ClearScript finds the stiff parts and helps you clean them up fast

How it works

Three steps, under 30 seconds

1

Paste your text

Paste text directly or upload a PDF, Word, or TXT file. Check up to 30,000 words in one scan if the plan allows it

2

Run the scan

Click Detect AI and get results in seconds. ClearScript checks output patterns from ChatGPT, GPT-5, Claude, Gemini, DeepSeek, and more

3

See the report and fix what was flagged

Review sentence-level results, rewrite highlighted parts with the AI Humanizer, then rescan to confirm the draft looks right

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

Humanizer

Sentence level report

See the exact lines that triggered the score, not just a vague percentage

Report

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.
