DoclingOCR
IBM Research's open-source document layout and table extraction engine — freely available to everyone. Convert complex double-column academic papers, LaTeX formulas, and borderless tables into cleanMarkdown, LaTeX, and Excel.
Docling OCR Instant Web Converter
Drag & drop any PDF or scanned paper here
Supports academic papers (arXiv), double-column PDFs, financial 10-K filings, and documents with complex mathematical equations.
Next-Gen Document Intelligence
Why Traditional OCR Fails Where Docling Excels
PDFs are visual fossils with zero semantic structure. Conventional tools like Tesseract or Adobe OCR only extract raw bounding boxes. Docling uses deep vision models to reconstruct human reading logic.
TableFormer Architecture
State-of-the-art table structure recognition. Accurately decodes complex financial statements, multi-level headers, and borderless tables with zero column merging.
Learn about TableFormer→Double-Column Reading Order
No more interleaved garbled text. Docling segments columns geometrically, following the natural left-to-right academic reading flow across full multi-column pages.
Read Academic Paper Guide→Native LaTeX Formulas
Translates mathematical equations, Greek notation, matrices, and fractions directly into standard LaTeX / KaTeX code, ready for Obsidian, Notion, or Overleaf.
Compare with Mathpix→Zero-Code Web UI
Skip installing Python, PyTorch, and CUDA. SheetParser hosts Docling on high-speed cloud GPUs with instant drag-and-drop conversion.

How to Run Docling OCR: CLI vs Web UI
Choose the right path for your workflow: terminal-based Python scripting for developers, or instant zero-setup browser UI on SheetParser.
Option 1: Python CLI & SDK
Best for software engineers building automated pipelines or processing millions of documents locally with GPU.
converter = DocumentConverter()
result = converter.convert("document.pdf")
print(result.document.export_to_markdown())
- ✓ Full programmatic control over OCR pipeline
- ✗ Requires Python 3.10+, PyTorch, and 4GB model weights
- ✗ Slow on standard CPUs (requires NVIDIA CUDA for speed)
Option 2: SheetParser (Online Web GUI)
Best for researchers, bookkeepers, analysts, and students who want instant Docling OCR conversions in their browser without code.
Drag & Drop in Browser
Upload your PDF or scanned document directly into the web interface.
GPU Cloud Acceleration
Runs on enterprise NVIDIA GPUs, completing 100-page filings in seconds.
1-Click Multi-Format Export
Export clean Markdown, LaTeX equations, TSV for Excel, or QuickBooks .QBO.
- ✓ Zero installation — works on Mac, Windows, iOS, Chromebook
- ✓ 1-Click Copy for Excel with zero merged columns
- ✓ Free daily conversions with generous tier
Side-by-Side Analysis
Docling vs Mathpix vs Traditional OCR
See how IBM's open-source Docling architecture and SheetParser compare against legacy converters.
| Feature / Capability | Docling Web UI (SheetParser) | Docling Python CLI | Mathpix Snip | Marker OCR | Traditional (Tesseract/Adobe) |
|---|---|---|---|---|---|
| Setup & Requirements | Instant Browser Access (0s, no install) | Python 3.10+, PyTorch, CUDA, 4GB weights | Desktop App / Account required | PyTorch, Transformers, Python | Local binary or Adobe monthly plan |
| Double-Column Reading Order | 100% Geometry-Aware (IBM Layout) | 100% Geometry-Aware | High accuracy | High accuracy | Fails (interleaves horizontal text) |
| TableFormer Deep Learning | Full TableFormer + Reconciliation Checks | Full TableFormer model | Proprietary table model | Heuristic / Layout model | Fails on borderless/merged tables |
| LaTeX Equation Recognition | Native LaTeX & KaTeX live preview | Raw LaTeX in markdown string | Native LaTeX | Latex formula model | Garbled unicode characters |
| Excel (TSV) & QBO Export | 1-Click Copy for Excel + QBO / CSV | Requires custom Python parsing scripts | TSV / CSV export (manual cleanup) | Markdown tables only | Merged columns & broken rows |
| GPU Processing Speed | Cloud T4 / A10G GPU (2-3s per page) | Depends on your local GPU / CPU | Cloud servers (fast) | Local GPU required for speed | CPU-based (slow for scans) |
| Pricing & Free Tier | Free daily tier + Affordable Pro | Free open source (self-host GPU) | $9.99/mo (very limited free snips) | Free open source (GPL license) | Adobe Acrobat ($239/year) |
