Hammer

Hammer is a cross-platform story writing application designed to help authors create and manage fictional projects without depending on cloud services. It provides a dedicated environment for developing stories on phones, tablets, laptops, and desktop computers. Its adaptive interface accommodates different screen sizes and supports light and dark themes. Projects are stored locally using human-readable files and folders instead of proprietary databases. Writers can access their work offline without requiring an internet connection. Optional synchronization keeps projects consistent across devices while reducing the risk of conflicting changes. Users can host their own synchronization server or use the official service. Hammer supports Android, iOS, Windows, macOS, and Linux.
