on your mac
What you can do
benchmark
Know what your Mac can do
Measure its memory bandwidth, GPU compute, and how fast it reads a prompt and writes an answer. Real numbers from your Mac, never estimates.
fit
See which models fit, and why
Every model drawn against your Mac's memory at the context window you pick: fits, tight or won't fit, with the reason in plain sight.
one click
The most capable model, running
Get started picks the most capable model your Mac can run (or the one with the longest context window), downloads it and starts it.
chat
A private chat, several conversations
Keep as many conversations as you like, rename them, come back to them. They live on your Mac.
documents
Bring your documents
Attach text files and PDFs and ask about them. The document is read on your Mac and goes nowhere else.

Models that can see
aituner recommends vision models too, shows how they fit, and runs them inside the app on your Mac.
live
Watch your Mac as it answers
GPU, CPU, memory and the model's speed, live beside the chat, and the full Monitor one click away.

FAQ
Questions
Do I need the Terminal, Python or Homebrew?
No. The Mac App Store app carries everything it needs to run models inside it. You install it from the Mac App Store, press Get started, and it does the rest.
What is the App Sandbox?
Apple's App Sandbox is a protection built into macOS that every Mac App Store app runs inside. The app can reach only what macOS allows it to: its own folder, the network, and files you choose to give it.
Does anything leave my Mac?
Your chats, your documents and what the models answer stay on your Mac. aituner shares each benchmark run anonymously (the Mac's model, chip, memory and the measured numbers, with the approximate city) to build the public stats; the privacy page lists everything it sends. There is no tracking and no advertising.
Do I need a license key or an account?
No license key: aituner is installed and updated by the Mac App Store. You sign in with Apple once, for a free private account: it keeps who you are and which devices are yours, and lets you see your Macs and manage your devices at account.aituner.app. Your chats, models and results stay on your Mac.
