// brand · voice diff

Do you sound like your competitor?

Two URLs in. Both pages get a measured voice profile (rhythm, formality, perspective, energy, vocabulary), then a side-by-side diff and a differentiation score. If your copy could be swapped with theirs and nobody would notice, that's not a style choice, it's a positioning problem.

$Dimension by dimension

Five measured dimensions per site. Matching values are flagged: a match is only good news if you're the market leader.

$Vocabulary overlap

Signature words each site repeats. Shared words are the category talking; unique words are a voice you can own.

Frequently asked questions

What does Voice Diff do?
Put in two URLs and it measures each site's voice profile side by side, shows the vocabulary they share, and gives a differentiation score.
Why compare your voice to a competitor's?
If you sound like the whole category, an AI describing the category has no reason to single you out. A higher differentiation score means you read as distinct.
Is it free?
Yes, free and no signup. It reads both pages once.
