Brand guidelines for ChatGPT

How to make ChatGPT follow your brand guidelines.

Pasting a PDF into a chat does not train ChatGPT on your business. A custom GPT and a brand MCP with your voice rules, approved facts and forbidden claims does, for every teammate, every time. I build and test them.

01 What you get

What "training ChatGPT on your brand" really means.

You do not retrain the model. You give it the right context, in the right shape, every time.

  • Voice rules with real before and after examples
  • Approved facts: numbers, names, dates
  • Claims it must never make
  • Prompts for the content your team makes weekly
  • A custom GPT and a brand MCP with the same rules
  • A blind test: drafts with and without, scored
02 Proof

Teams that write with AI, on-brand.

Deepsea Networks: before, 8 of 16 AI drafts broke a hard brand rule. With the brand system loaded, 0 of 26 (my blind test, 08.10.2026).

03 How it runs

From your brand to a GPT that follows it.

You test it on your own drafts before handover.

Can I train ChatGPT on my company data?

For brand work you do not need to fine-tune a model. A custom GPT or brand MCP with your rules and facts gives better, safer results.

What is a good ChatGPT prompt for brand voice?

One that points to your rules and examples rather than adjectives. With the GPT set up, "write a LinkedIn post about X" is enough.

Does it work with Claude too?

Yes, the same rules power a Claude skill. Brand guidelines for Claude.
