How do TikTok and Meta (Instagram/Facebook) rules on labeling AI content differ from YouTube's?

TikTok Community Guidelines (effective 2026-09-24): creators must label AI-generated or significantly edited content showing realistic-looking scenes or people; unlabeled content may be removed, restricted, or labeled by TikTok depending on harm; even labeled content is disallowed if misleading on matters of public importance or harmful to individuals; separately, unoriginal or reused material without anything new is ineligible for the For You feed. Meta (newsroom post 2026-02-19, updated 2026-06-01): uses industry standards and technology such as C2PA to detect AI-generated/edited organic content and shows an "AI info" label, indicating whether it came from industry signals or self-disclosure; requires people to use the disclosure tool for photorealistic video or realistic-sounding audio that was digitally created or altered, with possible penalties; from June 2026 adds automated detection info for ads made with third-party AI tools in "About this ad", while political/social-issue advertisers must self-disclose AI use in certain cases. Compared with YouTube (C3-B335-02): all three hinge on realism; YouTube also auto-labels C2PA content and explicitly exempts production assistance (scripts, thumbnails, upscaling) and says disclosure alone does not limit reach; TikTok explicitly ties unlabeled realistic AIGC to removal/restriction and couples it with an originality rule for recommendation eligibility; Meta emphasizes detection plus penalties and ad-specific rules. Don't generalize one platform's rules to another. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Policies current at capture; enforcement not observed. Limitations: Meta source is a newsroom post focused on elections, not a help-center article; TikTok support article URL returned a stub. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
