waai-Word: Create Edit Format

waai-Word is a fast, word processor with a familiar workflow: the ribbon, styles, tables, track changes, references and mail merge. Written entirely in Rust, it opens and saves .docx files, exports real PDFs, and works completely offline.

WHY WAAI-WORD

• Familiar — ribbon tabs, a live Styles gallery and shortcuts that behave the way you expect: Enter continues a list, Tab demotes it, ⌘B bolds the word under the caret, F4 repeats.
• Your files — .docx (read and write), plus .odt, .rtf, .html, .md, .tex and .txt; opens legacy .doc files; exports PDF with selectable text, links and bookmarks.
• Fast — paragraph layout is cached: typing in a 188-page document re-lays it out in about 1.4 ms. Pages render on demand. No Electron — native GPU rendering in a small footprint.
• Private — spelling, grammar and everything else work offline. Nothing leaves your Mac.
• Open — MIT OR Apache-2.0 licensed, clean-room built from public file-format specifications, with every asset original or openly licensed.
• Built for automation — every action is a command: the same 422 commands drive the ribbon, the keyboard, a command-line tool and a built-in MCP server, so AI agents can write and edit documents for you under your control.
