Consistent brand voice reinforces how AI models understand your business. Use these endpoints to manage saved voices applied during content generation.

PUT	/:id	Update brand voice
DELETE	/:id	Delete brand voice

To create a brand voice from a website, text sample, or file, use the generate routes in Content generation endpoints:

• POST /v1/ai/generate/brand-voice/website
• POST /v1/ai/generate/brand-voice/text
• POST /v1/ai/generate/brand-voice/file

Creating from your website URL is recommended — Krastie analyzes your existing content to capture tone and entity signals.
