What is Calendar AI
Quickly add events to Google Calendar using natural language or images. Just type or paste a screenshot! Add events to Google Calendar in seconds — just type naturally or paste a screenshot!
🚀 HOW IT WORKS 1. Simply describe your event in plain language:
- "Meet with Sarah tmr 3pm"
- "Team lunch Fri noon at Pizza Hut"
- "Call [email protected] next Mon 10am"
Then hit Enter, your input will be transformed into a calendar event.
2. You can also paste/upload a screenshot of the event. The AI understands your input and creates a calendar event instantly.
- Use (Shift + Ctrl + Cmd + 4) to capture a screenshot, open the extension, add info if needed, then hit Enter.
- Also supports uploading images.
