We’re now approaching 2025 and the problem of false positive AI detection still hasn’t been addressed. It was dangerous then, and it’s still dangerous now. Since AI detectors still can’t keep up with advancing LLMs, AI bypassers stepped in as an alternative way to avoid getting falsely accused of using AI.
I’ve tested lots of AI humanizers last year and I can tell you now that I can count on one hand which ones are even remotely worth their price. These are all of them:
TurnItHuman
As far as AI humanizers go, TurnItHuman is my latest obsession. I’ll be honest — I had low expectations of this one, but it quickly proved itself as one of the best AI bypassers today.
Apart from its accuracy, which we’ll talk more about in a bit, what separates TurnItHuman from the rest is its unique feature that lets you upload your own writing so the output doesn’t just sound like a human — it sounds more like you.
How Accurate Is TurnItHuman?
When I reviewed TurnItHuman, I tested it against the three best AI detectors I know: Sapling, Winston, and GPTZero. Here’s how it did:
- Sapling: 20.08%
- Winston: 43%
- GPTZero: 24.2%
I also tested it against my most used AI humanizer (Undetectable AI) and TurnItHuman blew it out of the water. Using the same input, Undetectable AI managed to avoid AI detection with an average likelihood score of 16.28%. TurnItHuman had 0.05%. So, yep, it’s pretty accurate.

Undetectable AI
If you’re a regular visitor of our website, you’ve already heard about Undetectable AI — and for good reason. Undetectable AI is the AI bypassing tool that I trust the most. It can remove common characteristics that AI detection tools usually flag, letting you disguise AI text (or something similar) as human-written.
How Accurate Is Undetectable AI?
We’ve done lots of Undetectable AI content over the past year, so there’s a bunch I could cite here as proof of how accurate Undetectable AI is. You can read our complete review or a random comparison article, and you’ll reach the same conclusion: Undetectable AI is a reliable AI humanizer.
But if you’re looking for something more in-depth, I recommend reading our testing of Undetectable AI against the eight most popular AI detectors today. Spoiler alert: it was able to avoid detection 19 out of 24 times (79.17% accuracy rate).

Phrasly
Like the first two, Phrasly is an AI paraphrasing tool that creates a “humanized” version of your input so that it could hide from AI detection. The difference is that it doesn’t have any output customization features apart from tweaking its “aggressiveness” — similar to Undetectable AI where you can switch between more readable, more human, or balanced.
How Accurate Is Phrasly?
I tested Phrasly against Undetectable AI earlier this year, and while it ultimately lost, it still put up a good fight with an accuracy rate of 60%.
How Much Does It Cost?
Phrasly has a free tier that lets you humanize 550 words with a maximum of three requests. If you want something more like 2,500 words per request, unlimited requests, and their pro engine — you could get their unlimited plan for an annual payment of $155.88 or monthly payment of $16.24.

CogniBypass
CogniBypass is an AI humanizer that you should also be using in 2025. CogniBypass can remove characteristics that AI detectors typically look for, like common words, repetitive phrasing, and more. It has two models: Nebula for more readable text (but less likely to avoid AI) and Meteor for quicker turnaround times.
How Accurate Is CogniBypass?
CogniBypass is one of the most accurate AI humanizers today. You can read more about it in this article, but the gist of it is that it avoided AI detection with an average likelihood score of 33.47%.

Humbot
And as for our last AI bypass tool — we have Humbot. This platform analyzes your input and then replaces words and phrases with alternatives that are less commonly used by popular AI language models and chatbots like ChatGPT and Claude.
How Accurate Is Humbot?
Humbot is reasonably accurate. When I tested it last year, it had an average AI likelihood score of 46.41% against Sapling.
How Much Does It Cost?

$119.88 ($9.99 per month) |
$359.88 ($29.99 per month) |

Okay so, reasonable prices, right? But here’s the thing: I hate hidden fees. Fortunately, most AI humanizers don’t have one — except Humbot. They locked their best model behind a paywall that you need to get for an extra of $3.99 per month to use.

So, Which Should You Get?
These are all great platforms. However, in my opinion, there’s only two that are worth your money, and here’s why.
Undetectable AI is a great get for anyone who’s looking for something established with a good reputation. Sure, it still has readability issues, but let’s be honest, which AI humanizer doesn’t? Fact of the matter is, I’ve tested it many, many times and it has never let me down, and that counts for something.
If you’re looking for the next big AI bypasser, then TurnItHuman should be your purchase. It’s the only AI humanizer I’ve used that managed to surpass Undetectable AI at times. The only thing that’s stopping me from crowning it as the best AI humanizer is its lack of mileage, but given how good it is, I’m sure it will get there soon enough.
So, that’s it for this article. Any of these catch your eye? If not, then I suggest heading over to this article for more information about bypassing AI detention. Good luck!
