What Pangram says about itself
Pangram says it detects AI-generated and human-written content in over 20 languages. See Pangram’s website for current details.
What independent research says
Vendor figures come from the vendor’s own tests. Independent research paints a more cautious picture of AI detection in general:
- In a peer-reviewed Stanford study, seven detectors misclassified an average of 61% of human-written TOEFL essays as AI-generated, while essays by US eighth-graders were classified almost perfectly (Liang et al., 2023).
- An independent test of 14 detection tools found none above 80% accuracy (Weber-Wulff et al., 2023).
- OpenAI withdrew its own AI classifier in 2023 for low accuracy (OpenAI).
What non-native writers should know
- Some humanizer tools advertise tuning specifically against Pangram — a sign of how much detectors and rewriters chase each other.
- Its Google Docs integration means a teacher can scan shared documents directly.
- Keep version history on in Google Docs: it records how your text was written.
If Pangram flagged your work
- Ask which passages were flagged and whether other evidence was considered.
- Share your Google Docs version history.
