StealthGPT vs Pangram: Does StealthGPT Bypass Pangram?
Yes, StealthGPT passes Pangram AI detection at an 89% bypass rate based on internal testing conducted in September of 2026 and across hundreds of documents varying from academic to professional in writing style. Pangram is notable among AI detectors for explicitly targeting AI that has been processed by AI humanizer tools, establishing its position as the pre-eminent obstacle for undetectable AI everywhere, except for StealthGPT.
The detector
What is Pangram?
Pangram, built by Pangram Labs, is an AI writing detection tool designed primarily for educational settings. Its classifier is trained on millions of AI generated documents. It is built to identify AI writing based on its distinct signaled patterns including text that has been humanized after its initial generation. Pangram can integrate directly into Google Classroom to provide educators with AI transparency reports on student submissions.
Benchmark
How StealthGPT Performs Against Pangram
Methodology:
StealthGPT tested 300 uniquely AI generated documents varying in writing style, from academic to professional, were humanized through StealthGPT and then run through Pangram's AI detector for scoring. Pangram has specifically updated its detection model to flag humanized content passing through it. The test was conducted entirely under these conditions and was conducted between July and August of 2026. The documents tested ranged in length from 500 words to 3000 words.
Results:
89% of StealthGPT's humanized outputs scored below Pangram's detection threshold and were passed as human written. That 11% was flagged or marked as unclear.

Yes, StealthGPT has a successful bypass rate against Pangram of 89% and registers as human written on Pangram's AI humanizer check. The most recent testing conducted by StealthGPT against Pangram was in September 2026.
Pangram is an AI writing detection tool designed primarily for educational settings. It is designed to target AI generated text from frontier models as well as AI text that has been humanized. Pangram can be contrasted closely to Turnitin, which primarily serves AI detection in education as well.
StealthGPT's AI humanizer rewrites AI generated content to introduce the structural variation, lexical diversity, and natural unpredictability that distinguish human writing from AI output. StealthGPT's AI humanizer is trained to target the specific signals each major detector uses and is continually updated as those detectors evolve.
StealthGPT monitors Pangram closely given its specific focus on humanized content. Formal audits are conducted at least quarterly and following any announced Pangram model updates. StealthGPT uses this same tracking model against other detectors like GPTZero.
StealthGPT is tested regularly against all major AI detection platforms. Platforms like Originality.ai that usually lead in the AI detection space receive special attention to ensure StealthGPT stays ahead.
