Data Flow

flash-extract sends the document to the MinerU API (mineru.net) for processing and returns Markdown. This is a stateless API call — no account, no persistent storage. MinerU is an open-source project by OpenDataLab (Shanghai AI Lab): https://github.com/opendatalab/MinerU

Notes

Output is Markdown only; images/tables/formulas may be replaced with placeholders
For larger files (up to 200MB/600 pages) or precision extraction with full assets, use mineru-open-api extract (requires auth via mineru-open-api auth)
If the CLI cannot be installed via npm/uv/go, download it from https://mineru.net/ecosystem?tab=cli
