What it does
Book Studio for the web is the browser version of the Book Studio plugin. Open a folder of Markdown notes, or write and import a manuscript (.md, .txt or Word .docx), and export a print-ready PDF interior for Amazon KDP and an EPUB 3 that passes EPUBCheck.
Everything runs in your browser. Nothing is uploaded, and there is no account, no cookies and no analytics. It is free and open source.
