Write

A distraction-free writing app that silently fixes your spelling as you type.

---

Write is a standalone writing application built in Rust. It opens its own window — double-click the exe, start writing. An LLM runs in the background to fix typos and spelling mistakes using surrounding context, so you never break flow. Documents save as .md files.

The interface uses a warm Taliesin color scheme inspired by Frank Lloyd Wright's prairie aesthetic: parchment backgrounds, walnut text, terracotta and gold accents.

Features

• Context-aware proofreading — fixes spelling, grammar, and formatting using surrounding context (e.g. "Hen I got home" → "When", not "Hen")
• Screenplay formatting — detects INT./EXT. headings, character names, dialogue, transitions, and camera directions; formats them automatically
• Respects your voice — won't rewrite prose, change style, or take creative liberty
• Standalone window — opens as its own app with themed title bar and icon (not inside cmd.exe)
• Settings screen — configure API keys, choose preferred provider, browse OpenRouter models
• Scramble animation — corrected characters dissolve through random glyphs before resolving
• Graph-node links — [[wiki-links]] for building interconnected documents
• Scroll indicator — gold position marker appears in the left margin on long documents
• Three LLM providers — Claude (Anthropic), OpenAI, and OpenRouter
• Smart triggers — fires on sentence boundaries (300ms), word gaps (600ms), or idle (1.5s)
• Zero config — works as a plain editor with no API key; set one to enable spell correction

Installation

API keys are saved to your system config directory and persist across sessions.

Configuration

Settings are managed in-app (Tab → ⚙ settings on the title screen). Keys are stored in:

• Windows: %APPDATA%\write\.env
• macOS: ~/Library/Application Support/write/.env

You can also set environment variables directly:

Variable	Purpose
ANTHROPIC_API_KEY	Claude API
OPENAI_API_KEY	OpenAI API
OPENROUTER_API_KEY	OpenRouter API
LLM_PROVIDER	Force a provider (claude, openai, openrouter)
LLM_MODEL	Override the default model (useful for OpenRouter)

Keybindings

Graph-Node Links

Write supports [[wiki-links]] for building interconnected documents.

• Create: Place cursor on a word → Ctrl+G → wraps in [[brackets]]
• Navigate: Cursor on a [[link]] → Ctrl+O → zooms into the linked page
• Back: Esc saves the linked page and returns to the parent

Linked pages are stored alongside your document:

~/Documents/
├── my-essay.md
└── my-essay/
    ├── Character Name.md
    └── Location.md

Compatible with Obsidian, Logseq, and other wiki-link tools.

Screenplay Support

Write detects when you're writing a screenplay and formats elements automatically:

**FADE IN:**

**EXT. DESERT HIGHWAY - DAY**

A heat shimmer ripples across empty asphalt stretching to the horizon.

**WIDE SHOT**

A single car appears in the distance.

**JACK**
*(squinting)*
We should have turned left at Albuquerque.

**MARIA**
That's what I said three hours ago.

**CUT TO:**

Supported elements: scene headings (INT./EXT.), character names, dialogue, parentheticals, transitions (CUT TO, FADE IN/OUT, SMASH CUT), camera directions (CLOSE UP, WIDE SHOT, PAN, TRACKING SHOT, POV, OVER THE SHOULDER), shot descriptions (ANGLE ON, INSERT, MONTAGE), and continuation markers.

Regular prose dialogue stays inline with quotation marks — screenplay formatting only activates when the document contains screenplay structure.
