# Getting started with Katchy > Install Katchy, grant the two macOS permissions, hold the hotkey, ask your first question. Katchy lives in your menu bar. There's no chat window to learn, no settings to wade through — just a hotkey, your voice, and an answer. This page walks through the first five minutes. ## 01. Install 1. Download the `.dmg` from . About 860 MB on Apple Silicon and Intel. 2. Open the `.dmg` and drag the Katchy icon into your Applications folder. 3. Launch Katchy from Spotlight or Applications. The icon takes its place in the menu bar. ## 02. Grant two macOS permissions On first launch macOS asks for two permissions. Both are required for Katchy to do its job. - **Accessibility** — so the cursor overlay can point at the right button on your screen. - **Screen Recording** — so Katchy can see what you see when you ask about it. Screen frames stay on your Mac. Vision processing runs locally; the abstracted question text is the only thing that ever leaves the device, and only when a frontier model is needed. If you skipped a prompt by accident, open System Settings → Privacy & Security and enable Katchy under both panes. ## 03. Hold the hotkey **Control + Option** — hold anywhere on macOS to wake Katchy. The hotkey works anywhere — full-screen Xcode, a fullscreen video, a Spaces switch. Hold it, speak a question, release. Katchy answers in your ear. ## 04. Ask your first question Try one of these out loud while looking at the relevant window: - "What does this error mean?" - "Why isn't this test passing?" - "Walk me through this function." - "Tidy up my Desktop." - "Reply to Sara — yes to dinner Friday, no to wine." Katchy reads the pixels on your screen, picks the best frontier model for the question (Claude, GPT, or Gemini), and answers in your ear within about a second.
