Opinion: Pangram’s Gmail filter could send legitimate AI‑assisted emails to spam
In August the author warned that AI detectors used like spam filters provide little insight into human effort. Less than a month later Pangram, a leading AI‑detection service, launched a Gmail integration that lets users automatically archive or move to spam any email labeled as AI‑generated. The feature is promoted on Pangram’s page for the integration.
Key points
- Pangram’s Gmail add‑on can auto‑archive or spam emails flagged as AI‑generated.
- Pangram claims 99.98% detection accuracy and tops an independent study of detectors.
- Author warns legitimate AI‑assisted emails may be mis‑filtered, urging caution.
Pangram claims its detector can identify AI‑generated text with 99.98% accuracy, and an independent study that compared multiple detectors found Pangram to be the most effective. The author notes that the tool cannot judge the quality of flagged content, so legitimate AI‑assisted emails could be mis‑filtered. Two examples are shown where human‑written prompts were rewritten by AI; both versions were flagged as AI and could have been sent straight to spam.
The piece argues that treating all AI assistance as “slop” and automatically hiding such messages may push ordinary users to look for ways to evade detectors. Upcoming research on evasion techniques and more human‑like generation is mentioned for a future post.
