ChatGPT makes the mood boards and images. Claude writes your rules and keeps them in a Project. You pick and approve. The cheat sheet gives you the first three prompts in full and the whole plan on a few pages you can keep open while you work.



Also inside: what it costs (Claude and ChatGPT both have free plans; prices checked Oct 25, 2026), what prompts 4 to 8 do, and a page on the full book.
We sent Claude the same request twice: once in an incognito chat with no files, once inside a Project that holds the brand guide. Without the guide it picked a deep green background, an italic serif, a coffee emoji and seven hashtags. Inside the Project it used the brand’s colors and fonts, left a marked spot for the real logo file, and flagged its own blank farm name instead of making one up.
Halverly Coffee is a made-up sample brand. Real chats in claude.ai, Oct 20, 2026; layouts built from Claude’s written specs.

You make everything yourself and want ChatGPT and Claude to stop guessing at your colors and fonts.
More than one person posts. You want one written set of rules that every person and every AI chat follows.
The cheat sheet is the short version of Brand in a Weekend, a 37-page book from The Brand Bet. The book has prompts 4 to 8 in full. It’s $24, and new subscribers get it for $15 during their first 14 days. You don’t need it to use the cheat sheet. Not affiliated with OpenAI or Anthropic. ChatGPT and Claude are trademarks of their owners, named here only to describe the tools.
What happens next: we send you one email. Click Confirm in it and the cheat sheet opens right away (check Promotions if you don't see it). After that, The Brand Bet newsletter lands every Sunday with one real brand decision, the numbers that followed, and a move you can borrow.
