Partial The iOS app shell, EPUB packaging, metadata and TOC editing, and image optimization are vibe-codeable. Faithful PDF-to-reflowable-EPUB conversion, CBR/RAR extraction, and offline Chinese text conversion are harder.
What it would actually take: The stack is Swift/SwiftUI with an EPUB zip and XHTML/OPF generator, plus PDFKit for text extraction. Quality PDF reflow needs layout analysis (columns, headers, footers, and hyphenation), and Chinese conversion needs an OpenCC-style dictionary. Solid testing against many real-world EPUB and PDF files is also necessary.
