TikTok’s AI‑detection systems scan for:
Visual inconsistencies (weird face‑meshes, unnatural lighting, or cloned‑style lip‑sync).
Audio patterns that match voice cloning (e.g., a creator’s voice in places they never spoke).
If a video is identified as AI‑generated but not labeled, TikTok can auto‑flag it for review, remove it, or downgrade its reach even if the disclosure toggle is technically on.
