Not a horizontal ad re-cropped. Every keyframe is composed for vertical from the start — products framed for the format, captions positioned for safe-zone, motion paced for thumb-stopping scroll.

Connect your TikTok account once. Generated videos schedule and publish straight to TikTok with caption, hashtags, and cover frame — no download/upload step in the middle.
