Eric Siu's $50k AI Marketing Playbook: 32,000 Lines of Code Released for Free

For marketers and tech startup founders, spending thousands of dollars on AI courses only to learn basic prompt engineering is a frustratingly common experience. Eric Siu, the CEO of marketing agency Single Grain, has just disrupted this trend by open-sourcing his entire AI marketing codebase—32,000 lines of production-ready code that his agency would typically charge $50,000 to deploy.

Not Just "Demo" Code, But Battle-Tested Solutions

Siu is transparent about the current state of open-source AI marketing tools: most of them are merely wrappers around simple prompts. They look good on GitHub but fail in real-world scenarios.

Single Grain's newly released repository is entirely different. This isn't theoretical code. It is the result of daily, rigorous operational use. They only cleaned up and published the workflows that had run flawlessly for at least three months in production across hundreds of real client campaigns. Currently, the repository features 17 distinct skill categories containing over 32,000 lines of robust code.

6 High-Value AI Capabilities You Can Use Today

The latest repository update includes six powerful new skills that are essential for any content creator or sales professional:

1. •Automated Long-to-Short Video Clipping: Have a 60-minute podcast? This tool uses Whisper for transcription and Claude to identify the most engaging "hooks." It then automatically utilizes FFmpeg to generate 3-5 high-quality short clips—all for less than $1 in API costs.
2. •Horizontal to Vertical (TikTok/Reels) Conversion: Beyond simple cutting, this script employs facial recognition to automatically crop landscape videos into vertical formats, adding dynamic, TikTok-style flashing subtitles.
3. •One-Click Website Cloning: Input any URL, and the system generates an identical Next.js replica. This is an incredibly powerful tool for competitive research or rapid prototyping.
