How it works

This tool splits your text into individual sentences and counts the words in each one, then displays the results as a bar chart. This visual approach makes patterns in your writing immediately obvious.

• Rhythm & variation: good writing mixes short and long sentences. If the chart shows bars of similar height in a row, your prose may feel monotonous to readers.
• Variation score: the coefficient of variation (standard deviation divided by the mean, expressed as a percentage). Higher values indicate more sentence length diversity. Scores above 40% generally indicate strong variation.
• Color coding: bars are colored by word count — blue for short (1–8 words), green for medium (9–18), orange for long (19–30), and red for very long (31+). A healthy mix of colors suggests varied prose.
• Monotony detection: the tool flags runs of three or more consecutive sentences within the same length category, which can indicate repetitive rhythm.

All analysis runs entirely in your browser — nothing is sent to a server.
