EduRAG

An LLM-based Retrieval-Augmented Generation (RAG) component for education, supporting problem solving, academic literature analysis, and knowledge Q&A.

Features

• Two RAG Modes: SimpleRAG (simple & efficient) and AgenticRAG (intelligent reasoning)
• Multi-LLM Support: OpenAI GPT series, Google Gemini, Ollama local models
• Multiple Document Formats: PDF, DOCX, DOC, TXT, Markdown
• Teacher Persona Customization: Custom teacher name, subject, grade level, teaching style
• Multi-turn Conversation: Context-aware continuous Q&A
• Vector Store Persistence: Avoid repeated embedding, fast knowledge base loading

Installation

pip install edurag

Install optional dependencies:

# Use AgenticRAG (based on LangGraph)
pip install edurag[agentic]

# Use Google Gemini
pip install edurag[gemini]

# Use Ollama local models
pip install edurag[ollama]

# Install all optional dependencies
pip install edurag[all]

Quick Start

Basic Usage

from edurag import SimpleRAG

# Initialize
rag = SimpleRAG(api_key="your-openai-api-key")

# Load documents
rag.load_documents("textbook.pdf")

# Ask questions
answer = rag.ask("What is the main content of this document?")
print(answer)

Custom Teacher Persona

from edurag import SimpleRAG, TeacherProfile

# Create teacher profile
teacher = TeacherProfile(
    name="Mr. Wang",
    subject="High School Physics",
    grade_level="Grade 12",
    teaching_style="Focus on concept understanding, good at explaining abstract principles with real-life examples",
    introduction="20 years of teaching experience, physics competition coach"
)

# Initialize RAG
rag = SimpleRAG(
    api_key="your-openai-api-key",
    teacher_profile=teacher
)

# Load textbooks
rag.load_documents([
    "physics_chapter1.pdf",
    "mechanics_topics.docx"
])

# Ask - AI will respond as Mr. Wang with his teaching style
answer = rag.ask("Why is the acceleration of free fall constant?")

Using Different LLMs

# OpenAI
rag = SimpleRAG(
    api_key="sk-xxx",
    llm_provider="openai",
    llm_model="gpt-4o"
)

# Google Gemini
rag = SimpleRAG(
    api_key="your-google-key",
    llm_provider="gemini",
    llm_model="gemini-pro"
)

# Ollama local model (no API Key required)
rag = SimpleRAG(
    llm_provider="ollama",
    llm_model="llama3"
)

Persistent Vector Store

# First time: auto-save vector store
rag = SimpleRAG(
    api_key="sk-xxx",
    vectorstore_path="./my_knowledge_base"
)
rag.load_documents("./documents/")

# Later: load existing store (skip embedding)
rag = SimpleRAG.from_vectorstore(
    vectorstore_path="./my_knowledge_base",
    api_key="sk-xxx"
)

AgenticRAG (Intelligent Reasoning)

Suitable for complex problems. The Agent autonomously decides whether to retrieve and supports multi-step reasoning.

from edurag import AgenticRAG, TeacherProfile

teacher = TeacherProfile(
    name="Mr. Wang",
    subject="High School Physics",
    grade_level="Grade 12",
    teaching_style="Good at analogies, explains with real-life examples"
)

rag = AgenticRAG(
    api_key="sk-xxx",
    teacher_profile=teacher
)

rag.load_documents(["physics_textbook.pdf"])

# Agent automatically decides whether to retrieve, supports multi-step reasoning
answer = rag.ask("Compare the similarities and differences of Newton's three laws")

# View reasoning process
result = rag.ask_with_steps("Explain the law of conservation of momentum")
print(result["steps"])  # View Agent's reasoning steps
print(result["answer"]) # Final answer
