Action word density
Measure narrative pacing by how many action verbs appear in each segment of your text.
Action word density
Action word density measures how fast a passage feels by counting action and motion verbs — ran, grabbed, struck, leapt, slammed and their -s/-ed/-ing forms — in each segment of the text. A high-density segment reads as fast-paced action; a low one reads as slower description, dialogue or exposition. It is a common revision technique for fiction, screenwriting and copywriting: if every scene comes out at roughly the same density, the pacing may feel flat even when the plot itself is moving.
Split the text either by paragraph, the default, or into fixed-size chunks of a chosen number of words, useful for pieces without clear paragraph breaks. Each segment reports its word count, action words, density as a percentage, average sentence length, and a small block bar so the pacing curve across the document is visible at a glance in plain text. Two extra counters flag likely pacing signals: short sentences, a proxy for quick, punchy pacing, and passive-voice markers such as "was slammed" or "has been running", which tend to slow a passage down even when the underlying verb is an active one.
The built-in list covers dozens of common English action verbs with their everyday inflections. Add genre slang, character-specific verbs or anything else the list misses as a comma-separated list of your own, and they are folded into the count using the same basic -s/-ed/-ing endings. Sort the segment list by density to jump straight to the fastest or slowest part of the text, or keep it in document order to read the pacing curve the way it actually unfolds on the page.
