Installation

From GitHub Repository

pip install git+https://github.com/tidyeval/docinfer.git

From Local Development

Clone the repository and install in editable mode:

git clone https://github.com/tidyeval/docinfer.git
cd docinfer
pip install -e .

Quick Start

Using uvx (Recommended)

Run directly without installation using uvx:

uvx --from git+https://github.com/tidyeval/docinfer.git docinfer <path-to-pdf>

Note: Once published to PyPI, you'll be able to run uvx docinfer <path-to-pdf> directly.

CLI Usage

If you've installed the package locally, run directly:

docinfer <path-to-pdf>

Options

• --model MODEL - Specify the Ollama model (default: gemma3:4b)
  • Example: docinfer document.pdf --model gemma2
• --json - Output as JSON instead of formatted text
• --no-ai - Skip AI analysis and show embedded metadata only
• --export FILE - Export results to JSON file
• --quiet - Suppress progress output

Python API

from docinfer.services.pdf_extractor import PDFExtractor
from docinfer.services.ai_analyzer import AIAnalyzer

# Extract PDF content
extractor = PDFExtractor()
content = extractor.extract("document.pdf")

# Analyze with AI
analyzer = AIAnalyzer()
metadata = analyzer.analyze(content)
