The "Tone Gap" is costing you.

When Sales sounds aggressive, Support sounds passive, and Marketing sounds like a meme, your customer loses trust. BrandVoice unifies the narrative.

Frequently Asked Questions

How is this different from ChatGPT?

ChatGPT is a generalist. BrandVoice is a specialist trained specifically on your data. We don't just generate text; we enforce strict stylistic, terminological, and tonal rules that generic models ignore.

Is my data used to train other models?

Never. We are SOC2 Type II compliant. Your data is isolated in your own container and is deleted from our training cache immediately after model generation.

Can I invite my freelance writers?

Yes! You can invite external guests with limited permissions. They can use the tools to write content for you, but they cannot change your core voice settings.
