What You Can Do

You can automatically audit your e-book manuscript against industry production standards, identifying formatting errors, metadata gaps, accessibility violations, and consistency issues in minutes. The validator analyzes your content structure, validates technical requirements, and generates a prioritized report of fixes needed before publication.

Features

Formatting validation

Checks typography consistency, paragraph spacing, indentation, heading hierarchy, and style application across your entire manuscript.

Metadata verification

Validates ISBN, author/editor information, publication date, language tags, and cover metadata against publishing standards.

Accessibility audit

Ensures WCAG 2.1 compliance for screen readers, verifies alt text for images, checks color contrast, and validates semantic structure.

Link and reference validation

Tests internal cross-references, table of contents accuracy, footnote links, and external URLs for functionality and correctness.

Spelling and grammar scan

Identifies typos, punctuation errors, repeated words, and common grammar mistakes that automated spell-checkers might miss.

Cover specification check

Validates cover dimensions, bleed areas, file format, color profile (CMYK/RGB), and resolution against platform-specific requirements.

Image quality assessment

Checks image resolution, aspect ratio compatibility, file size optimization, and embedding standards for different e-reader formats.

Production-ready report

Generates a detailed, categorized report with severity levels, specific locations of issues, and actionable recommendations for remediation.
