🧠 Introduction
WriteHuman brands itself as a reliable AI humanizer, claiming a newly updated model specifically built to bypass GPTZero. The website also includes its own AI detector and promises smoother, more human-sounding rewrites.
But does it actually deliver on those claims?
We tested WriteHuman's humanizer against major AI detectors — GPTZero, ZeroGPT, and Turnitin.
🚀 What Is WriteHuman?
WriteHuman is a web-based tool that offers:
- An AI humanizer
- An AI detector
- AI Image Detector
- Word Counter
They also claim to have millions of users, though there's no verifiable evidence of that. If those numbers were accurate, WriteHuman would rank among the top 5 tools — but based on traffic, visibility, and performance, it's not even close to leaders like QuillBot, Undetectable AI, or TwainGPT.
🧪 Humanizer Test Results
We used WriteHuman’s default settings and tested it with a 100% GPT-5-generated text.
The Results:
| Detector | Result |
|---|---|
| GPTZero | ❌ 100% AI |
| ZeroGPT | ❌ 70% AI |
| Turnitin | ❌ 100% AI |
| WriteHuman | ❌ 96% AI |
Even though the output was slightly improved in ZeroGPT, it completely failed GPTZero and Turnitin, and even scored poorly in its own built-in detector.
🎉 But... They Claimed a GPTZero Update?
Yes — WriteHuman advertises an enhanced model (as of September 25, 2025) optimized for GPTZero.
🎉 New September 25, 2025: Enhanced model updated for GPTZero 🎉
But our tests prove that this update either isn’t effective. A 100% GPTZero score post-humanize is a total failure.
✅ Final Verdict
WriteHuman is easy to use and offers free rewrites, but the quality and detection results make it unreliable.
Pros:
- Free to try
- Updated interface
- Includes its own AI checker
Cons:
- ❌ Failed all major detectors
- ❌ Claimed updates don’t seem to work
- ❌ Own detector flagged its output as AI
- ❌ Rewrites lacked fluency and originality
If you're serious about bypassing GPTZero, ZeroGPT, or Turnitin, WriteHuman falls short.
✅ Use TwainGPT instead — the best AI humanizer in 2025.
📌 FAQ
Can WriteHuman bypass GPTZero or Turnitin?
No. In our tests, it failed to bypass GPTZero and Turnitin.
Does WriteHuman really have millions of users?
They claim to — but based on visibility and market presence, it’s highly doubtful.
What's a better alternative?
TwainGPT: An undetectable AI humanizer that consistently bypasses all major AI detectors.
