Start from real examples
Collect three to five pieces of writing that sound exactly like you: a great email, a website section, a post that did well. Paste them in and ask the AI to analyse the voice.

Here are examples of our best writing.

Describe the voice as a guide with:
- 5 "we always" rules and 5 "we never" rules
- Typical sentence length and reading level
- Words we use, and words we'd never use
- One example sentence that's on-brand and one that's off-brandUse it everywhere
Edit the guide until it's right, then paste it at the top of every marketing prompt or save it in custom instructions or a project. Review the first few outputs against it and tighten any rule that gets ignored.
Tip: "Never" rules work best when they're concrete: "no exclamation marks" beats "don't be too excited".
