What it checks
Six review passes over your manuscript, in one run
Each pass is scored independently so you know exactly which part of the book needs work — the prose, the file, or the listing.
AI Manuscript Review
A full read of your book, not a spell-check. Manucheck evaluates writing quality, structure, organization, readability and grammar chapter by chapter.
- Writing quality

- Organization
- Readability
- Grammar
Publishing Readiness Review
Catches the mechanical problems that get manuscripts bounced or rebuilt after upload: layout, matter and chapter architecture.
- Formatting
- Front matter
- Back matter
- Chapter structure
- Book organization
Metadata Assistance
Discoverability is decided before the first reader arrives. Get concrete metadata your listing can use on day one.
- Title
- Subtitle
- Keywords
- Categories
- Book description
Quality Improvement
Pinpoints the passages that lose readers, with specific rewrites instead of vague encouragement.

How it works
From upload to actionable report in minutes
Connect your OpenAI key
Manucheck runs on your own OpenAI API key. It is encrypted with AES-256-GCM before storage and never displayed again after you save it.
Upload your manuscript
Drag and drop DOCX, PDF, EPUB or TXT. We validate the file, show upload progress and store it in an encrypted private bucket.
Text extraction
The document is parsed into clean text. Formatting signals — chapter headings, front matter, back matter — are preserved for the structural pass.
Multi-pass AI analysis
Writing, publishing readiness, metadata and risk are reviewed against the current KDP guidance ruleset, stamped with its policy version.
Report generation
You get scores per category, ranked issues, concrete recommendations and a pre-publication checklist you can print or export to PDF.
Automatic deletion
On day 5 we remind you. On day 7 the original file, extracted text and processing cache are permanently deleted. The report stays.
Privacy by design
Your book leaves in seven days. Always.
Manuscripts are stored in a private encrypted bucket only your account can read. On day five you get a reminder. On day seven the original file, the extracted text and every processing artefact are permanently deleted. Your reports stay.
Analysis runs on your own OpenAI API key, encrypted with AES-256-GCM and never shown again after you save it. Your manuscript is never used to train a model.
Encrypted at rest
AES-256 storage and AES-256-GCM key envelopes.
7-day expiry
Enforced by schedule, not by request.
Row-level security
Access enforced in the database itself.
Audit logging
Append-only record of privileged actions.
What authors and publishers say
“I had three rounds of formatting problems on my last release. Manucheck found every one of them in eleven minutes, before I uploaded anything.”
“We run twenty-two titles a year. The readiness checklist replaced a two-page internal doc that nobody kept current.”
“The metadata pass alone paid for the year. Our keyword set was lazy and the category recommendations were sharper than what we had been guessing at.”
“The trademark flags caught two brand references I would have shipped without thinking. That is exactly the kind of thing you want a second reader for.”
