Letters

Alpha

A pure Rust, minimalist word processor for the GNOME desktop — DOCX, ODT, Markdown, and PDF.

Letters is a clean, focused word processor for GNOME, written in Rust with GTK4 — no WebKit, no Python. It reads and writes DOCX natively via rdocx, ODT, and Markdown via pulldown-cmark, with footnotes and CommonMark round-trip fidelity. Shares the suite-common scaffold with Tables and Decks.
