Brand Voice
Define your brands tone, terminology, and writing rules so the AI stays on-brand.
Brand Voice lets you define how the AI writes content. You can set guidelines for tone, terminology, forbidden words, and language-specific instructions. These settings are applied per site, so each site can have its own voice.
You can manage Brand Voice in the control panel under CoPilot → Brand Voice.

Voice & Style Guidelines
Describe your brand's tone and writing style. This is the main instruction the AI follows when generating or editing content. Be as specific as you like — the more detail you provide, the more consistent the output.
Examples:
- "Write in a friendly, professional tone. Use short sentences. Avoid jargon."
- "Our voice is bold and direct. We use active voice and speak to the reader as 'you'."
- "Keep it casual but informative. Think blog post, not white paper."
Glossary
Define terms and their correct usage. The AI will use these exact terms when writing content instead of coming up with its own variations.
Examples:
- "CoPilot (not Co-Pilot, Copilot, or co-pilot)"
- "Craft CMS (not CraftCMS or just Craft)"
- "content editor (not admin, user, or backend user)"
Forbidden Words
List words or phrases the AI should never use, along with suggested alternatives. This is useful for avoiding off-brand language, outdated terms, or competitor names.
Examples:
- "cheap → affordable"
- "simple → straightforward"
- "users → customers"
Language Instructions
Add language-specific writing rules. This is especially useful for multi-site setups where each site targets a different language or region.
Examples:
- "Use formal German (Sie, not du)."
- "Use British English spelling (colour, organisation)."
- "For the French site, use inclusive writing."
Per-Site Configuration
Brand Voice settings are stored per site. If you run a multi-site setup, switch between sites using the site switcher in the Brand Voice editor to configure each site individually.
If no Brand Voice is configured for a site, the AI will use its default writing style without any specific guidelines.
