How Olatunde Success and the Citizens’ Gavel team shipped Podus AI, an AI legal assistant trained on Nigerian and UK law, across web, mobile, and WhatsApp, and what 6,500+ real legal interventions taught the team.
PODUS started with a blunt observation: most Nigerians who need a lawyer never get one. Cost, distance, and distrust keep people out of the legal system entirely. At Citizens’ Gavel we set out to close that gap with software, and my job as full-stack lead was to make the ecosystem real: podus.org, chat.podus.ai, and appointment.podus.ai, with React/TypeScript on the web, React Native on mobile, and NestJS + PostgreSQL underneath.
Meet users on the channel they already have
The single highest-leverage decision we made was shipping Podus AI on WhatsApp, not just on our own apps. A farmer in Oyo State is not going to download a legal app on a 2GB phone, but WhatsApp is already there. The same NestJS backend serves web, mobile, and WhatsApp channels through one conversation API, so improvements land everywhere at once.
An AI assistant in a domain where wrong answers hurt
Scope honestly: Podus AI is trained on Nigerian and UK law and is explicit about what it does not know.
Escalate to humans: the assistant is a front door, not a replacement. Matchmaking routes real cases to real lawyers.
Log for accountability: every intervention is traceable, which is how we can say with confidence the platform has delivered 6,500+ legal interventions for 35,000+ users.
Confidentiality is an architecture, not a promise
Conversations between clients and lawyers are among the most sensitive data a platform can hold. We treated confidentiality as a first-class architectural constraint: access controls at the database level, real-time channels over authenticated WebSockets, Redis caching that never holds sensitive payloads longer than needed, and code review specifically focused on data-handling paths. Trust is the product; the features are just how it ships.
What I would tell anyone building civic tech in Africa
Build for the infrastructure people actually have, keep humans in the loop where stakes are high, and measure outcomes, not signups. 35,000 users is a nice number; 6,500 people who got real legal help is the number that matters.
