About
De-AI-ify is a free writing tool that shows you the patterns making your prose feel mechanical, so you can fix them deliberately.
What it is
A deterministic, transparent writing-pattern analyser with a fix workflow. It parses your document once — paragraphs, sentences, words — and runs eleven independent detectors over the parsed result. Safe fixes apply in one click; judgement calls wait as smart suggestions you accept or dismiss individually; everything is undoable. Every finding explains itself and links back to the exact characters it refers to.
What it is not
It is not an AI detector, and it is not a service for evading AI detectors. There is no "AI probability", no "human score", and no claim that any output is "100% human". The Mechanical Writing Score measures patterns — repetition, rhythm, templated phrasing — that occur in human writing and machine-generated writing alike.
How it is built
De-AI-ify is a statically generated site with no backend. The analysis engine is framework-independent TypeScript, runs inside a Web Worker so long documents never freeze the interface, and is covered by unit tests covering parsing, offsets and each detector. Sentence and word segmentation use the platform's Intl.Segmenter where available, with a conservative fallback.
Reading the results
Treat the score the way you would treat a spell-checker underline: as a prompt to look, not a verdict. Some findings will be noise for your genre; some will be exactly the thing you were sensing but could not name. The methodology page documents every threshold.
