Agent skill
One sentence to your agent.
One finished video back.
Riffkit ships as an open-source skill your AI assistant can run end to end. Paste one line into Claude Code, Cursor, or any agent that reads a URL — then ask for riffs in plain language.

A real session, start to finish.
One sentence, one “ok”, and the riff below — the dress is from the product library, the dance hits the source BGM’s beats, and not a single frame of the source video is reused.
How it works
Four beats, zero forms.
Say it in one sentence
“Riff this TikTok into a video for my product: tiktok.com/@…/video/… — she wears the Black Fringe Dress from my product library, keep the BGM, hit the beats.”
It drafts the plan
Your agent studies the source’s winning formula — hook, pacing, beat grid — and shows you a choreography-level creative plan. You reply “ok”.
The riff renders
Riffkit generates brand-new footage around your product and character, locked to the formula. Zero frames reused from the source.
Delivery, post-ready
Minutes later: download link, suggested caption, hashtags, and a strategy recap explaining why the video is built the way it is.
What your agent delivers
Everything you need to hit post.
A finished video
Burned-in subtitles, beat-matched BGM, cover frame — post-ready, not a rough clip.
Caption + hashtags
A suggested caption and tags written from the actual creative plan, ready to paste.
A strategy recap
The agent explains the source’s formula and how your riff exploits it — so you learn while you ship.
Your product, your character
Reference your product library by name. Use your digital character or let the AI cast one.
Where this goes
Put your agent on a schedule.
The demo above is one riff. The real play is a standing order: every morning your agent scouts winning videos worth riffing, remakes the best one with your product, preps the caption and hashtags — and you do one thing: look, and post. Riffkit is the rendering engine that makes the loop close.
The skill is MIT-licensed and lives at github.com/riffkit/skill — also listed on ClawdHub.
Questions
The things agents’ humans ask first.
Which agents can run it?
Claude Code, Codex, Cursor — any assistant that can read a URL and make HTTP calls. No MCP server and no local models: the skill is a thin layer over Riffkit’s hosted engine.
How does my agent sign in?
Device authorization: your agent shows you a riffkit.ai link and a short code, you approve it in your own browser, and the session stays on your machine. Your agent never sees your password.
What does it cost?
Signing up includes free seconds, so your first riff costs nothing. After that, plans start at $99/mo and rendering is billed by the second.
Can it run on a schedule?
Yes. Agents that support scheduled tasks can run a daily loop — pick a winning video, riff your product into it, prep the caption and hashtags, and wait for your ok. One person becomes a content pipeline.
