How LawLingo works
LawLingo answers California tenant-rights questions from real statutes — in plain language, in your language. This page explains how to use it and what happens behind the scenes.
What it does
Two ways to use it
One RAG engine, two entry points — pick a curated legal question, or bring your own document.
Legal Q&A — multilingual
Ask about deposits, repairs, eviction, rent caps and more across 11 California Civil Code sections. Answers arrive in your language with exact citations.
Chat with your documents
Upload any text-based PDF and ask about it. Answers are grounded only in your file, quoting the exact source sentence — works for any kind of document.
Usage
How to use it
- 1
Ask in your own language
Type your question the way you'd say it — English, 한국어, or Español. No legal jargon needed. LawLingo detects the language and replies in it.
- 2
Read the answer & citations
Each answer cites the exact Civil Code section (e.g. §1950.5(h)(1)) and quotes the original statutory text in English so you can verify it.
- 3
Explore demos for free
The Demo Gallery replays real Q&A instantly at no cost. Live questions are limited to 3 per day to keep the public demo running.
- 4
Chat with your own PDF
Upload any document — contract, policy, manual — and ask about it. Answers come only from your file, quoting the exact source sentence.
Under the hood
How the system works
LawLingo uses Retrieval-Augmented Generation (RAG). Instead of trusting a language model's memory, it looks up the real statute text first, then writes the answer from it.
1 · Retrieve
Your question is embedded and matched against a vector database of 85 chunks from 11 California Civil Code sections. The most relevant passages are pulled in. Non-English questions are translated to English for this search step only.
2 · Ground
GPT-4o is given only those retrieved passages and instructed to answer from them alone — not from general training data. This is what keeps answers tied to the actual law.
3 · Cite
Every claim names its section number and quotes the original English text. Citations stay in English even when the rest of the answer is in another language.
4 · Refuse
If the retrieved sections don't contain the answer, LawLingo says "Not found in the provided sections" instead of inventing law. No hallucinated statutes.
Languages
Ask in your language
The model detects your question's language and answers in the same one. Today the demo showcases English, 한국어, and Español.
Section numbers and quoted statutory text always stay in English — so a lawyer or official can verify the source, whatever language you asked in.
Good to know
A few practical notes
Demos are free
The Demo Gallery replays cached answers with no API cost or limit.
Live limit: 3/day
Live questions are capped per visitor to keep the public demo affordable.
Text-based PDFs
Document chat needs selectable text — scanned image-only PDFs won't extract.
Not legal advice
LawLingo provides statutory information for orientation, not legal counsel.
