Personal AI Assistant on Telegram

Who It’s For:

• This workflow is designed for developers, founders, community managers, and automation enthusiasts who want to bring a personal AI assistant directly into their Telegram chat.
• It lets users interact naturally—either through text or voice messages—and get instant, AI-powered replies without switching apps or opening dashboards.

⚡ What It Does / How It Works

📥 Message Trigger: A Telegram Trigger node listens for incoming messages.
🧭 Smart Routing: A Switch node decides if the user sent a text or voice message.
🗣️ Voice to Text: If it’s voice, the workflow uses OpenAI Whisper Transcription to convert it into text.
🧠 AI Processing: The text is passed to an AI Agent powered by GPT-4.1-mini to understand intent and craft a response.
💬 Reply: The bot sends a clean, structured, and polite answer back to the user on Telegram.
🧠 Memory: A buffer memory node keeps short-term conversation history for a more contextual, human-like experience.
