A voice that survives the AI that writes it

Your voice,
made machine-proof.

The Brand Voice Specification is a fixed-price artifact that captures how your business sounds and makes it enforceable. No style drift. No copy that reads like a machine wrote it. Just your voice, kept yours.

If the copy your AI tools produce keeps sounding generic or off-brand, this is how you make it sound like you again, and keep it that way.
