How does Tone of Voice Analysis work?

Analyze the emotional tone behind your words

Our tool breaks down your content and evaluates it using tone-specific language markers like sentence length, word choice, structure, and emotive language. It then maps your writing onto tone categories such as authoritative, approachable, professional, or quirky — similar to how readers emotionally interpret your message.

Get a tone profile with suggestions to realign your style

Once the analysis is complete, you’ll receive a tone breakdown along with suggestions to move your writing closer to your desired style. Want it more inspiring? More professional? More casual? We’ll guide you with concrete, sentence-level edits — making your tone consistent, clear, and on-brand.

Does this work in different languages?

Currently, it works best in English, but it supports most languages.
