Brand tone analyzer — score your copy in seconds
Paste any piece of writing and this tool scores its tone of voice across three dimensions — formality, warmth and confidence — alongside basic readability stats. It then gives you concrete suggestions to pull the copy toward the brand voice you actually want. Everything runs in your browser, so you can check sensitive draft copy without sending it anywhere.
How it works
Tone is hard to judge by feel, so the analyzer turns it into measurable signals. It scans your text for vocabulary associated with each end of three axes:
- Formality — casual words and contractions versus formal connectives like “therefore” and “accordingly”.
- Warmth — reader-focused, emotive language versus cold, policy-style wording.
- Confidence — direct claims versus hedging words like “maybe” and “I think”.
Each axis is scored from 0 to 100 based on the balance of those signals, and the result is shown as a slider so you can see at a glance where the copy sits. Sentence length and punctuation are measured separately as readability cues — long average sentences are flagged because they reduce clarity regardless of tone.
Tips and examples
Run the same paragraph against two different target profiles to see how the suggestions change — “friendly” will push you to add warmth, while “authoritative” rewards confident, direct phrasing. If a draft scores very high on confidence, check for overpromising absolutes like “always” or “guarantee”. If warmth is low in a customer email, adding a single “thanks” or “happy to help” usually lifts it noticeably. Use the readability line as a final pass: aim for an average sentence length under about 20 words for marketing copy.
