FAQ

Common questions

Do these prompts work in the free ChatGPT tier?

Yes, but you'll get better results on Plus with GPT-5 and memory enabled. Free-tier models sometimes truncate long structured outputs.

Can I use these prompts in Claude, Gemini, or Grok?

Mostly yes. Prompt patterns transfer across frontier models. You may need to shorten role framing for smaller models.
