Walter Writes AI Detector Review: Test Accuracy on 3 Texts
Not sure if Walter Writes AI Detector is worth your time? You might worry it flags human text or misses AI content.
I ran multiple tests and looked at its tools and pricing to give you a full picture.
Keep reading to find out how it actually handles different types of writing.

What Is Walter Writes
Walter Writes is a platform that combines AI humanization with detection tools. It is designed to help users create content that sounds natural and human-like while also verifying whether AI generated the text.
What Is Walter Writes AI Detector
Walter Writes AI Detector is a tool that identifies whether content was written by AI models such as ChatGPT, GPT-5, Claude, or Gemini.
The detector works by analyzing sentence structure, linguistic patterns, repetition, and burstiness to calculate an AI probability score. supports detection in over 20 languages, including English, Spanish, French, German, and Portuguese, and it can highlight AI-generated sentences or mixed-content sections to give a detailed overview of the text’s origin.
Extra Tools of Walter Writes
Beyond AI detection, Walter Writes offers AI humanizer. The feature can rewrite AI-generated content to sound more natural and human-like.
How Accurate Is Walter Writes AI Detector
The official site claims it can accurately detect content from models like ChatGPT, GPT-5, Claude, and more, giving a probability score almost instantly.
I decided to put these claims to the test and see how well the detector performs in different text scenarios.
To keep it clear, I tested three types of text: pure AI content, a mix of human and AI writing, and AI text that’s been humanized using QuillBot.
Test 1: Pure AI Text
Setup:
For the first test, I generated a text entirely with ChatGPT-5, making sure no human input altered it.
This gave me a clean sample to test the detector’s baseline accuracy.
Results:
Walter Writes flagged it as 100% AI.

Observations:
This result aligns with expectations. The detector clearly identified the text as fully AI-generated, showing it can accurately pick up on AI patterns when no human intervention is involved.
Test 2: Mixed AI + Human Writing
Setup:
Next, I created a hybrid text. I took a paragraph written by a human before ChatGPT existed and then had ChatGPT-5 continue it.
The resulting text had 187 human-written words (41%) out of 454 total words.
Results:
Walter Writes scored it as 50% AI.

Observations:
This is fairly accurate considering the mix. The detector recognized that part of the content was AI-generated.
It demonstrates that Walter Writes can handle texts that aren’t purely AI, giving a more nuanced assessment.
Test 3: Humanized AI Text by QuillBot
Setup:
For the final test, I took the 100% AI text from Test 1 and processed it through QuillBot’s advanced humanizer.
This tool rephrased the AI content to sound more natural and human-like.
Results:
Surprisingly, Walter Writes still flagged it as 100% AI.

Observations:
This shows that even when AI text is humanized, Walter Writes can detect underlying AI patterns.
While the humanizer improved readability and flow, the AI fingerprint remained strong enough for detection.
Pros and Cons of Walter Writes
Pros:
Simple interface: Clean, easy to navigate—just paste or upload text and get results quickly.
Fast processing: Even longer texts are rewritten or checked in seconds.
Multilingual support: Humanizes and detects AI text in over 80 languages.
Cons:
Limited free trial: Only a small number of checks are available before a subscription is needed.
Basic plan restrictions: Word count limits can be tight for longer content.
Walter Writes Pricing
Walter Writes offers both free and paid options.
Free Trial
The free AI detector can be used without a subscription, but it comes with limits on word count(300 words) and the number of checks per month.
Paid Plan
The Starter plan costs $8 per month (billed $96 annually) and allows up to 30,000 words per month, with a maximum of 750 words per request. The Pro plan is $13 per month (billed $156 annually), raising the limit to 70,000 words per month and 1,500 words per request.
Paid plans also unlock additional benefits like enhanced AI detection strength, advanced content styles, and priority support.
Can You Bypass Walter Writes AI Detector
The truth is, nope, it’s trickier than just swapping a few words here and there. You might try simple rewriting or using tools like QuillBot’s advanced mode, but as we saw in Test 3, it still flagged the text as 100% AI. Basically, anything above 20% AI is risky—so casual edits usually aren’t enough.
That’s where a professional humanizer comes in. EssayDone Humanizer is one of those tools that actually works. It doesn’t just swap words; it tweaks sentence structure, varies vocabulary, and changes the flow so your text reads like a real person wrote it.

Tested it myself using the 100% AI text from Test 1. After running it through EssayDone, the AI score dropped all the way to 8%! That’s huge—it shows that with the right tool, you can seriously reduce AI detectability while keeping your writing clear and natural.

FAQ
Is Walter Writes 100% accurate?
Not really. Walter Writes does a great job detecting AI content, especially pure AI text, but it’s not perfect. Mixed human-AI texts or heavily humanized AI can get tricky, so always treat the results as a helpful guide, not a guarantee.
How to bypass Walter Writes AI detector?
Simple rewriting usually isn’t enough. To lower AI detectability, you need a professional humanizer like EssayDone, which restructures sentences, varies vocabulary, and adjusts flow. Done right, it can bring AI scores down to a safer level.
Will my professor use an AI detector?
It depends. Many universities use tools like Turnitin, GPTZero, or even Walter Writes for essays and papers, but not every professor checks every submission. Still, it’s smart to assume they might.
Can I use AI detectors on my own work before submission?
Yes! Running your work through a detector can help you see if it reads too AI-like and gives you a chance to adjust before turning it in. Think of it as a self-check tool.
Are AI detectors legal?
Absolutely. AI detectors are just software tools for analyzing text—they don’t violate laws. You can use them freely for educational or professional purposes.
Is Walter Writes AI Detector free?
Yes, but only with limits. The free version lets you check a small amount of text each month. Paid plans increase word limits, add advanced features, and give priority support.
Conclusion
So, that’s our deep dive into Walter Writes AI Detector.
We went through its accuracy with pure AI text, mixed writing, and humanized AI, looked at pricing, extra tools, and even explored ways to reduce AI detectability.
