BrandVoice · by Adytum

Every piece of copy on your site, in your brand voice — without rewriting.

Drop a snippet onto your site. Define your voice in 5 questions. Get rewriting in operator-grade AI that actually sounds like you — not like ChatGPT's default voice.

Try the free rewrite → Set up your saved voice

Six brand-voice characters, each one a persona the AI inhabits. Or extract your own voice from your site's URL in 6 seconds.

Live demo

Paste any rough copy. Get it rewritten in a chosen brand voice.

Pick a voice profile below, paste copy in the left panel, click Rewrite. The right panel returns the same content in that voice. Standalone — runs in your browser, no signup needed.

→ Output appears here after you click Rewrite.

How it works

Five questions. One snippet. Done.

Set up takes under 4 minutes. Drop the snippet anywhere you write — your CMS admin, your email tool, your blog editor.

Step 01

Answer 5 voice questions

Two example sentences you wrote. Three brands you admire. Three "we never say this" examples. Done.

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 → AI rewrites in your voice. Iterate 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 specific voice profile (built from your real writing examples + the brands you admire + the patterns you avoid) into every request. Same model, different — and consistent — output. The other difference: BrandVoice is one click inside your existing workflow, not a separate tab to context-switch into.

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 — 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 — 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?

You hit "Refine" — tell BrandVoice what was off (too formal, too long, lost the specific phrase, etc.). The profile updates. Next rewrite lands closer. After 20-30 uses, your profile is sharp enough that 80%+ outputs are usable 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.
