How ClearScript AI detection works

Most detectors catch raw AI output. ClearScript looks at the full draft for sentence rhythm, predictable phrasing, repeated structure, and edited AI patterns that survive after a rewriter or grammar tool has touched the text.

ClearScript benchmark: 99.8% accuracy across internal writing samples
01

Signal analysis

We scan word choice, sentence rhythm, and structural repetition across the full document

02

Context check

We compare each line against the surrounding draft so formal, edited, or non-native writing gets better context

03

Confidence report

You get a score, sentence highlights, and a clear next step for what needs a rewrite

Why ClearScript?

One click to sound human

Spotted AI sounding text? Rewrite it in a more natural voice without starting over

Built for edited AI drafts

The launch memo reads clearly, but several lines use the same polished rhythm.

Each sentence starts with a broad claim before moving into generic support.

The core idea is strong and the examples are specific enough to keep.

A quick rewrite would make the draft sound less templated.
