Sheet 00 / Arcwright / AI coding editor for Windows, macOS and Linux
The AI editor that asks first.
Arcwright is a desktop code editor with four ways to work with AI. Every edit arrives as a diff. Every agent action is checked by the app, not the model, and written to a log. One shortcut stops the agent dead.

Agent Forge
Terminal
A short animation: an AI agent in Arcwright's Forge mode reads a route, asks permission, writes a rate limiter, edits the login route as a diff, writes a test and runs it. Four tests pass.

export function createLimiter(max, windowMs) { const hits = new Map(); return function allow(key, now = Date.now()) { const recent = (hits.get(key) || []).filter((t) => now - t < windowMs); if (recent.length >= max) return false; recent.push(now); return true;

Applied as one step. Undone as one step.
export function Pricing() { return ( > );
<section className="tiers"> <Tier name="Hobby" price="0" />The model proposes. The app decides.
- Permission
- Forge asks before it acts by default. The check runs in the app, outside the model's reach, on every action it takes.
- Record
- Each action is written to an activity log you can read afterwards.
- Stop
- Ctrl Alt Shift H halts the agent immediately.
- Undo
- Sketch applies as one undoable edit. Blueprint applies in one step and has Undo all.
- Secrets
- Keys are stored by the main process, encrypted with DPAPI, Keychain or libsecret. Never in
config.json. Never sent to the interface. - Hosted key
- On Arcwright Cloud the provider key exists only on the server. Your app holds a short-lived token tied to your device.
Pay once, pay us, or pay nobody.
Switch backend any time. The editor, modes and diffs behave the same on all three.
