As we all know it Quillbot gets pretty easily detected by Turnitin. But what about Phrasly AI humanizer? Can it bypass Turnitin’s AI detection so that your writing looks absolutely human? The short answer is NO. Read on to know more details about it.
What does the dataset show?
We tested 100 rows of text. Each row contained:
- The original text,
- The paraphrased text produced by Phrasly AI humanizer,
- Turnitin’s AI score (from 0 = completely human, to 100 = definitely AI).
We also extracted some simple descriptive statistics:
- Count: 100
- Mean (Average) Score: 51.4
- Median Score: 49.5 (so half of the scores are below this and half above it)
- Minimum Score: 2 (very close to fully human)
- Maximum Score: 100 (very likely AI)
- 25th percentile: 25.5 (25% of scores are below 25.5)
- 75th percentile: 76 (75% of scores are below 76)

Distribution of Turnitin’s AI scores
The Histogram

If you plot a histogram of these 100 AI scores (0–100), you see:
- Scores spread all over the entire range.
- A small but noticeable cluster in the low range (0–20).
- A big bunch of scores between 20–80.
- Some in the high range (80–100) that are heavily flagged.
Because Phrasly AI is more of a marketing gimmick, although it claims to be an AI humanizer, it is one of those that doesn't work. You get everything from “looks quite human” to “definitely AI.”

The Boxplot

A boxplot for these 100 scores shows:
- The median around 49.5, meaning half the data is below 49.5 and half above.
- From 25.5 (25th percentile) to around 76 (75th percentile), which is a huge middle region (called the interquartile range, or IQR).
- Scores as low as 2 and as high as 100 at the extremes.
This big spread tells us that Turnitin isn’t certain that all Phrasly outputs are AI, but on average it sits around 50. That’s basically an “I’m not sure if it’s AI or not” kind of score. Still, you will occasionally see very low (2) or very high (100) detections.
Threshold view: Does Phrasly AI pass or fail?
Let’s look at how many of these 100 paraphrases land in certain ranges:
- Scores ≤20 (strongly human-like): 22 samples → 22%
- Scores ≤50 (low to moderate AI signal): 52 samples → 52%
- Scores >80 (very likely AI): 23 samples → 23%
So about 1 in 5 paraphrases (22%) appear quite human to Turnitin. That’s decent but not enough if you absolutely want to avoid detection. Around half (52%) get a score of 50 or below, which might be “uncertain.”
Meanwhile, nearly a quarter (23%) are flagged strongly as AI with scores over 80. If you rely on luck, you are basically risking that Turnitin might ring the alarm bell with a big “this is AI” label.
Is Phrasly AI Good for Turnitin?
The short answer is that it cannot be relied upon to bypass Turnitin always. Phrasly AI has marketed it very well. For instance, Similarweb suggests it has a traffic of 843,348, so it seems their marketing team is doing well but their core product just doesn't work.
One more thing is they fingerprint your device. So, if you try to create multiple accounts using temporary email addresses then they will reset your free word limit.
Which AI rewriter is built to do this job?
Some folks might mention specialized “AI humanizers,” such as DecEptioner or Stealthwriter.ai, that claim to produce text specifically to bypass AI detection. They keep training their models on data that helps them stay ahead of detectors like Turnitin. That said, even these tools are not 100% foolproof.
One single opinion to consider
If you’re thinking you can fool Turnitin entirely by using Phrasly AI, you should probably think again. It is too unpredictable. Our data says that only 22% of the time it scores as strongly human-like, whereas 23% is strongly flagged as AI, and the rest is in a mixed zone. So, from a purely pragmatic perspective, it’s a big gamble.
Moreover, trying to bypass AI detectors raises academic integrity concerns. You might also get flagged for plagiarism if it’s not purely your work. If you are a student worried about your academic results, then it’s better to focus on writing your paper in your own words or referencing your sources carefully.
Frequently Asked Questions
Q1. Does Turnitin detect Phrasly AI?
Yes, it usually will. You might get “lucky” occasionally and see low scores, but it is far from a guaranteed pass.
Q2. Is using Phrasly AI plagiarism?
Not if you feed it your own text. But the paraphrased text might still trigger Turnitin’s AI detection because it relies on patterns typical of AI writing.
Q3. Can Turnitin detect small paraphrasing changes?
Yes. Turnitin is known to be quite strict about detecting patterns that look AI-generated. Minor tweaks or synonyms often fail.
Q4. Is there a sure-shot method to beat Turnitin’s AI detection?
No, there is no flawless solution. You can either do manual rewriting with a unique style, or use specialized AI humanizers like Deceptioner, but even then you’re not guaranteed to escape detection.
The Bottom Line
If you are looking for a consistent pass, Phrasly AI humanizer is not your best friend. The scores range widely, from as low as 2 to as high as 100. About 22% of its outputs might look human-like, but around 23% are strongly flagged as AI. So, yes, it might sometimes give you a paraphrase that sneaks by Turnitin, but it often won’t. And that is a risk you probably don’t want to take—especially if you care about academic integrity.
