Finds AiTuner by itself
Open AiTuner Code: it finds AiTuner on your Mac and asks once. Choose Allow in AiTuner, and the key goes to your Keychain. Nothing to paste.
aituner code
A coding agent that runs on your own Mac
Open a git repository, ask, review the diff, apply. The model is the one AiTuner runs on your Mac, so your code never leaves it.
Or with Homebrew:
brew install --cask aituner-app/tap/aituner-code0.1.0 · Apple Silicon, macOS 14+ · notarized · needs AiTuner · SHA-256
a real session
Two bugs fixed, every change reviewed
A failing test in a small Go repository, with Qwen3.6 35B-A3B running in AiTuner on an M1 Max with 32 GB. The agent read the code, showed each edit as a diff to allow, and asked before it ran the tests.
you › The test in this repository fails. Find the bugs in cart.go, fix them,
then run go test ./... to confirm.
▸ view cart_test.go, cart.go
The bug is on line 8: sum += it.Price ignores the quantity.
▸ edit cart.go −1 +1 allowed
▸ bash go test ./... allowed
--- FAIL: Total([{5000 2}]) = 10000, want 9000
The condition sum > 10000 should be sum >= 10000.
▸ edit cart.go −1 +1 allowed
▸ bash go test ./... ok example.com/shop
Two bugs fixed in cart.go. Tests now pass.

Your model, your repository, your review
01 · link
02 · ask
An agent in a real terminal
The agent reads, searches and edits the repository and runs its tests, in a native terminal beside your code. Full screen with ⌘⇧F.
03 · review
Every change is a diff
Each edit is shown before it is made, and Changes lists what the agent did. Drop a change, or commit them all. It never pushes.
models
Switch at any time
Choose any model in AiTuner that can use tools; AiTuner starts it, and the conversation goes on with the new model.
memory
Your repository's notes
AGENTS.md holds your build and test commands and your code style; the agent reads it at every start and can write it for you.
safety
Held to the repository
It cannot read or change files outside the repository you opened, or git's own files, and it has no web tools.
FAQ
Questions
What does AiTuner Code need?
An Apple Silicon Mac with macOS 14 or later, AiTuner running on it, and a model that can use tools, such as Qwen3.6 35B-A3B. AiTuner shows which of your models can, and how much context fits your Mac. During the beta you sign in to AiTuner (free).
Does my code leave my Mac?
No. The agent reads and changes files in the repository you open, and its model is the one AiTuner runs on your Mac. It has no web tools, and it never pushes: you push when you choose to.
Can it break my repository?
It works only inside the repository you open: it cannot read or write outside it, or touch git's own files. Every change is shown as a diff before it is made, every command that does more than read asks first, and Changes in the app lets you drop any change or commit them all.
Can I use Claude Code instead?
Yes. AiTuner's Settings, Coding agents shows the environment that points Claude Code at your local model, with no Anthropic account.
Why is it not on the Mac App Store?
The agent runs your repository's tests and builds, which the App Store's sandbox does not allow. AiTuner Code is signed with AiTuner's Developer ID and notarized by Apple.
