CEO Max Spero announced a detection system for Gmail that identifies AI-generated messages via red and green badges. The tool tags cold emails as either human or machine-written and allows users to divert fully AI-generated content to the spam folder or skip the inbox entirely. Pangram's false positive rate is below 1 in 10,000 for text flagged as AI, a metric cited by Spero as evidence of high reliability.

The company implemented a "Zero Data Retention" policy for all email scans, ensuring no inbox data is stored after processing. While such privacy protections are typically limited to enterprise clients, Pangram extended the policy to all users due to the sensitive nature of email data. The labeler allows recipients to filter machine-written "slop" based on a choice of labeling or automated removal.
