Check ebook coherence and facts before publishing

Chapter quality is not book quality

Ten individually readable chapters can still make a poor book if they repeat the same lesson, contradict each other, change terminology, or introduce prerequisites after they are needed. Pro-quality projects can use coherence-oriented review across the manuscript rather than judging each chapter in isolation.

Fact checking still needs judgment

Automated factual review can identify and correct many risky claims, but it should not be treated as a guarantee. Before publication, manually inspect claims with legal, medical, financial, scientific, reputational, or rapidly changing consequences.

• Check numbers and dates against the underlying source.
• Keep opinion and evidence clearly separated.
• Verify named people, companies, studies, and quoted claims.
• Re-check facts that were current when the source was collected but may have changed since.

Fact checking and plagiarism checking are different systems

Pro fact checking is part of the generation pipeline: it compares factual claims against source excerpts available to the chapter and can run an automatic correction pass when problems are found.

The plagiarism scan is a separate review/publishing tool. It measures similarity against the project's internal source material and, when the web check is available, external web matches. Its result can be Original, Checked, or Needs review; it does not certify factual truth.

Know the limit of source-grounded fact checking

The automated fact-check step only has evidence when source excerpts are available. A claim outside that evidence can still require manual verification even when the Pro pipeline completed successfully.
