Paste at least 50 words of writing for analysis. 300 or more words produces the most reliable results.
What This Tool Measures
Most writing advice is subjective: "be clear," "find our voice," "vary our sentences." This tool replaces vague guidance with numbers. It analyzes five dimensions of writing style drawn from stylometry research:
- Sentence Architecture measures length, variety, and complexity mix (simple, compound, complex). A 14-word average reads differently from a 28-word average.
- Vocabulary Profile measures lexical density (content words vs. function words), sophistication (common vs. uncommon vocabulary), and contraction frequency.
- Rhythm and Pacing maps paragraph length and punctuation habits: em dashes, semicolons, colons, parentheticals. These patterns create the feel of writing without most readers noticing.
- Readability calculates Flesch-Kincaid grade level and reading ease, with the word and syllable breakdowns behind the score.
- Voice and Stance profiles pronoun usage (first person, second person, third person), hedging language vs. certainty markers, and overall formality.
How to Use the Results
Paste 500 to 1,500 words from a single piece of writing. The tool works best on finished or near-finished prose rather than notes or outlines. To map consistent patterns, run the analyzer on 3 to 5 different pieces and look for what stays the same across samples. Those consistent patterns are the measurable core of a writing voice.
The results pair well with our style specification guide, which shows how to turn these numbers into instructions for AI writing tools.
