Which passages read as machine-written?

AI detectors are unreliable in both directions and prove nothing. This advisory check reads the whole manuscript in parts, flags exact passages that may sound generic or machine-like, and explains why. It cannot prove authorship, measure actual AI use or determine disclosure requirements.

What it does, precisely

  • Reads the current whole manuscript in parts and gives an advisory style score
  • Flags exact passages that read generic or machine-like and explains the signal it noticed
  • Helps you find flattened voice, even rhythms and abstract language worth reviewing
  • Keeps the result with the book so you can revisit the flagged passages

Try a separate free writing review

A separate writing review for clarity and reader impact; it does not check AI use, prove authorship or decide disclosure. Send up to 5,000 words. You get back what the draft appears to be doing to somebody who wasn't there when you wrote it, the strongest thing in it named, the exact place a reader starts to drift, and three revision priorities in order.

Or see how it works first

A separate writing review for clarity and reader impact; it does not check AI use, prove authorship or decide disclosure. An AI-assisted read of your own pages. Not a human edit, not a line edit, and not a scored report.

What it does

The check sends the current whole manuscript to a stylistic-perception model in manageable parts. It looks for patterns an experienced editor may associate with machine-written prose, then combines the part results into an advisory score and a list of exact passages. It does not compare your draft with suggestion history or an authorship ledger.

However you write

It assesses the words currently in the manuscript. It cannot know who wrote them, how much AI was actually used, or whether a publisher or retailer requires disclosure.

The mistake: treating a style estimate as proof

No automated detector can prove who wrote a book or calculate how much was generated by AI. A low score is not evidence of authorship and a high score is not evidence of misconduct. Use the flagged passages as editorial prompts, then answer each platform’s disclosure question from what actually happened in your writing process.

About Your Book Pro

Your Book Pro is a book-writing platform built in Britain. Start with an idea, notes, half a draft, a podcast, or a finished manuscript, and use our purpose-built AI tools for planning, feedback, editing, proofreading, cover designs, and to create print-ready files. Writing is totally free: you can type, upload or speak your book as much as you like, and use only the editing tools you need with Plus, or go unlimited with Pro.

Produce world-class drafts at the fraction of the cost of hiring a human editorial team.

Every account starts with 1,000 welcome credits, and a plain export of your own words is free.

One rule shapes all of it. Your words are stored as Exact Text and are never overwritten. Every suggestion arrives attached to a place in your manuscript, and nothing changes until you accept it. Where most AI tools quietly rewrite you into their own register, this one shows you the change and waits. Even the automatic clean-up pass is held to a length check — if it drifts too far from what you actually wrote, the edit is thrown away and you keep your own words. The editorial standards behind the feedback are our own, written for books and specific to your genre, not a general chatbot answering in a good mood.

The Footprint Checker reads the current manuscript and looks for stylistic patterns that an editor or reader may perceive as machine-like. It returns an advisory score and exact passages to review; it does not compare drafts or maintain a provenance ledger.

This is an advisory stylistic assessment. It cannot prove authorship, actual AI use or disclosure obligations.

Where it stops

This is an advisory stylistic assessment, not proof. It cannot determine authorship, calculate the amount actually generated by AI, or decide whether disclosure is required.

Where to find it

The AI Footprint check runs from the readiness checklist on the Prepare tab and saves its result to the book. Ask the Editor can also launch it and discuss the saved report.
