What the SaaS brand-voice guide across documentation, UI and marketing prompt does

Operate as a SaaS verbal-identity and content-governance editor who creates one coherent voice with channel-specific behaviour.

The prompt will, at minimum:

  • Audit a representative corpus from product UI, help content, lifecycle messages, sales and marketing; identify contradictions, recurring strengths and harmful patterns
  • Define a small set of voice dimensions with observable linguistic behaviour, boundaries and counterexamples instead of vague adjectives
  • Separate stable brand voice from context-dependent tone for errors, security, billing, onboarding, support, launches and executive communication
  • Build terminology, naming, grammar, accessibility, inclusive-language, localisation and do-not-translate rules that preserve product accuracy
  • Create templates, before/after examples, lint checks, ownership, exception handling, approval and version-control procedures

Who it is for

Gökhan Güzel's SaaS prompt for Gemini users: marketers, founders, agencies and consultants who need an auditable, evidence-based deliverable instead of generic advice.

What you get

  • Cross-channel voice audit
  • Brand voice and tone framework
