Usage

Command Line

# Generate a cheat sheet from a PDF
read-any-book build document.pdf -o cheatsheet.pdf

# Use a specific profile
read-any-book build document.pdf --profile math_paper

# Index a document
read-any-book index document.pdf --collection my_collection

read-any-book search "gradient descent" --collection my_collection

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}")

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"

# LLM settings
llm:
  backend: "ollama"
  model_name: "llama3:8b"

# 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
