Brand Voice
Set a brand voice so Babelize translations match your product's tone and style, with examples, setup steps, how the engine applies it, and best practices.
Brand Voice makes your translations reflect your brand's personality. Write a short tone and style guideline, and LLM translations follow it.
How It Works
- Set a brand voice on your project (max 300 characters)
- When a babel translates with an LLM (your own key), the voice goes into the translation prompt as tone and style instructions
- The result sounds like your brand — not a generic AI translation
Examples
| Voice Description | Effect |
|---|---|
"Casual and friendly, like talking to a colleague. Use contractions." | Translations use conversational tone |
"Professional and precise. Target audience is enterprise CTOs." | Translations use corporate language |
"Warm and encouraging. App is for language learners. Keep it short." | Translations are friendly and brief |
"Technical and precise, developer docs" | Translations preserve technical accuracy |
Setting Brand Voice
Dashboard
- Open your project
- Find the Brand Voice Prompt card
- Type your description (it saves when you click away), or click one of the Style Presets
Brand Voice is available on the Starter, Growth and Studio plans. Project editors and admins can set it.
CLI
babelize projects brand-voice <project-id>
babelize projects brand-voice <project-id> --voice "Friendly and casual"How It Works in the Engine
Brand voice applies to babels that translate with an LLM: a project set to your own key, or Automatic when it falls back to your key (see Bring Your Own Key). It's part of the same request as the translation, not a second pass, and it never overrides placeholders, tags or glossary terms. Babelize's built-in translator (dictionary and NLLB) doesn't use it.
Changing the brand voice doesn't re-translate existing text by itself. To apply a new voice everywhere, use Re-translate everything on the next babel.
Best Practices
- Keep it short — 1-2 sentences work best (max 300 chars)
- Be specific — "Professional, like a bank's mobile app" is better than "Professional"
- Check the results — review a babel's results and fix any wording in place

Glossary
Keep terminology consistent across languages with a project glossary: never-translate terms, always-translate-as rules, how the engine applies them, and plans.
Formality
Choose formal or informal address per language (Sie or du, vous or tu, usted or tú) so every translation addresses your users the same way.
