Document Automation System
An end-to-end automation that extracts structured intelligence from documents received via UI, Email, or WhatsApp and stores it cleanly in MongoDB.
Problem Statement
The Solution
Automation Overview
We built a complete document automation pipeline that accepts files from multiple channels (UI, Email, WhatsApp), analyzes them with AI, extracts structured data, and stores the results in MongoDB. The system doesn’t just read text — it understands document context, structure, and intent.
Multi-Channel Document Intake
The workflow accepts documents from Web UI uploads, Email attachments, and WhatsApp messages. All inputs are normalized into a single processing pipeline, regardless of where the document comes from.
AI-Powered Document Understanding
Using a Google Gemini–powered AI agent, the system analyzes each document and extracts title, department, summary, key points, keywords, and business labels. The AI understands context instead of relying on rigid templates.
Physical & Structural Element Detection
Beyond plain text, the workflow detects tables, signatures, layout indicators, multi-page structures, and embedded sections. This allows the system to differentiate between content types like invoices, contracts, reports, or internal documents.
Language & Classification Detection
The automation automatically detects the document language, applies internal business labels, classifies documents by purpose or department, and normalizes outputs for consistent storage.
Clean Structured Output (Core Intelligence)
All extracted data is converted into a clean JSON structure that includes metadata, extracted fields, AI-generated summary, detected elements, and confidence indicators. No raw blobs. No messy text.
MongoDB Storage & Indexing
The final structured output is stored in MongoDB, making it searchable, filterable, and ready for dashboards, RAG systems, or analytics. This creates a reliable document intelligence database.
Error Handling & Reliability
The system includes file-type validation, empty-content detection, AI fallback handling, safe retries, and logging for failed documents. Documents never silently fail.
Integrations & Connected Systems
UI Upload Forms – manual submissions; Email – attachment intake; WhatsApp – document ingestion; Google Gemini – AI extraction & understanding; MongoDB – structured storage; n8n – orchestration, validation, routing.
