Multi-User Telegram Bot: YouTube Summaries & Repurposing with GPT-4o

This n8n workflow powers a sophisticated Telegram bot designed for content creators, marketers, and educators. It listens for messages: if a YouTube link is detected, it extracts the video ID, fetches the transcript via RapidAPI, cleans it, and uses GPT-4o to generate summaries or repurposed content like LinkedIn posts or tweet threads. Non-link messages trigger general AI chats with per-user memory via chat_id, ensuring personalized, context-aware responses without cross-user interference.

Key features include multi-user support, follow-up prompts (e.g., 'Make it shorter' or 'Turn into a tweet'), and seamless integration of Telegram, RapidAPI, and OpenAI. The workflow handles transcript cleaning and advanced AI prompting for high-quality outputs, saving hours of manual video processing.

Benefits: Automate content repurposing to boost productivity; ideal for solopreneurs scaling social media or teams managing video libraries. Use cases span marketing campaigns, educational recaps, and viral thread creation. Setup requires only API keys; customize prompts via sticky notes for tailored results.
