The State of AI Detection
In 2025, AI detection is everywhere. Tools like Turnitin, GPTZero, ZeroGPT, Copyleaks, Grammarly, Quillbot, and others are all competing to set the standard for detecting AI-generated writing. Most of them have rolled out updates targeting not just AI text, but also 'AI paraphrased' content.
This raises the question: how does TwainGPT perform against them?
TwainGPT’s Approach
TwainGPT is designed to make AI writing undetectable, natural, and human-like. Its process focuses on:
- Restructuring sentences for natural rhythm
- Expanding vocabulary to avoid predictable patterns
- Adding subtle variation to match human writing
TwainGPT is updated frequently to stay effective with the rapid updates in AI detection.
📊 Detection Results
We tested GPT-5 and Claude text against multiple detectors, then re-ran it after humanizing through TwainGPT.
| Detector | Raw AI Content | TwainGPT Humanized | Result |
|---|---|---|---|
| Turnitin | 100% AI | 0% AI | ✅ Passed |
| GPTZero | 100% AI | 1% AI | ✅ Passed |
| ZeroGPT | 100% AI | 0% AI | ✅ Passed |
| Copyleaks | 100% AI | 0% AI | ✅ Passed |
| Grammarly | 96% AI | 0% AI | ✅ Passed |
| Quillbot | 85% AI | 0% AI | ✅ Passed |
TwainGPT consistently bypassed every major AI detector tested with ease. These results show why TwainGPT is the best AI humanizer available.
