What oStorybook is
oStorybook is free, open-source desktop software for writers, essayists, and authors who want to organize a story as it develops from draft to finished work. It keeps characters, locations, scenes, objects, reference points, and ideas within one project. Writers can switch among chronological, chapters-and-scenes, book, and reading views to work with the story in different ways. Scenes can be associated with a main story thread and, optionally, secondary threads. A Global Ideas feature lets authors record ideas and track whether each is not started, started, finished, or abandoned.
Writing tools include text spell-checking with a customizable dictionary and synonym and antonym lookup. Projects can be imported from LibreOffice ODT and Microsoft Word DOCX, and exported to ODT, DOCX, TXT, CSV, HTML, XML, or SQL. The desktop application supports Windows, macOS, and Linux. Download packages are listed for Debian Linux, Red Hat Linux, Windows, and Mac OS X, with a ZIP for other systems. Java 8 or OpenJDK is required. Users can run the software without registering; an account is needed to post a question on the help forum. The help forum may not always work, and the team can also be contacted by email. The listed free plan costs nothing.
