Microsoft Advertising is testing Copilot Audience Generation, a new feature available in a closed beta for Audience campaigns in the US, Canada, UK, and Australia. Advertisers can use natural language to describe their ideal customer, and Copilot will generate a custom AI-driven audience along with recommended segments.
Among the key elements, the new help page outlines a workflow that involves entering the desired audience description in the ‘Who’s Your Target Audience?’ section, reviewing AI-generated and recommended segments, refining the audience as needed, and saving the selections. The Copilot uses Microsoft’s audience intelligence and privacy-safe first-party signals.

Advertisers should note the limitations: no exclusions, no LinkedIn audiences, reports-only visibility, no cross-account sharing, and a potential delay of up to 72 hours before audience activation.
The feature is specific to Audience campaigns, with other campaigns unsupported.
