How this tone checker works
Different audiences expect different writing styles. A landing page that reads like a research paper will lose casual readers, while marketing copy that reads like a tweet can feel out of place in technical documentation. This tool compares your text's readability grade level, average sentence length, passive voice percentage, and adverb usage against typical ranges for four common audience profiles, then gives you a single fit score from 0-100.
Audience profile targets
| Audience | Readability grade | Passive voice | Avg sentence length |
|---|---|---|---|
| Casual | 5-9 | Low (<10%) | Short-medium (8-18 words) |
| Marketing | 5-9 | Very low (<8%) | Short, punchy (6-15 words) |
| Technical | 9-14 | Moderate OK (<25%) | Medium-long (12-25 words) |
| Academic | 11-17 | Higher OK (<35%) | Longer (15-28 words) |
These are general guidelines, not hard rules. Strong writing for any audience still benefits from clarity and varied sentence rhythm. Use the checklist below to see exactly which dimensions are pulling your score down.
