Getting started

Open the installer. On Windows, if you see "Windows protected your PC", choose More info, then Run anyway. On a Mac, drag Simbo Speak into Applications, then open it. If your Mac says it can't check the app, go to System Settings, then Privacy & Security, and choose Open Anyway. You only do this once.
Sign in or create a free account in Settings. You can also use Simbo without an account by connecting your own AI key.
On a Mac, allow Accessibility. Go to System Settings, then Privacy & Security, then Accessibility, and turn on Simbo Speak. This lets the shortcut copy and paste for you.
Select text anywhere and press the shortcut: Ctrl Shift Space on Windows, ⌘ Shift Space on Mac. Fix it, then choose Replace in app.
Turn on voice typing (optional). In Settings, under Voice typing, download a speech model once (57 MB). Then press Ctrl Alt Space (⌃ ⌥ Space on Mac) in any app, talk, and press it again.

Simbo Speak checks for new versions on its own and asks before restarting. Everything you set up stays as it was. See what's new.
