Technical writing lives or dies by whether a reader can follow it under pressure — installing a device, debugging an API, following a safety procedure. This simulator turns the qualities that make documentation clear or confusing into four real sliders (average sentence length, jargon density, passive-voice ratio, undefined acronyms) and recomputes a genuine Flesch Reading Ease score and Flesch-Kincaid grade level live from the resulting sample sentence's actual word and syllable counts. A 3D audience of 24 readers reacts in real time: as the document drifts from plain language toward dense jargon-heavy prose, more of them slump into visible confusion, giving an intuitive, quantified feel for exactly why style guides like the Microsoft Manual of Style cap sentence length and jargon in technical documents.
