Conversational Google Calendar Bot with Claude AI & Telegram

This workflow transforms Telegram into a smart conversational interface for Google Calendar management. Using Anthropic's Claude 3.5 Haiku as the primary AI (with OpenAI GPT-4.1-mini fallback), it processes natural language commands to create events, check for time conflicts, and confirm actions. Triggered by Telegram messages, the LangChain Agent parses intent, queries the calendar, and either books the slot or suggests alternatives.

Key benefits include hands-free scheduling without app-switching, conflict prevention to avoid double-bookings, and seamless integration of top AI models for accurate understanding of vague queries like 'meeting tomorrow at 3pm'. It's ideal for busy professionals, reducing manual calendar entry time by 80% through voice-to-text compatibility in Telegram.

Use cases: Quick event creation during commutes ('Dentist on Friday 2pm'), all-day reminders ('Renew passport August 20th'), or rescheduling with conflict detection. Setup requires API credentials for Telegram, Google, Anthropic, and OpenAI; configure chat ID and calendar selection for instant deployment. Perfect for personal productivity enhancement.
