BUSINESS 2 · VALIDATING DEMAND
Stuck on an
EPUB rejection?
We are researching whether authors need help interpreting and repairing a small, reproducible EPUB validation failure. This service is not yet available for purchase.
Start with the free validator
W3C EPUBCheck checks EPUB conformance. Run it locally before paying anyone for validation. Passing a validator is not a guarantee of retailer acceptance or a complete accessibility review.
The proposed service
A proposed $39 fixed-scope pilot would explain one reproducible structural validation issue, provide a corrected synthetic example or minimal authorized patch, and document how to recheck it. It would not rewrite your book, certify accessibility, guarantee sales, or guarantee retailer acceptance. Price and feasibility are being tested; no payments are collected here.
Three questions for authors
- Which exporter and distribution platform are involved?
- What exact error code or sanitized error text blocks you, and what have you tried?
- Would a scoped $39 repair be useful, or does a free explanation solve it?
Share your experience by email
No manuscript uploads, purchases or commitments. Do not send unpublished book text, personal data or account credentials. We may use authorized OpenAI tools to review sanitized technical feedback. Participation does not subscribe you to marketing.
We will only build the service if independent authors provide concrete unresolved examples and meaningful willingness to pay. The existing Playwright diagnostic pilot continues separately.
