Unstructured.io is a capable document processing library with broad format support. The trade-off: it's complex to self-host, requires Python and Docker, and demands ongoing infrastructure maintenance.
BlazeDocs delivers clean, RAG-ready Markdown via a hosted API — no infra, no Docker, no Python environment. Just an API key and one HTTP call.

Self-hosting Unstructured.io means managing Docker containers, Python environments, system-level OCR dependencies (Tesseract, Poppler), and keeping it all running. BlazeDocs is fully hosted — you call an API, you get Markdown.
Unstructured.io outputs element-level JSON (titles, text, tables as separate objects) which requires post-processing to turn into usable Markdown. BlazeDocs outputs clean GFM Markdown directly — ready to chunk, embed, or display without extra steps.
Unstructured.io is a parsing library. BlazeDocs is a complete platform: conversion, Document AI chat, MCP server for agent integration, Obsidian/Notion export, and SOC2 compliance — all included.
Yes — but it outputs element JSON, not Markdown directly. You'll need to write post-processing code to stitch elements into a Markdown document. BlazeDocs outputs clean Markdown immediately, which is faster for most RAG and AI workflows.
It requires Docker, Python, and system-level dependencies like Tesseract and Poppler. Getting the "hi_res" strategy (best quality) running requires GPU support or significant compute. BlazeDocs has none of this overhead — sign up, get an API key, start converting.
Unstructured.io open-source is free but you pay for the infrastructure. Their Serverless API charges per page which scales unpredictably. BlazeDocs Pro is $17.99/month — flat rate, 1,000 pages, no surprise bills. For teams running regular document pipelines, the total cost of ownership is typically lower with BlazeDocs.
BlazeDocs outputs Markdown that chunks naturally by heading and section — ideal for RAG. Unstructured.io gives you more granular element-level control which suits complex multi-format ETL pipelines. For PDF-to-RAG specifically, BlazeDocs is the faster, simpler path.
One API key. RAG-ready Markdown with tables, headings, and structure preserved. Free tier, no card required.
