How Effective Is AI Text Humanization?
We tested AI-generated text samples before and after WriteMask humanization. Here are the real, unedited results.
Average AI detection score
Before humanization
After WriteMask
32.8% average reduction
Passed as “Likely Human”
Single-pass humanization
Sample-by-Sample Results
| Topic | Raw AI Score | After WriteMask | Result |
|---|---|---|---|
| Social media & communication | 82% | 38% | Passed |
| Climate change policy | 82% | 62% | Reduced |
| AI in healthcare | 82% | 72% | Reduced |
| Remote work evolution | 72% | 62% | Reduced |
| Education technology | 82% | 35% | Passed |
Detection threshold: scores below 50% are classified as “Likely Human.” All tests used WriteMask Standard mode with a single pass.
What We Learned
Every sample scored lower after humanization
All 5 samples showed reduced AI detection scores after WriteMask processing. The average drop was 32.8% — from 80% to 53.8%.
Best results on narrative content
Samples about social media (38%) and education (35%) scored lowest after humanization — these topics allowed for more natural voice variation. Technical/scientific content was harder to fully humanize in a single pass.
Single pass vs multiple passes
These results are from a single humanization pass. Running text through WriteMask a second time typically reduces scores further. We recommend checking your text with our free detector and re-humanizing if the score is still high.
A Note on Honesty
We publish these results as-is, without cherry-picking. Not every sample achieved a “Likely Human” verdict in a single pass. We believe transparent results build more trust than perfect-looking data.
AI detection is an evolving field. Detectors improve, and so do humanizers. We continuously update WriteMask's rewriting engine and will publish updated results as our technology improves.
For best results, we recommend using WriteMask's free detector to check your text after humanizing, and re-processing if needed.
Methodology
Samples: 5 AI-generated text passages, each 60-80 words, covering academic and general topics. Generated by AI to represent typical ChatGPT-style output.
Detection: Tested using WriteMask's built-in AI detector, which analyzes perplexity, burstiness, vocabulary patterns, and structural uniformity.
Humanization: All samples processed through WriteMask Standard mode (single pass).
Scoring: 0-100% AI probability. Below 50% = “Likely Human.” Above 50% = “Likely AI” or “AI.”
Date: April 2026. We plan to expand this study with more samples and additional third-party detectors.
