Write a book in chapters and export a properly typeset EPUB and PDF.
A free browser writing environment aimed at novelists: chapter structure, word goals, collaboration with an editor, and — the part that matters — a one-click export that produces a genuinely well-typeset EPUB and print-ready PDF rather than a Word file with a new extension. It is free because Reedsy is a marketplace for editors and cover designers. It is not a general word processor.
Questions
Free to use, but you have to register before it will do the job. Built for books only, and the export templates are a small fixed set you cannot restyle.
Yes. Reedsy Studio sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
