Legal RAG Engine with Authority Weighting
Ask legal research questions and get answers grounded in your indexed documents. A-tier binding authorities score 3x, B-tier persuasive 1.5x, C-tier secondary 0.8x — so the AI cites what matters most.
Your data lives on someone else's server
The Legal Research Lab is the answer
Every document you upload, every query you make, every draft you write gets stored on servers you don't control. Cloud tools mine your work for training data, sell usage analytics, and expose you to breaches. Offline tools run entirely in your browser. Your files never leave your machine.
The Legal Research Lab is a single-file lab with 19 tools that runs entirely in your browser. The Legal Research Lab is a self-contained, browser-based legal research environment delivered as a single HTML file. It runs entirely offline with local AI via Ollama, meaning your case files, briefs, and privileged documents never leave your machine. Index legal documents with tiered authority weighting (binding, persuasive, secondary), query them with RAG retrieval, build concept maps linking cases to statutes, draft memos with integrated citations, and manage entire cases from timeline to trial — all without an internet connection or a subscription.

Local RAG engine with authority-weighted retrieval, case law management, risk matrices, drafting tools, and a Nexus concept graph — all in a single HTML file that never phones home.
Is my data safe with The Legal Research Lab?
Yes. The Legal Research Lab is a single HTML file. It never connects to any server. Your data stays in your browser's local storage on your device.
