Paste a proven reel and Riff pulls its format apart — cuts, text, audio — matches your own B-roll against it, and renders three posting-ready variations in about three minutes. Then it schedules them, counts the views, and learns which of your clips win. No prompts, no stock, no AI slop.
"I paid an editor two grand a month to clone formats by hand. Riff does it in three minutes from my own footage — and my winning clips keep getting picked first."
