Pre-Flight Reader Test

Pick the test that matches where the book is. Validate the listing before you write (Quick), or pressure-test the finished manuscript before you publish (Full). Upload once, and subsequent tests and downstream tools reuse the same parsed book.

Manuscript upload

Drop a .docx, .pdf, .epub, .txt, or .md. We'll auto-extract title, subtitle, blurb, chapters and word count. Quick mode only needs the first chapter, and uploading once means Full mode and other Wordhaven tools don't need re-uploading. Max 200MB.
