The Last-Mile Solution

Review and Prepare Your EPUB in the Desktop Editor

Review the OCR result page by page, remove unwanted content, organize the table of contents, and choose your cover and reading styles before exporting.

Page-by-Page Review

Search the OCR text, jump to a source page, and review text, images, and formulas before choosing what to keep in your EPUB.

Noise Cleanup & Exclusion

Select unwanted text, images, content blocks, or whole pages to exclude from export. Undo deletions during the current editing session.

Custom TOC & Hierarchy

Promote or demote chapter headings (H1/H2/H3), search text to insert new table of content nodes, and keep your eBook organized.

Typography & Cover Controls

Select your preferred cover image, toggle Serif or Sans fonts, and fine-tune font size percentage and line height for e-readers.

Save a draft and return to your book

Save your draft, reopen it from History, and export again after adjusting content, navigation, or styles. Local editing and repeat exports do not use additional OCR credits.
