Lettera

A quiet plain-text writing space.

Lettera is a cross-platform desktop app for writing plain text without distractions. Inspired by the Olivetti Lettera typewriter.

Open a window, start writing, and come back later. That's it. No markdown preview, no folders, no databases — just you and the text.

Philosophy

• Immediate writing. No setup, no classification, no friction.
• Plain .txt files. Your words live in regular text files you can open anywhere.
• Auto-save. You write, Lettera saves. No ⌘S anxiety.
• Zen UI. The editor is the center. Everything else fades away.
• Small and focused. Lettera resists feature creep by design. See DESIGN.md.

Status

🚧 Pre-release / Phase 3 complete. The writing surface, local persistence, and temporary Document selector are implemented; preferences and later product work remain future scope. See CHANGELOG.md.

Tech stack

• Rust — native binary, robust filesystem logic.
• Floem — reactive, cross-platform native UI toolkit. Lettera builds its editor on Floem's TextEditor.

No Electron. No webview. No browser.

Getting started

Coming soon. The project is in early development.
