Document AI
Docugami is an AI-powered document intelligence platform that understands the structure and meaning of complex business documents like contracts, invoices, HR files, and insurance forms. Unlike simple OCR or chat-over-PDF tools, Docugami builds a deep semantic understanding of your document sets, extracting structured data, identifying clauses and terms, and enabling cross-document analysis at scale. Founded by former Microsoft engineering leaders, it targets enterprises that process high volumes of complex documents and need reliable, structured data extraction.
Document AI
Cloud document processing platform that automates data extraction and classification with industry-leading OCR accuracy. Processes invoices, receipts, forms, and custom document types to optimize document workflows and improve processing efficiency.
💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
Marker benchmarks favorably against both. Compared to LlamaParse, Marker is faster and open-source. Compared to Docling, Marker focuses on markdown/JSON output quality while Docling provides richer structured output with bounding boxes. Marker's LLM-enhanced mode often produces the highest overall accuracy.
Not technically — it runs on CPU and Apple MPS — but practically, yes for any batch workload. CPU processing is 4-10x slower. GPU processing achieves roughly 25 pages/second on H100 hardware in batch mode. For a handful of documents, CPU works fine.
Yes, through integrated Surya OCR supporting 90+ languages. Scanned documents at 300+ DPI produce good results. Use the --force_ocr flag to ensure all content goes through OCR. Lower-quality scans will have reduced accuracy.
The --use_llm flag pairs Marker's layout detection with an LLM (Gemini Flash by default) for post-processing. It improves table formatting, handles inline math, merges split tables, and extracts form values. Use it when document accuracy matters more than processing speed — it adds cost and latency but produces measurably better output.
