Tone of Voice Analyzer

The Tone of Voice Analyzer reads a piece of text and reports how it actually sounds — formality, emotion, urgency, and brand personality traits. Useful because the tone you intended and the tone on the page are often two different things. Free, no signup required.

Use it at storymint.id/tools.

How to use it

1. Paste the text.
2. Review the analysis across the tone dimensions.
3. Adjust and re-check until it sounds like you meant it to.

When to reach for it

• Checking consistency — does this guest post / agency draft / new writer sound like the rest of your content?
• Before a sensitive send — pricing changes, apologies, anything where a wrong register is expensive
• Diagnosing flat copy — copy that “reads fine but doesn’t land” often scores low on emotion and urgency

Going further with a campaign

Inside a campaign, this check becomes systematic: Brand Voice extracts your voice profile from your best content, every Content Writer draft follows it automatically, and each persona records its own preferred tone — so you can match copy to audience, not just to brand.
