Original: # I Built a Legal OS for a Zimbabwean Law Firm — Here's What AI-Assisted Legal Research Actually Looks Like
Short summary
A developer built MutemoOS, an AI-assisted legal research system for a Zimbabwean law firm, addressing jurisdiction-specific challenges that generic RAG pipelines miss — including scattered case law, colloquial-to-statutory term mapping, and dual legal systems. The system uses a two-stage Claude synthesis pipeline (Haiku for grounding checks, Sonnet for constrained synthesis) with explicit source-sufficiency badges to prevent hallucinated citations. A two-layer fallback combining FTS and Zimbabwe-specific query expansion handles terminology gaps where embedding models fail on local legal concepts like lobola and small houses.
- •Built MutemoOS with FastAPI, ChromaDB, and Claude for Zimbabwe-specific legal research replacing a 118-matter notepad system
- •Two-stage synthesis pipeline (Haiku ground-check + Sonnet constrained synthesis) eliminates hallucinated citations with visible source-sufficiency badges
- •Two-layer fallback (FTS + Claude query expansion) solves embedding model failures on Zimbabwean colloquial-to-statutory term mappings
Generated with AI, which can make mistakes.
