What the analyzer measures

Four lenses on one draft. Structure: words, sentences, and the words-per-sentence average that drives rhythm. Readability: the Flesch Reading Ease score and Flesch–Kincaid grade, computed with the standard formulas and translated into a plain-English band. Vocabulary: unique-word count and your top keywords by density, stop-words excluded. Delivery: reading time at the published 238 wpm average and speaking time at presentation pace. Formulas and conventions are documented on the methodology page.

Focused tools, deeper guides

Each analysis also has a dedicated page: the Readability Checker for score-by-score interpretation, the Keyword Density Checker for the SEO view, the Word Frequency Counter for hunting overused words, and the Speaking Time Calculator for talks, videos, and ad reads.

Analysis happens locally in your browser — nothing you paste is transmitted or stored. See the methodology page.
