When content sounds like your site and reinforces the same entity signals, visibility improves across prompts. ## Create a brand voice 1. Select **Brand voice** from the sidebar. 2. Click **Create brand voice**. 3. Provide context — your site URL works best because Krastie analyzes your existing content and tone. Screenshot2025 09 28015725 Krastie extracts writing style, terminology, and positioning from your source material. You can also create brand voices from sample text or uploaded files. ## Use brand voice in content Apply a saved brand voice when generating or improving content: * Select a brand voice in the Content editor before generating a draft * Pass `brandVoiceId` when calling the [text](/api-reference/ai-generation#post-text) or [chat](/api-reference/ai-generation#post-chat) API endpoints Brand voice does not replace visibility strategy — it ensures the content you publish to close visibility gaps sounds authentically like your brand. ## Keep brand voice current Update your brand voice when you: * Rebrand or change positioning * Target a new audience or product line * Notice generated content drifting from your site's tone Regenerate from your website URL or edit the saved voice directly in the app. ## API access Manage brand voices programmatically via the [Brand voice library](/api-reference/brand-voice) endpoints.
