AIGC disclosure is the notice that generative tools shaped the video. On TikTok that usually means two places: a line in the caption, and on-screen text for the full duration when a synthetic person or scene is visible.
A usable caption line
"Parts of this video were created with AI." The hashtag many teams also keep is #AIGenerated. Translate the sentence for the audience. Do not drop the idea because the caption is already long. Folding hashtags in after the sentence, then truncating, is how a label survives a character cap. Truncating first deletes the label.
What the label does not do
A disclosure does not make a medical claim acceptable, and it does not make a fake "today only" discount acceptable. It tells the viewer the picture was synthesized. The words around the product still have to be ones you can stand behind. TikForge can remind you when the label is missing. It cannot promise the upload will be approved.
When to add it
Add it before you generate the final cut if you already know the presenter is synthetic. Adding it after a takedown is the expensive version of the same sentence.
