How it works

Five questions. One snippet. Done.

Setup takes under 4 minutes. Add the snippet anywhere you write, such as your CMS admin, email tool, or blog editor.

Step 01

Answer 5 voice questions

Give two example sentences you wrote, three brands you admire, and three "we never say this" examples.

Step 02

Drop the snippet

One script tag. Adds a "Rewrite in brand voice" button to every text input on your site.

Step 03

Rewrite anywhere you write

Product descriptions, email subject lines, landing pages, social. Click and the AI rewrites it in your voice. Repeat until it's right.

Step 04

Voice evolves with use

Every time you accept or edit an output, BrandVoice learns. Your voice profile sharpens automatically.

FAQ

The honest answers.

How is this different from just using ChatGPT?

ChatGPT defaults to a single neutral voice. BrandVoice loads your voice profile (built from your real writing examples, the brands you admire, and the patterns you avoid) into every request, so the same model gives different, consistent output. BrandVoice is also one click inside your existing workflow, so you don't switch to a separate tab.

Does it work with Shopify / Squarespace / Wix?

Yes. The snippet works on any platform that lets you add a script tag. That's Shopify (Theme Editor), Squarespace (Code Injection), Wix (Custom Code), Webflow (Custom Code), WordPress, plus any custom site. We also have a dedicated Shopify App in review.

What model does it use?

Claude Sonnet by default, for the best balance of voice fidelity and cost. Studio tier gets Claude Opus for highest-stakes work. We test new models monthly and swap in if they improve voice quality.

Does my data get used to train AI?

No. The free demo runs entirely in your browser, and your text never leaves your device. Paid tiers (Pro / Scale) use a private inference path with no training on customer data, deletable any time from your dashboard.

What if the rewrites aren't on voice?

Hit "Refine" and tell BrandVoice what was off (too formal, too long, lost the specific phrase, etc.). The profile updates and the next rewrite lands closer. After 20-30 uses, 80%+ of outputs are usable on the first try.

Can I cancel?

Any time, in your dashboard. No reactivation fee if you come back. Annual plans are pro-rated refund if you cancel before the year's up.
