How to Get API Keys

Using LinguaAI on Mac

Keyboard Shortcut Access

The fastest way to use LinguaAI is with keyboard shortcuts:

  1. Select text in any application
  2. Press your keyboard shortcut
  3. LinguaAI processes the text with your assigned prompt

Configure shortcuts and their assigned prompts in LinguaAI settings. There are no default shortcuts—you create the ones that work for your workflow.

Menubar Access

Click the LinguaAI icon in your menubar to access the full chat interface, manage prompts, switch models, and configure settings.

Virtual Machine Usage

Running Windows through Parallels or another VM? Three-key shortcuts may not trigger when the VM is in focus.

Solution: Use two-key shortcuts instead. For example, use ⌃T instead of ⌃⌥T. Configure this in Settings → Shortcuts.

Ensure your two-key combinations don't conflict with shortcuts in your Windows applications like Trados or MemoQ.
