Legal AI - Contract Understanding Assistant
A retrieval-based assistant for exploring legal documents through conversational questions, clause extraction and summaries.
Overview & Summary
A retrieval-based assistant for exploring contracts and legal documents through natural-language questions. It uses document chunking, embeddings, FAISS, LangChain and Groq to retrieve relevant context before generating summaries or answers. It is an educational prototype and does not provide legal advice.
The Engineering Challenge
System Architecture & Topology
Strategic Architectural Decisions
Decision 1: Key Trade-off↓
Use retrieval to constrain document questions instead of placing the complete document into every prompt.
Decision 2: Key Trade-off↓
Use FAISS as a lightweight local vector index for the prototype.
Decision 3: Key Trade-off↓
Separate legal information retrieval from legal advice and include an explicit professional-review disclaimer.
Decision 4: Key Trade-off↓
Favor structured prompts for clause extraction and summarization.
