🧪 Writing Content Writing Simulation

Interactive content-writing simulator: shape a 24-sentence article with sentence-length and word-complexity sliders, watch the Flesch-Kincaid readability score and a reader's page-by-page reading speed update live over a 3D difficulty terrain.

Every editor and SEO tool scores writing with the same pair of Flesch formulas: average sentence length and average syllables per word. This simulator turns those two numbers into a real 3D terrain built from a 24-sentence sample article — each bar's height and color is that sentence's own Flesch-Kincaid grade level — while a glowing reader sphere walks through the article at a modeled reading speed that slows down on the hardest sentences. Adjust sentence length, word complexity and sentence-to-sentence variety, or jump straight to a News / Academic / Ad-hook preset, and watch the Reading Ease score, grade level and estimated total read time update live.
