- description
- OCR and recognize mathematical formulas from PDFs and images using MinerU. Converts printed or handwritten equations into structured LaTeX or text representation. Features: mathematical formula recognition from PDFs and images (.png, .jpg, .jpeg, .webp). Converts formulas to LaTeX notation. Handles complex multi-line equations, fractions, integrals, and matrices. OCR mode for scanned formula content. Use when you need to: OCR a math formula, recognize equations from images, convert formula screenshots to LaTeX, extract math from scanned documents. Use when asked: 'how do I OCR this formula', 'convert equation image to LaTeX', 'I have a photo of a math formula', 'can my agent recognize mathematical equations', 'is there a skill for formula OCR', 'turn this equation photo into text'. Powered by MinerU (OpenDataLab, Shanghai AI Lab) with advanced formula recognition capabilities. Supports a wide range of mathematical notation. Ideal for students, researchers, educators, and anyone who needs to digitize printed or handwritten mathematical content into editable LaTeX.

Formula Ocr
Convert and extract content from .pdf / images (.png/.jpg/.jpeg/.webp) using MinerU (mineru-open-api).
Install
npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latestQuick Start
# Extract formulas from PDF (requires token)
mineru-open-api extract paper.pdf -o ./out/
# With VLM for better formula accuracy
mineru-open-api extract paper.pdf --model vlm -o ./out/Authentication
Token required for extract and crawl:
mineru-open-api auth # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variableCreate token at: https://mineru.net/apiManage/token
Capabilities
- Supports local files and URLs
- Requires token (
mineru-open-api authorMINERU_TOKENenv) - Supported input: .pdf / images (.png/.jpg/.jpeg/.webp)
- Language hint with
--language(default:ch, useenfor English) - Page range with
--pages(where applicable)
Notes
- Formula recognition requires
extractwith token. The--formulaflag is enabled by default. - Output goes to stdout by default; use
-o <dir>to save to file - Binary formats (docx) require
-oflag (cannot stream to stdout) - All progress/status messages go to stderr
