Features

CodeMirror 6 Editor

Markdown editing with syntax highlighting, live preview, and synchronized scrolling between editor and preview panes.

Style Check

Aho-Corasick pattern matching in Rust. Flags filler words, redundancies, and clichés as you type. Add your own rules.

Folder Workspaces

Point Writer at any directory. Full file operations with drag-and-drop, context menus, and automatic filesystem watching.

Quick Capture

Global hotkey opens a capture window from anywhere. Create timestamped notes or append to existing documents.

Focus Mode

Typewriter scrolling, paragraph dimming, and minimal chrome. The interface fades so the text doesn't.

Export

PDF, DOCX, and plaintext. Configurable page layout, fonts, and an inline preview before you commit to a file.

Local-First

Your documents stay on your machine as plain markdown files. No cloud sync required, no vendor lock-in. Writer uses your existing folder structure as the source of truth.

Built on Tauri 2 with a Rust backend handling file operations, indexing, and NLP. The frontend is React 19 and CodeMirror 6.

Writing Assistance

Style checking runs in real-time, highlighting potential issues without being intrusive. Pattern matching happens in Rust via Aho-Corasick for consistent performance.

Parts-of-speech highlighting shows sentence structure at a glance. Customize patterns to enforce a house style guide.

Quick Capture

Set a global hotkey and capture ideas from anywhere on your system without switching windows. Three modes: quick note, append to document, or start a writing session.

Notes land in your inbox folder, ready to be triaged later.
