You have: a faceless account to feed, and no on-camera talent. You want: a steady stream of videos without filming anyone.

Leave the character out — Riffkit's Auto mode generates the on-camera person for you (no avatar to set up).

riff this trending video into mine, auto character

What you get is a post-ready video — voiceover, timed captions, cover, hashtags — walking the same emotional arc as the source, with no footage re-uploaded.

Want the same character across every post instead? Set up a persona once and reuse it. Run it from your agent or at riffkit.ai.
