solid alternative that packs in more humanization features, delivers better content quality, and performs reliably—all while keeping things affordable and user-friendly.

BypassGPT's state-of-the-art, AI-powered humanization technology is designed to bypass tough AI detectors like Originality.ai, GPTZero, ZeroGPT and much more.

Plus, it keeps the content's original meaning intact, so I don't have to stress about the humanized text changing the message or ideas I'm trying to convey.

BypassGPT is packed with a lot of features, way more than GPTinf offers right now.

I can choose from three bypass modes to fit exactly what I need. It is suitable for tackling contents like essays, professional reports, marketing material, etc.

BypassGPT's Real-World Performance

It seems like BypassGPT offers a lot of amazing features and clever tricks, but how does it really perform? Let's begin the test using the same AI article to see if BypassGPT is able to handle the pressure!

AI Detector Scale GPTZero Originality.ai Writer ZeroGPT
Result passes as human likely to be written by a real person 89% sure the content was originally written by a human 100% human generated content 20.2% likelihood of being AI-generated

Here is the humanized content generated by BypassGPT:

As you can see from the screenshot, there is a built-in AI detection section right under the output box, with a bunch of popular AI detection tools included. It's super convenient to check results without jumping to other websites, which is a big plus for anyone in a rush.

Still, I decided to test the output on each AI detection platform individually to ensure accuracy and thoroughness, and here is the result:

1. BypassGPT Against Content at Scale

The result from Content at Scale offered a good start. Getting a full green-marked and a human pass from this AI detector means that the content humanized by BypassGPT looked and read like human-written text.

2. BypassGPT Against GPTZero

The next one was GPTZero, and I was getting a pass as well. GPTZero considered the content was likely to be written by a real person, with a small amount of the text considered mixed or AI-generated.

Overall, BypassGPT was having no issue bypassing GPTZero's strict AI detection.

3. BypassGPT Against Originality.ai

Using its 3.0 model from Originality.ai, the majority of the text was marked in green, and the platform was 89% sure the content was originally written by a human.

Although there were some parts of the text that make Originality.ai considered AI-generated, BypassGPT still manages to get a pass from one of the most strict AI detectors on the market.

4. BypassGPT Against Writer

Then I put the humanized text into the Writer AI detector. It showed 100% human-generated conent.

Nevertheless, this result showed that the content humanized by BypassGPT could get a pass from Writer AI detection with no issues.

5. BypassGPT Against ZeroGPT

At last, I ran the humanized content into ZeroGPT, and the result was also pleasant.

Getting a “human written” rank with ease, none of the content was marked yellow by ZeroGPT, and a mere 20.2% likelihood of being AI-generated, a testament to BypassGPT's compelling AI text humanization capability.

Final Thoughts – Is It Worth the Investment?

In concluding my GPTinf reviews, I found the platform to be a straightforward and user-friendly AI humanizing tool. However, based on my tests, it might not be effective if I'm trying to bypass tough AI detectors like Originality.ai or GPTZero.

Luckily, there's a solid alternative such as BypassGPT for anyone like me who wants simple AI content conversion, top-notch content quality, and reliable bypassing performance.

Get your hands on it and you can experience its effectiveness for yourself!
