Our verdict
Editor's assessment
Stealth Writer is the stronger overall performer in this matchup. Its bypass rate (89.5%) is higher than StealthGPT's (82.9%), and it wins against 5 of the 5 detectors where there is a clear winner. It finishes 13.0 points ahead on overall score.
StealthGPT is not a bad tool. However, its penalty load of 9 points (meaning drift, length inflation, length deflation) is significant, meaning it is more likely to alter what your text actually says.
For most use cases, Stealth Writer is the better pick.
