💡 Pro Tips

Claude
Claude (Opus 4 / Sonnet 4)
Define the anti-vocabulary (words you never use) — it's more useful than listing approved words
Write 3 'before and after' rewrites — showing the voice is clearer than describing it
The channel adaptation section prevents the most common failure: teams treating all touchpoints as identical
Test the guide by giving it to someone who doesn't know your brand and asking them to write something — see if the output matches your brand immediately
Vague personality words ('innovative', 'customer-focused') — these describe every company
No examples of what NOT to do — the don'ts are as important as the dos
Creating a guide so long nobody reads it — one-page cheat sheet is more valuable than a 40-page manifesto
Forgetting to update the guide as the brand evolves
- What's the difference between brand voice and brand tone?Voice is consistent — your personality doesn't change. Tone varies by situation — the same brand is warmer in a welcome email than in a legal disclaimer, but both should be recognisably the same brand.
- How do I enforce brand voice across a team?Make the guide a one-pager, not a book. Run 'before and after' writing workshops. Include voice review in your content approval process. The best enforcement is a guide so clear and useful that writers want to follow it.
- Should brand voice differ across markets?The core voice should be consistent. Tone may adapt for cultural context — more formal in some markets, more playful in others. Never translate brand voice literally; localise it with native speakers who understand the brand personality.
- Can AI generate our brand voice?AI can draft a starting point, but brand voice should be validated by people who know the company deeply — founders, long-tenured employees, best customers. AI-generated voice guides often need significant editing to reflect genuine personality.
