I Let Pangram Loose on My Gmail Inbox. Here’s How Much AI It Found

Pangram has added a Gmail integration that scans incoming messages for signs of AI-written text, letting users label, archive or filter emails based on its assessment. The feature matters as AI-written messages become harder to distinguish from human writing, though users must trust Pangram with access to email contents.

The integration requires Pangram’s $20-a-month individual plan and scans the 100 most recent threads, then new messages; the company says email contents are not retained or used for training. In a test of 108 threads, it marked eight as AI, 37 as human and the rest as mixed. The author’s known human-written emails and a Copilot-generated message were classified correctly, but the sample was small, short emails may go unclassified, and only the first message in each thread is checked.
