Tone presets vs. custom voice

Six presets, and how to write a custom voice prompt that the AI actually follows.

The six presets

Avago ships with six tone presets that cover most small-business needs:

  • Professional — measured and credible, good for trades and B2B.
  • Friendly — approachable and warm, good for local services.
  • Confident — direct and assured, good for a strong hero.
  • Warm — gentle and personable, good for care and wellbeing.
  • Concise — short and punchy, good for scanning.
  • Playful — light and informal, good for relaxed brands.

Pick one and the AI writes every rewrite in that register while keeping your facts intact.

Writing a custom voice prompt

When the presets don't capture how you sound, write a custom voice. The trick is to be concrete and to give examples:

  1. Describe the voice in a sentence — "plain-spoken, dry humour, never salesy".
  2. List a few do's — short sentences, British spelling, address the reader as "you".
  3. List a few don'ts — no jargon, no exclamation marks, no "world-class".
  4. Give a sample line the AI can imitate.

The AI follows a custom voice the same way it follows a preset — across every rewrite on the site.

Common mistakes

Custom voices fail in predictable ways:

  • Too vague. "Make it engaging" tells the AI nothing. Name the traits.
  • Contradictory. Asking for "formal but really casual" leaves the model guessing.
  • No examples. A single sample sentence does more than a paragraph of adjectives.
  • Fighting the facts. Voice changes the delivery, not the content; it can't add claims your sources don't support.

Set your voice once, early. Everything you write or rewrite afterwards inherits it, which keeps a multi-page site sounding like one business rather than several.
