It eliminates manual data entry by leveraging Tesseract OCR, Google Gemini AI, and Airtable, with optional Telegram notifications. The workflow is ideal for freelancers, small businesses, and finance teams who need a lightweight and automated solution for handling invoice data. 🔑 Features ✅ Supports JPG, PNG, and PDF invoices 🧠 Automatically extracts: Invoice Number, Invoice Date (standardized to YYYY-MM-DD), Subtotal, Tax, Total, Currency, Vendor Name, Email, Phone, and Ship-to Address 📤 Sends structured data into Airtable automatically 📬 Sends a Telegram notification once data is processed (optional) 🔁 Triggers automatically when new files are dropped into a folder ⚠️ Disclaimer This workflow uses community nodes (n8n-nodes-tesseractjs, n8n-nodes-pdf-page-extract). It works best on self-hosted n8n or n8n cloud instances where these nodes are available. You must install and configure these nodes before importing the workflow. ⚙️ Setup & Configuration Install Docker with n8n. Mount your folder (e.g., ~/self-hosted-ai/ocr-bot:/shared) so invoices can be dropped into /shared/ocr/. Import the provided JSON workflow into n8n. Replace credentials: Google Gemini API key Airtable base + token Telegram bot token (optional) Drop a sample invoice (PDF/JPG/PNG) into the configured folder. Check Airtable for structured data and Telegram (if enabled) for confirmation. 🧠 Customization Modify the AI prompt to extract additional fields. Replace Airtable with Google Sheets or another database if preferred. Update the Telegram node with your own Chat ID for notifications. 💡 Tip: Add a screenshot of the workflow in n8n to help users quickly understand the node structure.
