Google Discover bug exposes internal discover.aigc domain and raw AI summary code

gaganghotra_ · x · 2026-11-05

Several SEO community members spotted an anomaly in Google Discover: instead of rendering an "AI Summary" card, the feed exposed the raw request code, revealing an internal domain discover.aigc.

Per @gaganghotra's analysis, the domain is resolvable only by Google's internal servers and provides all information for AI summary clusters via IDs; the user's Discover feed sends a request to a Google server to fetch AI summary text for the card. The bug appears to be a rendering failure showing raw code to users — likely just a few flipped variables that a Googler can fix. Another participant noted the domain in the screenshot is a textbook case of scaled content abuse, questioning how it got into Discover at all.
