Voice Memo to Finished Training: The GPT + Gemini Assembly Line

Content & MarketingJan and Olly
  • “GPT is incredible at creating logical structures, while Gemini excels at turning those structures into actual readable content.” — Jan and Olly

The problem

Olly's expert knowledge for his mentorship programme (Dream 100, welcome sequences, high-ticket coaching) was locked in his head, and turning it into comprehensive written training programs manually would be enormously slow. Generic AI-generated course content is useless without structure and real examples.

The AI solution

Olly sends 2-10 minute voice messages explaining his vision for a training. Jan transcribes them and feeds the transcript into GPT with massive, detailed prompts. GPT produces the structure: why the training matters, the mindset shifts needed, and step-by-step implementation. Olly then reviews and approves the outline before anything gets written.

The approved outline goes to a second model, Gemini, which writes the actual modules one by one. The split is deliberate: GPT is incredible at creating logical structures, while Gemini excels at turning those structures into readable content. Finally they add real case studies and examples from their own world — the human layer that makes the content valuable instead of generic.

The whole process is codified in a detailed SOP with well-thought-out prompts, so it runs repeatably rather than as one-off experiments.

Results

Expert knowledge is turned into comprehensive training programs for Olly's mentorship programme from 2-10 minute voice memos; described as a game-changer for education businesses.

How to copy it

  1. Have the expert record a 2-10 minute voice message explaining the vision for one training.
  2. Transcribe it and feed it to GPT with a detailed prompt asking for structure: why it matters, mindset shifts, step-by-step implementation.
  3. Get the expert to review and approve the outline.
  4. Give the approved outline to Gemini and have it write the modules one by one.
  5. Add your own real case studies and examples, and save your prompts as an SOP.
