n8n AI Agent: Chat with Supabase Storage & Google Drive Files

Chat with your Supabase files and Google Drive documents using an n8n AI Agent

This n8n automation workflow builds an AI-powered agent that can upload files into Supabase Storage, react to file changes in Google Drive, parse documents into structured data, and answer user questions based on what’s been stored—turning document management into a fast, searchable experience.

What this workflow does

• Collect and ingest documents: Files can be uploaded into Supabase Storage.
• React to changes in Google Drive: The workflow activates processes when file changes occur in Google Drive.
• Retrieve and parse content: Stored documents are retrieved and converted into a structured format suitable for querying.
• Answer queries with an AI agent: Users can ask questions, and the agent responds using the saved document data.

As a result, you avoid repetitive manual steps and enable rapid retrieval and analysis of information from uploaded documents.

Use cases

• Developer or data-science workflows: Automatically process uploaded files and query their contents without manual searching.
• Business teams managing document libraries: Turn Google Drive documents into an AI-assisted knowledge source backed by Supabase storage.
• Faster information retrieval: When Drive files change, re-process and keep your structured dataset up to date for question answering.

Technical details

• Integrations: Supabase Storage and Google Drive
• Workflow logic & nodes: if, set, wait, merge, switch, webhook
