Overview

MarkItDown AI is an independent web app that converts PDF, DOCX, PPTX, XLSX, HTML, CSV, JSON, and XML files into Markdown for use with ChatGPT, Claude, and RAG pipelines. Its free Browser Basic mode runs locally in your browser, so files are not uploaded. A paid Enhanced mode (sign-in required, files uploaded) adds support for complex tables, formulas, and scanned documents. The name echoes Microsoft's open-source MarkItDown library, but the site states it is not the official Microsoft website, and its GitHub repository currently holds only a README, not source code.

The Verdict

Who Should Use MarkItDown AI?

Best For

  • Quick one-off conversions of Office files or PDFs into Markdown for an LLM prompt
  • Privacy-sensitive files you don't want uploaded (Browser Basic stays local)
  • Non-developers who won't install a Python CLI
  • Occasional scanned-PDF jobs via cheap one-time page packs

Not Ideal For

  • Batch or automated pipelines (one local file at a time, no API documented)
  • Teams that want auditable open-source code (the repo has no source)
  • Large documents on the free tier (10MB / 30-page PDF limits)
  • Developers already comfortable with Microsoft MarkItDown, which is free and scriptable

What's Great

  • Browser Basic converts files locally with no sign-in and no upload
  • Covers the common office formats plus HTML, CSV, JSON, and XML
  • Enhanced mode handles complex tables, formulas, and scanned documents
  • Low-commitment pricing: a $1.99 pack and a free 2-page Enhanced trial
Source

Watch Out For

  • GitHub repo is README-only with no code, releases, or community activity, despite an MIT badge
  • README speed figures are self-reported with no methodology
  • Not affiliated with Microsoft despite the similar name
  • Enhanced mode uploads your files; check the retention notice first
  • No independent reviews found yet
