PDFs have become the backbone of digital documentation compact, shareable, and ideal for preserving layouts. But when it comes to extracting structured data, especially from tables or complex layouts, traditional PDF parsers fall short.

That’s where Kite steps in combining intelligent AI models with seamless PDF processing to turn chaotic documents into clean, structured data.

Traditional Methods to Parse PDF Files

1. Copy-Pasting

Still the go-to method for quick tasks, but highly unreliable. Copying tables or structured content often breaks formatting and introduces errors.

  • Works for: Simple, text-only PDFs

  • Fails when: PDFs have tables, complex formatting, or scanned content

2. Manual Data Entry

When PDFs are scanned or poorly formatted, teams often resort to typing data manually. It’s slow, costly, and prone to human error.

  • Works for: Accuracy when done right

  • Fails when: You need scale or speed

3. OCR Tools

OCR (Optical Character Recognition) can convert scanned images into text, but that’s just the beginning. Extracting structured tables or multi-column content is still a big challenge.

  • Works for: Converting images to text

  • Fails when: You need accurate extraction of layouts, tables, or multi-language content

4. PDF Parsing Libraries (like PyPDF2, PDFMiner, pdfplumber)

These libraries let developers build custom solutions to extract data from PDFs. But they’re often brittle failing when the document structure varies slightly.

  • Works for: Technical teams with consistent document formats

  • Fails when: You have varied layouts or non-standard tables

5. Outsourced Data Services

Hiring third-party firms to extract data manually can work — but it's expensive, slow, and a security risk.

  • Works for: One-off, large batch tasks

  • Fails when: You need automation, speed, or confidentiality

Why These Methods Fall Short

Despite their utility, traditional methods come with major downsides:

  • Inconsistent Output: Slight layout changes break automation

  • Poor Table Detection: Extracted tables often lose alignment or values

  • Privacy Risks: Sharing sensitive files with third parties raises compliance concerns

  • Scalability Issues: Manual or semi-automated methods can’t handle bulk data extraction

  • Zero Context Awareness: They can’t “understand” document content or structure
