Description

This workflow creates a powerful AI assistant in Telegram that helps you manage your tasks in Notion. The assistant leverages OpenAI's language models to understand natural language commands, process voice messages, and maintain context through conversations.

Key features:
Processes both text and voice messages in Telegram
Transcribes voice messages automatically
Maintains conversation context with memory
Manages Notion tasks through a custom tool:
• List all tasks
• Add new tasks with priority (today/later)
• Complete or uncomplete tasks
• Change task timing

The workflow consists of two main parts:
AI Agent section: Handles Telegram connectivity, message processing, voice transcription, and conversation management
Notion Tool section: Implements the custom tool that connects to your Notion database, allowing the AI to interact with your tasks

Setup requires:
A Telegram bot token
OpenAI API credentials
Notion integration token and database ID

Example Notion Database


Perfect for personal productivity, team task management, or as a foundation for building more complex AI assistants with additional tools.
