NEWSLETTER · EVERY FRIDAY

Practical AI workflows for ad creative, written by a guy who builds them, breaks them, and publishes the prompts.

THE DEAL

Every Friday: one real workflow from a working ad account, the paste-ready prompt that runs it, and the honest limits of what it can't do yet.

★ WHAT'S INSIDE
01 · REAL WORKFLOWS

From a working account

Swipe files that decide things. Fatigue monitors. Persona miners from real Reddit threads. Every system runs on live client work before it runs in the newsletter.

02 · PASTE-READY

The full prompts

Every issue ships the complete production prompt, not a summary of one. Copy it, paste it, run it the same afternoon.

03 · HONEST LIMITS

What it can't do yet

Every issue says where the workflow breaks. The failed renders and false alarms ship too. No hype, by house rule.
