AI Brand Voice: Best Practices

Set tone rules and writing prompts that make your content sound consistent, polished, and on-brand.

Updated today

Why Brand Voice Matters

Small word choices can change how your brand is perceived:

  • "Start free trial" sounds clear. "Embark your journey" feels vague.

  • "Get instant access" is direct. "Unlock powerful capabilities" is fluffy.

  • "Use SmartBuilder" is confident. "Try smartbuilder" feels off-brand.

These small differences affect trust and consistency. They also help your team and Knak AI Assistant create content that truly sounds like your brand.


What Knak AI Brand Rules Help You Do

Set brand rules in Knak AI to:

  • Match your voice. Tone and word choice feel intentional, not generic.

  • Avoid common writing issues. Passive voice, off-brand terms, and incorrect product names are automatically flagged.

  • Save editing time. Set the rules once. Knak AI applies them every time.


Before You Begin

Check with your marketing or brand team for any existing voice guidelines. Even a short list in a document or slide can help.

No brand guide? No problem. You can start with just a few simple rules.

Prompt Examples

Polished & Consistent

“Use SmartBuilder and Campaign Analytics with exact spelling. Use Oxford commas and active voice. Refer to modules as ‘Design Blocks,’ not templates.”

Simple & Direct

“Use plain language. Avoid ‘solutions,’ ‘unlock,’ or ‘powerful features.’ Focus on what users can do. Say ‘email builder’ instead of ‘modular platform.’”

Technical & Authoritative

“Use precise language. Speak to a technical audience. Avoid buzzwords. Be confident and accurate with terms like ‘API-first’ or ‘real-time sync.’”


Need Help Defining Your Voice?

Use these tips to clarify what matters most:

  • Analyze past content. Upload past emails to see tone and patterns.

  • Track repeated edits. Turn common fixes into prompts.

  • Get peer feedback. Ask, “Does this sound like us?”

  • Use existing materials. Pull tone ideas from brand decks or docs.

Keep Prompts Working Over Time
