🚀 Quick Start

Installation

Option 1: Using pip (Recommended)

# Install from PyPI with all features (recommended)
pip install noteparser[all]

# Install with AI features only
pip install noteparser[ai]

# Install basic version
pip install noteparser

# Install from source with all features (recommended)
git clone https://github.com/CollegeNotesOrg/noteparser.git
cd noteparser
pip install -e .[dev,all]

Option 2: Development Installation

# Clone the repository
git clone https://github.com/CollegeNotesOrg/noteparser.git
cd noteparser

# Create a virtual environment (recommended)
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

pip install -e .[ai]      # AI features only

Note: As of v2.1.0, all dependencies are managed through pyproject.toml. The requirements.txt files are maintained for compatibility but using pip extras is the recommended approach.

System Dependencies

Some features require system packages:

# Ubuntu/Debian
sudo apt-get update
sudo apt-get install -y \
    tesseract-ocr \
    tesseract-ocr-eng \

Python API

import asyncio
from noteparser import NoteParser
from noteparser.integration import OrganizationSync

# Initialize parser with AI capabilities
parser = NoteParser(enable_ai=True, llm_client=your_llm_client)

# Parse single document
result = parser.parse_to_markdown("lecture.pdf")
print(result['content'])

# Parse with AI enhancement
async def ai_parse():
    result = await parser.parse_to_markdown_with_ai("lecture.pdf")
    print(f"Content: {result['content']}")
    print(f"AI Insights: {result['ai_processing']}")

asyncio.run(ai_parse())

# Query knowledge base
async def query_knowledge():
    result = await parser.query_knowledge(
        "What are the key concepts in machine learning?",
        filters={"course": "CS101"}
    )
    print(f"Answer: {result['answer']}")
    for doc in result['documents']:
        print(f"- {doc['title']} (relevance: {doc['score']:.2f})")

asyncio.run(query_knowledge())

# Batch processing
results = parser.parse_batch("notes/", output_format="markdown")

# Organization sync
org_sync = OrganizationSync()
sync_result = org_sync.sync_parsed_notes(
    source_files=["note1.md", "note2.md"],
    target_repo="study-notes",
    course="CS101"
)

🤖 AI Services Setup

NoteParser can operate in two modes:

Standalone Mode (Basic)

Works without external AI services - provides core document parsing functionality.

AI-Enhanced Mode (Recommended)

Requires the noteparser-ai-services repository for full AI capabilities.

# Clone and start AI services
git clone https://github.com/CollegeNotesOrg/noteparser-ai-services.git
cd noteparser-ai-services
docker-compose up -d

# Verify services are running
curl http://localhost:8010/health  # RagFlow
curl http://localhost:8011/health  # DeepWiki

# Test AI integration
noteparser ai health
