This workflow automates the process by vectorizing documents and enabling AI-powered interactions, making it easy to query and retrieve context-based information from uploaded files.\n\nThe workflow integrates Supabase with an AI-powered chatbot to process, store, and query text and PDF files. The steps include:\n- Fetching and comparing files to avoid duplicate processing.\n- Handling file downloads and extracting content based on the file type.\n- Converting documents into vectorized data for contextual information retrieval.\n- Storing and querying vectorized data from a Supabase vector store.\n\n",

How this works
Easily query your documents through natural language conversations, receiving precise answers backed by your own files without sifting through pages manually. This workflow suits teams handling knowledge bases, support docs, or research materials, enabling quick insights for non-technical users. It starts by fetching files via HTTP requests, loading and splitting the content with the default data loader and recursive text splitter, then generating embeddings using OpenAI to power intelligent searches stored in Supabase.
Use this when you need an interactive chat interface for document retrieval in apps or chatbots, especially with event-driven triggers for real-time queries. Avoid it for massive document sets exceeding Supabase limits or non-text files like images, where specialised loaders are needed. Common variations include swapping OpenAI for other embedding providers or adding vector stores like Pinecone for larger scales.
