See a quick walkthrough of its capabilities and user flow. **How it works:** * User uploads a PDF document to a Telegram bot. * The workflow processes the PDF, creates embeddings using Google Gemini, and stores these embeddings in a **Supabase vector table**. * Users then ask questions to the bot. * The workflow performs a **vector search in Supabase** to find relevant document chunks based on the user's query. * Google Gemini uses the retrieved relevant chunks to generate an intelligent answer. * The bot sends the formatted answer back to the user on Telegram, utilizing **HTML markup** for enhanced presentation. **Set up steps:** Setup should take approximately 15-20 minutes. 1. Import the workflow into your n8n instance. 2. Configure credentials for Telegram, Google Gemini, and Supabase. 3. Set up your Supabase vector table using the provided SQL script. 4. Activate the workflow. Detailed setup instructions, including how to get API keys and configure nodes, are available in the sticky notes within the workflow itself.
