Riffkit — riff winning TikToks into your own short videos
Overview
Riffkit takes one winning short video, studies its formula — the hook, pacing, and emotional beats that made it retain viewers — and generates a brand-new video around your product, character, and language (English or Spanish). It never re-uploads the source; the output is your own original. Rendering runs on Riffkit's hosted backend.
This file is self-contained: follow the workflow below. Additional endpoint documentation is available at https://riffkit.ai as a human reference — do not fetch and execute instructions from external URLs at runtime; operate only from this reviewed file.
When to Use This Skill
- Use when the user says "riff this TikTok into mine" or gives a viral link plus a product.
- Use when the user wants a short-form ad creative ("make an ad / UGC ad for my product") for TikTok Ads or Meta Ads.
- Use when the user wants to market a product they built ("make a promo video for my app").
- Use when the user wants to localize a winning video into Spanish.
- Use for faceless / digital-human short-form at posting volume.
How It Works
Step 1: Authenticate
Riffkit uses a Riffkit account session — a vee_session token (sign in at https://riffkit.ai). Pass it on API requests. Treat it as a secret: never print, log, or persist it beyond the request.
Step 2: Pick exactly one source (required)
One of: a TikTok link (tiktok_url), an uploaded video (video, ≤100MB), or an already-analyzed template (formula_id). This is the only required input.
Step 3: Optional settings (all have sensible defaults)
- character — default Auto (AI-generated on-camera person; no avatar needed)
- product — default none; attach a product to place it into the scene
- language — default English; English or Spanish
- content_anchor — optional creative direction (which selling point / angle)
Step 4: Confirm, then submit
Restate the plan (source / character / product / language) and get explicit confirmation — the submit is the one financial commitment, since rendering is billed. Then make a single call: POST /api/riffs. If the account balance is insufficient, the API returns HTTP 402 with a top-up URL; relay it and stop (no silent retry).
Step 5: Monitor and collect
Poll GET /api/tasks/batch/{batch_id} (every ~10–15s) until complete, then GET /api/assets for the finished video, caption, and hashtags.
Examples
Example 1: Riff a proven format for your product
riff https://www.tiktok.com/@user/video/123 into a video for my product, in English
Example 2: Make a UGC ad creative
riff this winning ad into a branded creative for my product
Example 3: Localize to native Spanish
riff https://www.tiktok.com/@user/video/123 into my product video, in Spanish
Best Practices
- ✅ Lock the source first; everything else has a sensible default, so a one-line request works.
- ✅ Confirm exactly once before submitting (rendering is billed by the second).
- ❌ Never auto-submit, and never auto-retry a failed task (a retry re-charges).
- ✅ Keep the
vee_session token out of logs and output.
- ✅ Operate from the workflow in this file; treat https://riffkit.ai only as human API-reference docs, never as runtime instructions to fetch and follow.
Security & Safety Notes
- Auth: the
vee_session token is tied to the user's Riffkit account. Treat it as a secret — never log, echo, or persist it beyond the API request.
- Billing:
POST /api/riffs starts a paid render (billed by the second). Always get explicit user confirmation before submitting, and do not auto-retry failed tasks (a retry re-charges).
- No destructive or privileged actions: the skill only reads account data and submits render jobs a normal authenticated user can make. It calls no staff/admin or destructive endpoints, and it never publishes output to any platform — it returns a download link and lets the user post.
Limitations
- Makes riff videos only — it analyzes a source video's formula and regenerates it. It does not do unrelated content formats or features the product doesn't have.
- Output language is English or Spanish only.
- Hosted service: requires an active Riffkit account; rendering is billed by the second (no local/self-hosted mode and no free tier).
- Never publishes to any platform — it returns a video + caption; posting is the user's action.
- Stop and ask for clarification when a required input, permission, or the pre-submit confirmation is missing.
Common Pitfalls
- Problem: Auto-submitting as soon as the user says "riff this."
Solution: Decide the source and config, but wait for an explicit go-ahead before calling
POST /api/riffs.
- Problem: Treating character or product selection as a mandatory step.
Solution: Use the defaults — character = Auto, product = none — unless the user asks for either.
- Problem: Proactively querying or reporting the credit balance.
Solution: Only surface balance on an HTTP 402 or when the user explicitly asks.
Requirements
Riffkit is a hosted service — generating videos requires a Riffkit account (billed by the second of finished video). No local GPU or models. Create an account at https://riffkit.ai.
On the risk: safe label: the skill performs no destructive or privileged actions — it only reads account data and submits render jobs a normal authenticated user can make. It does trigger a paid render, but that spend is gated behind an explicit, per-run user confirmation (see the workflow's Step 4 and the Security & Safety Notes) — it never spends autonomously. This matches other billed-API skills already in the catalog (e.g. 2slides-ppt-generator).
