01
Ground the model
We built a retrieval-augmented (RAG) pipeline over the legal corpus so the model answers from retrieved law, not from memory — the difference between a useful tool and a liability.

Lexa
Pakistan's first AI legal chatbot, grounded in real law.
An AI assistant that turns plain-language questions into clear, sourced legal guidance — built on a retrieval pipeline so answers stay anchored to actual statutes, not model hallucinations.

The challenge
What needed to be true
Legal help in Pakistan is expensive, slow, and intimidating for ordinary people. Most never speak to a lawyer until a problem has already become a crisis, and generic chatbots are worse than useless on law — they invent confident-sounding answers with no basis in statute.
The goal was a public-facing assistant people could actually trust: conversational enough for a non-lawyer, but anchored to the real legal corpus so every answer could be traced back to a source.
How we approached it
The approach, step by step.
02
Engineer the conversation
Heavy prompt engineering and guardrails keep responses scoped, cite their basis, and decline gracefully when a question needs a human lawyer.
03
Ship a public product
A fast Next.js front end made the assistant accessible to anyone with a browser — no app install, no signup wall between a person and a first answer.
