Description
WordCraft Online is a free open-source word processor written in Rust that runs in the browser. It provides the familiar ribbon, styles, tables, track changes and references. It opens and saves Microsoft Word .docx files along with ODT, RTF, HTML, Markdown and plain text. Documents never leave the device because everything runs locally with WebAssembly. No account is needed for the editor. The web build is the official unmodified release from the ArtCraft team under MIT or Apache-2.0. An optional AI writing assistant is available with the user's own key or credits.
