The Challenge: AI models are useless if their data is old. The client needed a way to "teach" the AI new policies instantly by just dropping a PDF into a folder.
The Architecture: A webhook-triggered flow that lists files from a Google Drive Inbox. Custom JS nodes convert Docs to text while handling PDFs as binaries. Before upserting, we delete old vectors to prevent "Ghost Data".
"I don't just copy files. I manage Vector Lifecycles."
if (!item.binary && item.json.data) { // Handle Google Doc Export const textContent = item.json.data; item.binary = {; data: Buffer.from(textContent).toString('base64'), mimeType: 'text/plain', fileName: original.name + '.txt' }; } else { // Handle Native Binary (PDF/IMG) item.binary.data.fileName = original.name; } return $input.all();
The Challenge: Standard chatbots hallucinate. The client needed a bot that acted like a trained Sales Rep.
The Architecture: A LangChain Agent with 4 distinct Protocols (Consult, Product Search, Info, Closing). The agent autonomously decides when to query the Inventory DB or capture lead data into Sheets.
Production workflows and interfaces running in the wild.
