Prompt Lab
Prompts that work on a real brief. Ready to copy.
Tricks for ChatGPT, Claude and Gemini that hold up in brand and creative work — each one sourced to the vendor’s own guide — and prompts from my own productions, turned into templates you can use on any brand.
Chatbot tricks
One technique per card: what to change, a before-and-after, and a prompt you can copy.
Name the exact format and length
“Write captions” leaves the model guessing. Name the format, the columns and the character limits, and the output drops straight into your deck —…

Say what to do, not what to avoid
“Don’t sound corporate” says what you dislike, not what you want. Describe the target instead — with a copy-ready prompt.
The new-colleague test
Would a talented colleague who started this morning understand your prompt? If not, neither will the model. A two-minute check with a copy-ready prompt.
Prompts from my work
Prompts behind real AI productions, with the brand details removed so the structure works for yours.
