Riffkit

Riffkit is an AI video tool built for e-commerce sellers, marketers, and founders who need post-ready short-form ads in minutes instead of days. If you have ever stared at a blank editing timeline wondering why your competitors' videos take off while yours stall, Riffkit is designed to close that gap.

Give it one winning short video — a TikTok link or your own upload — and Riffkit extracts the emotion formula that made it perform: the hook that stops the scroll, the pacing that keeps viewers watching, and the emotional beats that drive engagement. Then it generates a completely new video around your product, your character, and your language, with support for English or Spanish. No source footage is ever reused: you riff the formula, not the video, so your ad stays original while following a proven structure.

What you get is a post-ready short video with a matching caption and hashtags, an optional digital character and product placement, and native captions in English or Spanish. Analysis is free — you only pay for the rendered video seconds you actually use, which makes it easy to test ideas before committing budget.

Riffkit is built for TikTok Shop sellers, DTC brands, UGC and creative agencies, and founders promoting their own products. In fact, Riffkit's own launch videos are made with Riffkit.
