What is Synthetic content?

Synthetic content is any media — images, video, audio, or text — generated or substantially modified by AI rather than captured from the real world. The category covers AI UGC photos, virtual influencers, AI-generated voiceovers, lip-synced talking-head videos, AI-written articles, and deepfake-style face swaps. Synthetic content sits on a spectrum: at one end, fully generated assets (an AI persona that does not exist in physical reality), and at the other, hybrid content (a real photo enhanced with AI background replacement or generative fill). Disclosure rules are evolving across jurisdictions and platforms — Meta, TikTok, YouTube, and LinkedIn now require AI-content labels on certain types of synthetic media, the EU AI Act mandates clear disclosure for AI-generated content that could mislead, and the FTC has issued guidance against using synthetic content to fabricate endorsements. The industry has converged on technical provenance standards (C2PA, SynthID, IPTC AI metadata) that embed cryptographic signatures into synthetic assets so platforms and viewers can verify origin. Brands using synthetic content for advertising should treat disclosure as a competitive moat rather than a compliance burden — transparent AI labeling correlates with higher trust and engagement in audience studies, especially among younger consumers who already assume most online content is partly synthetic.
