What it is
Claude Opus 5.5 built a marketing engine that casts an AI avatar, invents a product, films UGC reels with Higgsfield, and posts a full week to Instagram through Blotato - for about $7 a reel instead of $200.
Built with Claude Code.
How it's built, step by step
- Why UGC, and why you need so much of it - Building the product isn't the hard part anymore, because AI can do that for you. The hard part is getting people to actually see it.
- How the marketing engine works - Think of the engine as a tiny marketing team with three members.
- Get your Higgsfield and Blotato API keys - Before Opus writes a single line, you need two keys. This takes about two minutes.
- Set up Claude Code with Opus 5.5 - Then type /mcp. Higgsfield's MCP was sitting right there, but switched off on purpose. An MCP only works while you're sitting there chatting with Claude, and I wanted an app that runs on its own from a button.
- The build prompt - The most important thing before generating a single screen is a proper spec: a clear description of every feature, every screen, and what "finished" actually means.
- What Opus built in 1 hour and 6 minutes - The whole build took 1 hour, 6 minutes and 37 seconds.
- Cast the AI avatar - Click Create avatar. Instead of one big text box, you get a little casting form: age range, gender, style, setting and vibe.
- Invent the product - In real life you'd upload your own product photos here. To show what's possible, I let AI invent the entire product.
- Film the first UGC reel - In Reel Studio, Dayshift and Marcus were already picked since they're the only ones we have. Platform: Instagram. Length: 24 seconds. Angle: let Opus choose. Click Write script.
- Redesign the app with the Mobbin MCP - The engine works, but the app looked generic and still had that invisible-text bug. That matters because this is a tool you'll open every single day, and if it looks cheap, you start trusting its output less.
- Plan and post a full week of reels - This is the part the whole engine was built for. In Content Week I picked Dayshift, Marcus, and seven reels starting tomorrow.
