BrandWell AI Detector Review: Is It Accurate?

Nearly three out of every four new web pages contain AI-generated content, according to an Ahrefs study of 900,000 pages published in April 2025. Only 25.8% of the pages were found to be entirely written by humans.

So AI writing has become the default in the industry, and this surge is exactly why AI detectors have become more important than ever.

BrandWell's AI content detector is one of the tools made to address this trend.

But how good is it at separating genuine human work from machine-written text? That’s what I wanted to know. So I tested the AI detector myself, and the results were not satisfactory.

This BrandWell AI content detector review will tell you about my experience using the tool and my findings after testing the detector on both AI- and human-written samples.

Let's start with a brief overview of the BrandWell AI detector.

What is BrandWell AI Content Detector?

BrandWell AI content detector is a basic AI detector tool offered by BrandWell alongside its core content marketing tools. The AI detector is fully free to use and simply tells you whether the given text is human or AI without giving a score.

You can scan 2500 characters at a time. When you try pasting more words, you’re prompted to upgrade to a paid plan.

There’s something strange about BrandWell’s website. You won’t find a way to navigate to the AI content detector, plagiarism checker, AI image detector, etc, from within the website. You can only access them through Google search results.

Moreover, when you choose to sign up to BrandWell, the website asks for a company email, which shows that their AI detector isn’t a tool for individual users.

Before being BrandWell, the platform was called Content at Scale. It was launched in September 2022 as the world’s first long-form AI content writer.

BrandWell AI Detector, formerly Content at Scale, also claims to have launched the first AI detector in October 2022.

The change from Content at Scale to BrandWell happened in 2024 when the platform transformed into a go-to-market (GTM) system.

How I Tested the BrandWell AI Detector

To test the effectiveness of the BrandWell AI detector, I used the same methodology that has proven successful in reviewing other AI detectors in the past. For example, read the ZeroGPT AI Content Detector Review, where I used the same method.

The methodology involves testing an AI detector against both fully AI-written samples and fully human samples.

Here’s some more detail about the two sets of samples:

• AI-written samples: These are 6 samples in total generated with Claude, ChatGPT, and Gemini. I gave two different prompts to generate two samples with each of the above-mentioned AI models.

• Human samples: Human samples were 8 in total and diverse in nature. To make sure they are truly human-written, I hunted down text written and published before the dawn of generative AI. The most recent sample was from 2019, and the oldest was from 1851.

They included news articles, an academic paper, novel text, a Wikipedia article, historic news, and a video transcript.

Let’s find out how BrandWell rated these samples. Spoiler: It was not satisfactory.

Is BrandWell AI Detector Accurate?

As I mentioned earlier, BrandWell AI content detector doesn’t show an AI or human probability score. It simply says whether the text reads like AI or passes as human. 

When it can’t put its finger on any of the two options, it leaves you hanging with a verdict that only says “Hard to tell.”

In all three situations, BrandWell highlights the sentences in your text in a range of five colors, each showing how close that sentence leans toward human or robotic.

These are the five colors: 

• Green: The highlighted content is human-written.
• Yellow: The highlighted content needs to be more human-sounding.
• Light yellow: The surrounding content has been detected as AI, which has put the highlighted content under suspicion.
• Orange: The content has robotic patterns.
• Red: The content has a high AI probability.

Now let’s see how BrandWell performed in my tests.

BrandWell AI Content Detector vs Raw AI-Generated Text

BrandWell AI content detector gave incorrect verdicts to all the AI-generated samples.

It labeled three as human and returned “Hard to tell” for the other three.

For example, I asked Claude to give me an output based on this prompt:

“Explain how bread baking works from a scientific perspective, covering what happens to the dough at each stage, from mixing through fermentation, shaping, proofing, and baking, and why each stage matters for the final texture and flavor of the loaf.”

Then, I copied the content as is and pasted it into BrandWell AI detector, and the image below shows its verdict.

BrandWell classified Claude-generated text as human when in reality it should have been flagged as 100% AI. I pasted the same Claude-generated text in the GPTZero AI detector, and it correctly showed the content as 100% AI-generated.

As you know, the samples were generated entirely using AI with simple prompts and even had obvious AI patterns. It should have been very easy for BrandWell to call out the samples as AI-generated. But that didn’t happen even once.

Here’s how BrandWell did on text generated by ChatGPT:

BrandWell failed to correctly identify even a single AI-generated sample. In contrast, notice how GPTZero rated the samples.

Here’s a PDF containing all the prompts, AI-generated samples, and screenshots of BrandWell AI detection results. The PDF document also contains screenshots of GPTZero AI detection results on the same samples.

Verdict: BrandWell failed on all six AI samples I tested and is therefore not recommended.

BrandWell AI Content Detector vs Human-written Text

BrandWell’s performance on human-written samples was better, but not entirely. 

The first sample I scanned, which was a BBC news article from 2016 (6 years before ChatGPT launched), was wrongly flagged as AI by BrandWell.

I then went ahead and scanned the same BBC news article from 2016 through the GPTZero AI detector, and it correctly identified the content as 100% human.

The second sample was a Guardian news article from 2019 (3 years before ChatGPT), but BrandWell couldn’t decide whether it was AI or human.

At the same time, GPTZero again correctly identified this article (as well) as 100% human.

Except for the two mentioned above, BrandWell correctly identified all the other samples as human.

GPTZero, on the other hand, was correct on all eight.

Please refer to this PDF to see all the screenshots I took of BrandWell AI detector performance on human-written samples.

Some Errors I Came Across When Testing BrandWell AI Detector

I also found that BrandWell starts throwing random errors without explaining what went wrong.

For example, BrandWell refused to scan content from a news article by Reuters, citing the reason as “Required fields missing.” I tried tracking down the source of the error but couldn’t. BrandWell’s unclear error description wasn’t of any help either.

On another occasion, BrandWell refused to scan, citing a network error as the reason when in fact my internet was working fine.

Verdict: BrandWell has a medium accuracy rate on human-written samples with the potential of being incorrect.

How Much Does BrandWell AI Detector Cost?

The AI detector is not the core product of BrandWell. It is fully free to use. There’s a limit on how many words you can scan at once, though.

It asks you to upgrade for scanning larger texts. But there’s no pricing page for the AI detector on the website.

When you paste text in the AI detector’s text box and it exceeds 2500 characters, the word counter turns red and asks you to “Upgrade for 60,000 word scans.”

When you click that message, an offer appears for the price of $199/year.

You are offered not only the AI detector, but the entire suite of tools packaged as WriteWell.

GPTZero: Most Accurate AI Detector

BrandWell AI detector is very problematic. First off, it’s entirely incorrect against AI-written text. Its accuracy rate on human-written content isn’t completely reliable either.

The tool also doesn’t show you a score or percentage. It simply gives you a verdict. 

In short, BrandWell is not a reliable tool to use if you’re scanning academic or marketing samples, as the verdict can be totally wrong, which someone can use to falsely accuse. 

AI detection is a sensitive matter and should only be left to dedicated and highly accurate tools like GPTZero.

GPTZero launched shortly after ChatGPT, and its accuracy rate has only increased since. Today, with over 17 million users worldwide, including 1 million educators, and a 99% accuracy rate, GPTZero is the most accurate AI detector in the market. Both independent benchmarks and our own testing have proven this countless times.

There’s a generous free plan with 10,000 credits that renew monthly.
