Frequently asked questions
What is the difference between brand voice and brand tone?+
Brand voice is your consistent personality across all content: who you are. Brand tone is how that voice adapts to context: a customer complaint email sounds different from a product launch post, but both reflect the same underlying voice.
How do I maintain brand voice when multiple people write content?+
Create a written brand voice guide with specific do/don't examples and share it with everyone who writes for your brand. Use ChatGPT to help check new content against the guide before it is published.
Can ChatGPT consistently write in my brand voice?+
With enough examples and a clear voice guide, ChatGPT can approximate your brand voice well. Give it 5-10 examples of on-brand content and a description of your voice characteristics at the start of each session. The more context, the better the match.
How do I know if my brand voice is working?+
Your brand voice is working when your audience can recognize your content even without seeing your logo, when it feels authentic and consistent to your team, and when customers use similar language to describe your brand as you use in your content.
Should small businesses have a defined brand voice?+
Yes. Even a one-person business benefits from a clear voice. It makes content creation faster (you know what you sound like), more consistent (everything feels connected), and more authentic (it reflects who you actually are).
