How it works

Three steps. No new tools
to learn.

01 — DESCRIBE

Say what you want in plain English

Muse reads your actual codebase — not a template. It understands your stack, conventions, and tests.

muse "fix the checkout race
  condition when coupon is empty"
02 — REVIEW

Inspect the diff before anything changes

Every edit is a patch you can read, tweak, or reject. Nothing is applied until you say so.

+  if (!coupon) return cart.total
-  applyDiscount(coupon)
03 — APPLY

Apply, test, ship

Runs your checks, keeps the change local. Commit when you're happy. No lock-in, no cloud required.

$ muse apply
✓ patched 2 files — tests green
Install

Lightweight by design.

Install in 12 seconds

Single binary. No Docker, no daemon, no account.

Why minimal?

Most tools want your repo in their cloud. Muse stays local, stays small, and stays out of your way. One command, one diff, one decision at a time — so you stay in control and your codebase stays yours.
