Objective: Create a reusable AI prompt that codifies brand personality and audience nuances into a clear, operational brand voice guide that copywriters, marketers, and AI workflows can follow for consistent messaging.

How the Base Prompt Was Formed

The base prompt was formed through these deliberate steps:

  • Grounded the tone in three specific, non-contradictory adjectives ({{adjective_1}}, {{adjective_2}}, {{adjective_3}}) to create a distinct persona rather than generic marketing jargon.
  • Defined the explicit audience relationship via {{target_audience}} so sentence complexity, vocabulary, and empathy levels match customer expectations.
  • Structured actionable rules: mandated three core tone pillars with practical explanations to remove ambiguity.
  • Included positive and negative vocabulary lists (words to embrace vs. words to avoid) to prevent corporate buzzwords and AI clichés from creeping into copy.
  • Enforced concrete before-and-after rewrite examples, allowing writers to quickly see how generic statements transform into on-brand copy.
Note

Save the resulting brand voice guide as a system prompt or pinned project instruction. Reusing it across daily drafting tasks ensures tonal consistency across different team members and AI tools.

Tip

Pin the "words to avoid" list in your team's editing checklist or LLM system prompts—banning tired buzzwords does more to create a distinctive voice than adding new adjectives.
