Question 1

Does Manucheck guarantee my book will be approved by Amazon KDP?

Accepted Answer

No. Manucheck provides AI-powered publishing guidance only. It highlights issues that commonly cause problems and gives you a readiness score, but Amazon makes its own decisions and this platform is not affiliated with Amazon.

Question 2

Why do I need my own OpenAI API key?

Accepted Answer

Bring-your-own-key means your manuscript is processed under your own OpenAI account and usage terms, with no shared model pool and no per-word markup from us. You keep control, and your subscription pays for the platform rather than resold tokens.

Question 3

How is my API key stored?

Accepted Answer

The key is encrypted server-side with AES-256-GCM using a key held in secret storage, never written to logs, and never returned to the browser. The interface only ever shows the last four characters.

Question 4

What happens to my manuscript after analysis?

Accepted Answer

Every uploaded manuscript expires seven days after upload. On day 5 you get a reminder notification, and on day 7 the original file, the extracted text and any processing cache are permanently deleted. Your generated reports are retained in your dashboard.

Question 5

Which file formats are supported?

Accepted Answer

DOCX, PDF, EPUB and TXT. Free accounts can upload files up to 100MB; paid plans up to 200MB.

Question 6

Can I use Manucheck for fiction and non-fiction?

Accepted Answer

Yes. The analysis engine adapts its structural expectations to the manuscript type, so a novel is not judged against a business book's front-matter conventions.

Question 7

Do you train models on my book?

Accepted Answer

No. Your manuscript is sent only to OpenAI under your own API key for the purpose of generating your report, and is deleted from our storage within seven days.

Question 8

Can I cancel at any time?

Accepted Answer

Yes. Subscriptions are monthly and can be upgraded, downgraded or cancelled from the Billing page. Access continues until the end of the paid period.

Question 9

How does the copyright and trademark review work?

Accepted Answer

The engine flags passages that reference brands, quote external work, or reuse recognisable material, and explains why each one may need attention. It is a prompt for human review, not a legal opinion.

Question 10

Do you support teams?

Accepted Answer

Pro includes team access so editors and production staff can review reports alongside the author, plus API access for studios that want analysis inside their own pipeline.
