Google's 2026 AI Brief announcement describes natural-language guidance for AI Max: desired messaging, phrases to avoid, matching boundaries, and audience-specific emphasis. Advertisers can preview sample assets and searches, then give feedback.
The demo applies a fictional 'no price claims' rule to preview copy. The announcement described a staged English-language rollout, so availability varies by account.
A brief does not guarantee brand-safe output. People should check forbidden claims, evidence, and search scope before launch.
When to use
Use it to guide automated messaging and matching; confirm account availability and inspect previews.
