Description
📅 Google Calendar Assistant with GPT-4o
Your personal AI agent to manage your calendar with natural language — powered by GPT-4o
🧠 What Problem Does It Solve?
Manually handling calendar events is repetitive, time-consuming, and error-prone. This smart AI workflow solves that by allowing users to:
➤ Create events in Google Calendar
➤ Retrieve events using plain-language queries
➤ Automatically understand time phrases like “next Monday” or “this weekend”
⚙️ How It Works
🔹 Chat message triggers the workflow
🔹 User message is processed by GPT-4o
🔹 GPT-4o decides whether to create or retrieve events
🔹 Two built-in tools handle actions:
📌 Get Events – Fetches events in a specified date range
🛠️ Create Events – Adds new calendar entries with title, time, and description
🔹 The agent confirms inputs with the user before proceeding
🔹 Short-term memory keeps recent context (last 5 messages)
