Juristo AI:
AI Legal Research Platform
A SaaS-based AI legal research and document automation platform enabling case law search, judgment summarization, legal drafting, and voice-based legal assistance.
The
Challenge
Legal research is dense, precedent-heavy, and unforgiving of inaccuracy. Juristo AI needed an AI platform that could search case law, summarize lengthy judgments, generate legal drafts, and provide voice-based assistance — without the hallucination risk that makes generic LLM tools unusable for legal work.
The platform also needed to coordinate multiple specialized AI tasks — retrieval, summarization, reasoning, and drafting — in a way that stayed context-aware across a single research session, while handling the security and compliance expectations that come with legal documents and court records.
Furthermore, processing massive volumes of dense, citation-heavy legal text inherently drives up both API costs and latency. The business required an architecture that could intelligently route queries and chunk documents to maintain extremely fast response times without incurring exorbitant computational expenses on every search.

The
Solution
Toadster designed a multi-agent AI architecture using LangChain and LangGraph, coordinating specialized agents for legal research and drafting rather than relying on a single monolithic prompt. Judgment retrieval, summarization, and context-aware legal reasoning were implemented across multiple LLMs — OpenAI, Cohere, Anthropic, and Gemini — chosen for the strengths each model brought to specific legal reasoning tasks.
REST APIs built on Django REST handled real-time data processing, user interactions, and orchestration between agents, while voice-based legal assistance was integrated through dedicated speech-to-text and text-to-speech pipelines, letting lawyers interact with the platform hands-free during research.
