Summary

Founder automates entire marketing workflow using Codex agents and GPT-5.6 to scrape competitor content, extract scripting patterns, and generate high-performing content—proving AI excels at replication over creation when given quality examples.

Key Takeaways

  1. AI content generation fails without exemplars. The breakthrough: give agents access to databases of high-performing creator scripts so they can pattern-match and replicate success rather than generate from scratch.
  2. Built a /scrape-creators skill that pulls top 10 videos, transcripts, and raw MP4s from any Instagram creator into a Notion database in 2-3 minutes, eliminating manual competitive research.
  3. Codex Skills system enables chaining workflows—scrape creator content → extract scripting patterns → feed patterns to content generation agent → output brand-aligned scripts, creating a closed-loop content factory.
  4. Shifted co-founder from engineering to marketing because incremental value of marketing automation exceeded engineering value with Fable AI running 24/7 on coding tasks—measurable ROI driving resource allocation.
  5. Agent-powered B-roll discovery: search YouTube for contextual video segments (e.g., 'find Alex Hormozi walking outside') to auto-populate compilation video editing—outsources asset hunting to AI agents.

So today before we dive into the workflows I just want to kind of give the audience here a quick explanation of what codeex is. On the left here we have our chats and we also can organize the chats into projects if we want. And for example, this is the agent native podcast. And so I have all m…
