TikTok used Cannes Lions to unveil Symphony Agent, an AI ad agent that pairs advertisers' campaign goals with insights from the app's top content and trends to match brands with relevant creators and build custom video ads. The agent ships with safeguards like AI labels, invisible watermarks, and content-moderation filters, and integrates across TikTok's Symphony Creative Studio, Content Suite, and brand-creator platform TikTok One. TikTok also folded Symphony into Dentsu's AI SaaS platform Zoyumi, giving the agency's clients direct access to tools like image-to-video creation, with caption removal, dubbing, and digital avatars coming later. Advertisers can now build custom creator networks of vetted creators, employees, or brand advocates within Content Suite, with TikTok launching its first such network with Starbucks later this summer to promote the chain's “Green Apron Creator Program.”
