Introduction

Polaris set out to make complex legal and advisory knowledge instantly accessible and trustworthy. Generic AI tools risk inaccurate or ungrounded answers in this domain. Grayphite partnered with Polaris to build a RAG-driven assistant that grounds every response in trusted sources.

Legal and advisory teams needed fast answers from dense, sensitive documents — but generic AI tools risked ungrounded, unverifiable responses.

Objective

Build a secure, RAG-driven assistant that delivers trusted, source-backed legal intelligence:

  • Ground answers in approved documents with retrieval-augmented generation.
  • Provide citations so every response is verifiable.
  • Accelerate research and drafting for advisory teams.
  • Respect strict permissions and data-security requirements.
  • Support collaboration across legal and advisory workflows.
  • Scale reliably across growing document collections.

Problem statement

Legal and advisory work depends on dense, sensitive documents that are slow to search and risky to summarize with generic AI tools that can hallucinate.

Teams needed answers they could trust and verify, with strict controls over what information could be accessed and how.

The solution

We built a RAG-driven assistant that retrieves from approved sources, grounds every answer in citations, and respects enterprise security controls. What we built:

  • A retrieval-augmented generation pipeline over approved legal documents.
  • Source citations on every answer for verifiability and trust.
  • Secure retrieval with role-based access and permission controls.
  • Drafting and research assistance tuned to the legal domain.
  • Collaboration features for advisory and legal workflows.
  • A scalable architecture for growing document collections.

Transformation & key outcomes

Polaris gave teams fast, trustworthy answers grounded in their own documents, with citations that made every response verifiable.

Research and drafting accelerated while security and accuracy were preserved, enabling confident use of AI in a high-stakes domain.

Conclusion

Polaris delivered AI-powered legal collaboration built on RAG — grounding intelligence in trusted sources, accelerating work, and maintaining the security and accuracy the domain demands.

Future impact

Polaris is positioned to expand into deeper document intelligence and workflow automation, broadening coverage across legal, tax, and wealth-planning use cases with secure, retrieval-grounded AI.
