What does Riffkit do?

Riffkit analyzes a winning short video (from TikTok or your own upload) to understand its formula—hook, pacing, and emotional beats—then generates a brand-new original video around your product, character, and language. The output is a finished video with captions and hashtags, never a re-upload of the source.

What are the required inputs to use Riffkit?

You need exactly one source: either a TikTok link, an uploaded video (≤100MB), or an already-analyzed template (formula_id). Optional inputs include character (defaults to AI-generated), product, language (English or Spanish), and content_anchor for creative direction.

How is Riffkit billed?

Riffkit is billed by the second of finished video. You must get explicit user confirmation before submitting a render job, and if your account balance is insufficient, the API returns HTTP 402 with a top-up URL.

Does Riffkit publish videos to social media platforms?

No, Riffkit never publishes to any platform. It returns a download link and lets you post the video yourself.

What do I need to authenticate with Riffkit?

You need to authenticate with a `vee_session` token from your Riffkit account by signing in at https://riffkit.ai.

Overview

Riffkit - riff winning TikToks into your own short videos

Riffkit analyzes a winning short video to extract its hook, pacing, and emotional beats, then generates a completely new video applying that formula to your product or message. It renders videos on a hosted backend, delivering original content rather than modifications of the source. Use Riffkit when you've identified a high-performing short video and want to apply its retention principles to your own product. It's ideal for creating video campaigns that replicate viral patterns without copying or re-uploading existing content.

What it does

Riffkit takes one winning short video and studies its formula - the hook, pacing, and emotional beats that made it retain viewers. It then generates a brand-new video around your product, character, and language, creating original content rather than re-uploading the source. The output is your own original video, rendered on Riffkit's hosted backend.

When to use - and when NOT to

Use Riffkit when you've identified a high-performing short video and want to apply its retention formula to your own product or message.

Do NOT use Riffkit if you need to simply re-upload or redistribute the original source video - the tool is designed to create new, original content only. Avoid using it when you don't have a clear winning video to analyze or when you need real-time video generation without backend processing.

Inputs and outputs

You provide a winning short video that demonstrates effective viewer retention through its hook, pacing, and emotional structure. You also specify your product, character details, and target language.

You receive a brand-new, original short video that applies the analyzed formula to your content. The video is rendered on Riffkit's hosted backend and delivered as your own unique asset, not a modification of the source.

Who it's for

Riffkit suits users who understand what makes a video perform well and want to systematically apply those principles to their own messaging across TikTok and similar short-video platforms.
