Calendar Read & Write
Create, rename, delete, and look up events. Ask naturally — "add a dentist at 3pm Friday" — and it appears instantly in the iOS Calendar app.
🎙️
Voice Input
Tap the mic and speak. WhisperKit transcribes on-device, no audio ever sent to a server.
⏱️
Free Time Finder
Ask "when am I free this afternoon?" and LucidPal checks your calendar for conflicts automatically.

Siri Shortcuts
Ask a question, check your schedule, add an event, or find free time — all hands-free from Siri or the Shortcuts app.
