Document design and writing, rebuilt in pure Rust.
The word processor with the Microsoft Word workflow you already know: ribbon tabs, live styles, tables, track changes, and mail merge. Reads and writes .docx natively with zero Microsoft 365 subscription fees.
Engineered for Authors, Lawyers, and Teams
Real Word Compatibility
Open, edit and save standard Microsoft Word .docx files. Preserves typography, bullet styles, complex nested tables, and margin settings.
The Ribbon You Expect
Home, Insert, Layout, References, Review, and View tabs arranged identically to Word. Live Styles gallery lets you preview headings before applying.
Redlining & Comments
Professional editorial reviews: inline revisions, margin bubbles for author comments, and accept/reject tracking compatible with Office documents.
Instant 0.2s Startup
No splash screen delays, no cloud license checks, and zero background services. Type at 120 FPS even on 500-page academic manuscripts.
100% Offline & Private
No forced OneDrive sync or cloud telemetry scanning confidential legal briefs. Everything is processed strictly on your CPU and local NVMe drive.
MCP & CLI Automation
Every button is also an engine command. Drive WordCraft headlessly with Claude, Cursor, or python scripts over Model Context Protocol.
