Alexus Legal AI

A warm, conversational AI legal companion for Filipinos: explains Philippine law in plain language, relates it to your situation and ends with concrete next steps.

Sole engineer · 2026 · Designed, built and deployed by Alexus Karl Joaquin.

What I built

• Streaming chat on the Next.js App Router with a system prompt engineered for empathy: acknowledge the person's situation, tie answers to their specific case, explain statutes simply, always finish with actionable steps.
• Covers the Constitution, Civil Code, Revised Penal Code, Labor Code, Family Code, property, tax, corporate and procedural law, with a clear "not legal advice" boundary.
• Per-user conversation history persisted in PostgreSQL (conversations and messages APIs, auto-initialised schema), plus image upload for document analysis.
• Mobile-first glass UI with popular-question shortcuts and a PWA manifest so it installs like a native app.
