The Humanization Score is the measurable benchmark on every TextSight output. Higher means more human-like. Lower means more AI fingerprints. Same number on every scan and every rewrite — so you always know exactly how far the draft is from where you want it.

Most AI detectors give you a single percentage — "78% AI" — and walk away. That number tells you the verdict, but not the gap. You don't know whether you're close to ready or three rewrites away.
The Humanization Score is the inverse benchmark. Same 0-100 scale, but it measures how natural the text reads — so 35 is "definitely AI-flavored," 60 is "borderline," 75+ is "passes most reader scrutiny," and 85+ is "indistinguishable from a careful human author."
Every TextSight scan shows it. Every Humanizer rewrite recomputes it. The score climbs as you rewrite — so you can stop guessing and start measuring.
Most readers and detectors will flag it. Don't ship.
Some detectors flag, some don't. Run another rewrite pass.
Good for personal writing and most blog content.
Target for academic submissions and editorial content.
Hard to distinguish from a careful human author. Target for compliance, legal, journalism.
The Humanization Score is a weighted blend of several language signals — none of them new individually, but combined into a single number you can act on:
Each signal contributes a weighted component to the final 0-100. Weights are tuned against a benchmark of human-vs-AI-authored content. The score is probabilistic — like every AI detection signal — so we publish the methodology, the benchmark setup, and the caveats openly.
Every scan returns the Humanization Score alongside the AI probability and sentence highlights.
After each rewrite, the score is recomputed so you can see your progress in real time.
Every paraphrased output shows the score so you can decide which variant to keep.
Summaries are scored, so you can tell when a TL;DR is too obviously AI-styled.
Edits that "fix" grammar but make the text more AI-flavored are flagged by a score drop.
Every writing tool in /tools/ returns a Humanization Score inline with its output.
It's not a third-party detector pass guarantee. The score is computed against TextSight's own detector. A high score correlates with passing most other detectors, but no single number guarantees a pass on Turnitin, Originality, GPTZero, or any specific tool. If you need to pass a specific detector, verify by re-scanning on that tool.
It's not infallible. Like every AI detection signal, the score is probabilistic. Heavily edited AI text can score high; deliberately stilted human writing can score low. We flag low-confidence scores on short or unusual text.
It's not a quality score. Humanization is one dimension of text quality — not the whole picture. Well-organized, factually accurate, persuasive writing can score lower than rambling prose. Pair the Humanization Score with the Readability Checker and the Fact-Checker for a fuller view.
A 0-100 measurement of how natural and human-like a piece of text reads. Computed by TextSight on every AI Detector scan and every AI Humanizer rewrite. Higher means more human-like; lower means more AI fingerprints.
A weighted blend of burstiness, perplexity, lexical diversity, structural patterns, and model-specific fingerprints. Weights tuned against a benchmark of human-vs-AI content. Read the full methodology.
Depends on the stakes. 60+ for personal writing, 75+ for academic submissions, 85+ for compliance / legal / journalism. Below 40, most readers and detectors will flag the text as AI-generated.
AI probability answers "how likely is this AI-generated?" (higher = more AI). Humanization Score answers "how natural does this read?" (higher = more human). Usually inversely correlated but not perfectly — a sentence can be obviously AI-written and still flow well, or vice versa.
No. The score is computed against TextSight's own detector. A high score correlates with passing most other detectors, but no number guarantees a pass on any specific third-party tool. If you need to pass a specific detector, verify by re-scanning on that tool.
Yes. Like every AI detection signal, it's probabilistic. Heavily edited AI text can score high; deliberately stilted human writing can score low. We flag low-confidence scores on short or unusual text. Use it as a benchmark, not a verdict.
Every AI Detector scan, every AI Humanizer rewrite, and every output from the 20+ free writing tools at /tools/. Anywhere TextSight processes text, you get the score.
