Python API

from readanybook import CheatSheetPipeline, Settings

# Initialize pipeline
settings = Settings()
pipeline = CheatSheetPipeline(settings)

# Process document
pipeline.ingest("textbook.pdf")
pipeline.index(collection_name="textbook")

# Generate cheat sheet
content = pipeline.generate_content()
cheat_sheet = pipeline.build(content, "output/cheatsheet.pdf")

print(f"Generated: {cheat_sheet.pdf_path}")

Quick Start (One-Liner)

from readanybook import build_cheatsheet

# Generate a cheat sheet with a single function call
output = build_cheatsheet(
    "textbook.pdf",
    llm_backend="huggingface",      # or "ollama" for local
    llm_model="Qwen/Qwen2.5-1.5B-Instruct",
    output_format="markdown",        # "latex", "markdown", or "both"
    in_memory=True                   # Required for Kaggle/Colab
)

REST API

# Start the API server
uvicorn readanybook.api:app --host 0.0.0.0 --port 8000

# Upload a document
curl -X POST "http://localhost:8000/upload" \
  -F "file=@document.pdf" \
  -F "collection_name=my_docs"

# Generate cheat sheet
curl -X POST "http://localhost:8000/generate" \
  -H "Content-Type: application/json" \
  -d '{"collection_name": "my_docs", "title": "My Cheat Sheet"}'

Configuration

Create a config.yaml file or use environment variables:

# Embedding model
embedding:
  model_name: "BAAI/bge-base-en-v1.5"
  device: "cuda"

# Vector store
vectordb:
  store_type: "chroma"
  persist_directory: "./data/chroma"

# Retrieval
retrieval:
  mode: "hybrid"
  top_k: 15
  
# LaTeX output
latex:
  columns: 2
  font_size: 10
  paper_size: "a4paper"

Configuration Profiles

Use built-in profiles for different document types:

# For technical books
read-any-book build book.pdf --profile technical_book

# For math papers
read-any-book build paper.pdf --profile math_paper

# For non-technical books
read-any-book build novel.pdf --profile nontechnical_book

Architecture

ReadAnyBook follows a modular pipeline architecture with clear separation between ingestion, retrieval, and generation layers.

Design Principles

• Hexagonal Architecture: Domain services isolated from external adapters
• Configuration-Driven: All behavior controlled via Pydantic settings
• Pluggable Backends: LLM, vector store, and embedding model abstractions
• Observability: Structured logging and tracing throughout

📄 Full documentation: See docs/architecture.pdf for the complete software architecture document.

📓 Kaggle Experiment

We tested ReadAnyBook on Kaggle with Hull's "Options, Futures, and Other Derivatives" (902 pages) using a T4 GPU:

Model	Backend	Time	Notes
microsoft/phi-2	HuggingFace	~15 min	Fast, basic quality
Qwen/Qwen2.5-1.5B-Instruct	HuggingFace	~20 min	Better reasoning
meta-llama/Llama-3.2-3B-Instruct	HuggingFace	~30 min	Best quality (needs HF token)

Note: Use latex_only=True on Kaggle/Colab since pdflatex is not available.

Examples

See the examples directory for:

• 📓 readanybook_demo.ipynb - Interactive notebook tutorial
• Processing academic papers
• Creating ML textbook cheat sheets
• Custom template usage
• API integration examples

Testing

ReadAnyBook has comprehensive test coverage with 101 tests across three levels:

# Run all tests
pytest tests/

# Run specific test suites
pytest tests/unit/           # 81 unit tests
pytest tests/integration/    # 6 integration tests
pytest tests/e2e/           # 14 e2e tests (uses Project Gutenberg books)

Test Coverage:

• Unit Tests: Core modules (chunking, ingestion, indexing, retrieval), summarization passes, experiment tracking, regression suite
• Integration Tests: Pipeline flows, retrieval service, orchestrator integration
• E2E Tests: Full pipeline with real books from Project Gutenberg (Art of War, Flatland, Metamorphosis)
