It's perfect for busy professionals, personal productivity enthusiasts, and anyone looking to streamline their scheduling.\n\n## What it does\n1.  **Triggers on Labeled Email**: The workflow starts when a new email is given a specific label in Gmail (e.g., \"Scheduled\").\n2.  **Parses Event with AI**: The email's content is sent to Google Gemini to extract structured event data: title, start time, end time, location, and a description.\n3.  **Creates Calendar Event**: Using the data extracted by the AI, a new event is automatically created in your Google Calendar.\n4.  **Sends Confirmation Email**: A confirmation email is sent back to you, containing a summary of the created event, a direct link to edit it in Google Calendar, and the original email content for reference.\n\n## Requirements\n- A Google account for Gmail and Google Calendar.\n- Credentials for the Google Gemini API.\n- An active n8n instance.\n\n## How to set up\n1.  **Credentials**: Configure your credentials for the 'Gmail Trigger', 'Google Gemini Chat Model', 'Create Google Calendar Event', and 'Send Confirmation Email' nodes.\n2.  **Gmail Trigger**: Select the 'Gmail Trigger' node. In the 'Label Ids' field, choose the Gmail label you want to use to trigger the workflow (e.g., a label named `Scheduled`).\n3.  **Confirmation Email**: Select the 'Send Confirmation Email' node. In the 'Send To' field, enter the email address where you want to receive the confirmation email (e.g., `YOUR_EMAIL_ADDRESS@example.com`).\n4.  **Activate Workflow**: Save and activate the workflow.\n\n## How to customize\n- **AI Prompt**: You can modify the prompt in the 'Parse Event with AI' node to better suit your needs. For example, you can change the default timezone (`JST (UTC+9)`) or add rules for how to handle recurring events.\n- **Email Content**: Customize the subject and body of the confirmation email in the 'Send Confirmation Email' node.\n- **Calendar Options**: In the 'Create Google Calendar Event' node, you can add more event details, such as attendees or reminders."
