How it works

1

Rewrite

Text is chunked and rewritten by an LLM with a prompt tuned to inject human writing patterns — varied rhythm, imperfect transitions, mixed register. Code blocks pass through untouched.

2

Verify

Output is checked against AI detectors. Flagged sections are identified at sentence level so rewrites are surgical, not sledgehammer.

3

Iterate

Flagged sentences get targeted rewrites. Loop runs until detection passes or max retries. You get the final score.
