How Intelligent Document Extraction works – behind the scene with LLMs magic

In our previous post, we explored how AI-powered document extraction accelerates revenue growth and transforms business operations. Today, let’s take a look behind the curtain: How does Intelligent Document Processing (IDP) actually work? What’s the secret sauce—especially with the rise of Large Language Models (LLMs)—that makes solutions like Makez.AI so effective at saving time, reducing errors, and unlocking millions in value for modern enterprises?

At its core, IDP is about automating the extraction, classification, and processing of data from all types of documents—whether they’re invoices, contracts, emails, or handwritten notes. Unlike traditional manual data entry or basic OCR, modern IDP leverages a blend of artificial intelligence (AI), machine learning (ML), and natural language processing (NLP) to “read,” understand, and act on information just like a human would—but at a much greater scale and speed16.

The IDP Journey. Let’s break down the typical workflow powering intelligent document extraction

Step 1

Document Capture & Digitization

  • Physical and digital documents are ingested—scanned, uploaded, or emailed into the system.
  • Pre-processing techniques (like de-skewing, noise reduction, and image enhancement) ensure even poor-quality scans become readable for AI.
Step 2

Document Classification

  • AI models automatically recognize and categorize documents by type (e.g., invoice, contract, purchase order) using content, structure, and metadata.
  • This step is crucial for routing documents to the right workflows and applying the correct extraction logic.
Step 3

Data Extraction

  • Here’s where the magic happens: Optical Character Recognition (OCR) converts images or scanned text into machine-readable data.
  • Machine learning and NLP algorithms, often powered by LLMs, extract key information – names, dates, amounts, signatures, tables, and more – from both structured forms and free-form text.
Step 4

Validation & Error Correction

  • Extracted data is checked for accuracy using business rules, fuzzy logic, and sometimes human-in-the-loop review for edge cases.
  • The system flags anomalies, missing fields, or low-confidence results for human validation, ensuring data integrity.
Step 5

Integration & Automation

  • Clean, structured data is seamlessly pushed into downstream business systems – CRMs, ERPs, finance tools – triggering automated workflows like approvals, reconciliations, or compliance checks.

Recent breakthroughs in LLMs (think GPT-4, Claude, etc.) have taken document extraction to a new level

• Deep Understanding of Unstructured Data: LLMs can interpret context, intent, and relationships within complex documents—making sense of emails, contracts, or reports that don’t follow a fixed template2.
• Multimodal Extraction: Advanced IDP systems now process not just text, but also tables, images, and charts, integrating insights across different data types for a holistic view2.
• Continuous Learning: LLMs improve over time, learning from corrections and new document types, so accuracy and flexibility keep getting better6.

Why This Matters

Real Business Value

For CIOs and business leaders, the impact is tangible.

  • Faster Processing : What once took hours or days is now done in minutes, accelerating sales cycles and cash flow.
  • Fewer Errors : Automated extraction reduces costly mistakes and compliance risks.
  • Massive Cost Savings : By eliminating manual data entry and reducing the need for large operations teams, organizations can save millions annually.
  • Scalability : As document volumes grow, AI-powered IDP scales effortlessly—no need to hire more staff to keep up.
