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

I recently tested the Pangram AI text and image detector tool within my Gmail inbox. This browser extension scans incoming messages to determine if they were written by an AI or a human. To use the Gmail integration, you must have at least the $20-per-month individual plan from Pangram. The tool scans your 100 most recent email threads and any new messages, but it does not store email contents or use them to train models.

After scanning, the Gmail Integration section of the Pangram dashboard categorizes emails as AI-written, human-written, or a mix of both. These categories can be applied as labels or automatically sent to the archive, spam, or excluded from scans. In my test, eight of my 108 emails were labeled as AI, 37 as human-written, and the rest as mixed.

None of the emails I know to be written by real people were flagged as AI-written. The tool works best on longer emails, and only the first email in each thread is scanned. Overall, Pangram seems effective in detecting AI-written emails, helping users identify and manage AI-generated content in their inbox.
