Worth saying plainly

What a detector score is, and what it is not.

Detectors measure how predictable writing is. Predictable writing is common in machine drafts, and it is also common in careful, plain, technical, and non-native English. That overlap is the whole problem with the category, and it does not go away because a number looks confident.

  1. 01

    It is a likelihood, not a finding

    A high score says the writing is predictable. It does not say a model wrote it, and no detector can tell you that.

  2. 02

    Human writing gets flagged

    False positives are routine, and they fall hardest on writers whose prose is plain or who are writing in a second language. Never use a score on its own to accuse anyone of anything.

  3. 03

    Detectors disagree with each other

    Vendors retrain without notice and publish no contract. Two tools will score the same paragraph differently, so a score here does not predict a score elsewhere.

  4. 04

    We name the one we use

    This page reports one reading from one provider. Sites that animate a row of competitor logos while calling a single API are showing you a decoration.

After the score

A high score is a cadence problem.

What detectors pick up on is what makes machine prose tiring to read: sentences that are all the same length, openings that are all the same shape, and the expected word every time. Fixing that is ordinary editing, and it is worth doing whether or not anyone is scoring you.

01

Vary the sentence length

The single strongest signal, and the one a reader notices first. Mixing short, middle, and long sentences changes both the score and the reading experience.

02

Rewrite, do not swap synonyms

Detectors are trained on paraphrased output. Replacing words leaves the rhythm intact, which is the part being measured.

03

Keep every fact

The humanizer rewrites cadence and nothing else. Figures, quotes, names, links, and formatting come through exactly as written.
