Detect the footprint
AI leaves in your writing
CleanOutput scans essays, emails, articles, and any prose for AI signatures — and shows you exactly how to fix them, word by word.
Three steps to cleaner writing
Paste your text
Drop in any AI-assisted writing — essays, emails, articles, reports. No word limit, no account needed.
Scan for signatures
Our engine checks 9 linguistic dimensions instantly — vocabulary, cadence, passivity, redundancy, and more.
Fix and export
See color-coded highlights, hover for alternatives, or click Auto-Clean to rephrase predictable patterns in one click.
What CleanOutput detects
Every metric is calibrated against thousands of AI-generated samples to give you a reliable, objective score.
AI Vocabulary
200+ high-frequency "lexical leak" words that AI overuses — from "delve" to "tapestry" to "leverage."
Passive Voice
AI leans heavily on passive constructions. We flag them all with suggested active rewrites.
Burstiness (Cadence)
Humans write with rhythm variation. AI outputs sentences of eerily uniform length — we measure the standard deviation.
Hedging Language
"It's worth noting," "one might argue" — AI over-qualifies. We flag and help you cut the fat.
Readability Score
Flesch-Kincaid analysis reveals unnaturally consistent grade-level — a hallmark of AI calibration.
Structural Uniformity
AI loves perfectly balanced paragraphs. We measure paragraph-length variance to catch robotic layout.

Common questions
No AI detector is 100% accurate — including ours. CleanOutput gives you a probabilistic score based on nine measurable linguistic signals. Think of it as a quality audit rather than a verdict. Use the score and highlights as a guide, not a judge.
Never. CleanOutput runs entirely in your browser using JavaScript. Your text is never sent to any server. Once you close the tab, it's gone.
CleanOutput is optimized for formal prose — essays, articles, blog posts, professional emails, and reports. It works less well on highly technical content, code, or creative fiction with very unusual style choices.
