Pangram (AI detector)

Uncommon card · No. 82890

Pangram is AI content detection software developed by Pangram Labs. Its text detector classifies passages as human-written, AI-assisted or AI-generated. The company released Pangram 4 in July 2026. It also provides an image detector. Independent studies of earlier versions found low error rates, but also found that some AI-generated texts escaped detection when prompted to imitate human authors. For Pangram 4, the company reported a false positive rate of 0.0041%, approximately one in 24,000, on an English-language benchmark. Its use in education and publishing has prompted debate about whether detector results provide sufficient evidence of undisclosed AI use.
