SWIRL AI Legal Search
Private AI-Powered Search for Law Firms
Now available in the Azure Marketplace 🔗
The Legal Information Crisis
Data Sprawl
Legal work product scattered across iManage, NetDocuments, SharePoint, email, and external databases. Lawyers spend hours searching across disconnected systems.
Compliance Risk
Generic AI tools create hallucination risk and regulatory exposure. Law firms face sanctions for unreliable AI-generated citations and work product.
Permission Chaos
Existing tools either ignore security boundaries or require expensive data migration into vendor-controlled indices that firms don't trust.
No Development Team
Law firms don't typically develop internal solutions with cost/complexity of LLMs. They haven't used AI internally as a result - yet. ABA 2024 AI TechReport 🔗
Pressure to Adopt AI
Law firms and legal departments are under huge pressure to start leveraging AI and reducing costs. Status quo isn't a viable option.
Current Legal AI Solutions Fall Short
Legacy Federated Search
Tools like Autonomy, Verity and TR Legal Search Connect lack AI capabilities, deliver poor result quality, and require extensive IT overhead to maintain - while strugging with modern data formats and lacking semantic understanding crucial for legal nuances.
What is the Future of Search 🔗
"Agentic Attorney" Products
Solutions like DeepJudge require months of data curation and bulk ingestion into third-party systems. Firms tell us: "Nobody likes indexing into DeepJudge" due to security concerns and high costs.
Generic GenAI Assistants
ChatGPT and general tools lack legal system integration, permission awareness, and the reliability standards required for professional legal work. Professionals, including law firms, expect to adopt GenAI via trusted platforms and vendors, viewing it as adriver of change. TR Future of Professionals 🔗
Federated AI Search Built for Legal
SWIRL acts as a neutral layer, feeding any AI assistant (e.g., Copilot, ChatGPT) with trusted, permissioned results from existing applications, data platforms and information services.
Federated Querying
SWIRL queries each repository via APIs, respecting existing permissions. No curation, ingestion or indexing is required. No user ever sees anything they aren't already authorized to see.
Private Deployment
Connects to iManage, M365, custom SharePoint Collections, BetterRegulation.com and many more.
Deploy securely in your Azure tenant in hours via Marketplace with OAuth2/SSO.
AI Re-Ranking
The results returned by each source are re-ranked using your firm's preferred LLM (OpenAI, Azure OpenAI, Anthropic, 20+ more) to surface the most relevant answers in real time.
Integration & AI Assistant
Works standalone or integrates with Microsoft 365 Copilot, ChatGPT or custom UIs as your secure RAG layer. Built-in MCP support for workflow systems like CREW.AI, N8N and Power Automate.
How Lawyers Search Today vs. With SWIRL Legal Search
Today: Patchwork Search Across Systems
Currently, legal professionals waste valuable time navigating a fragmented digital landscape:
  • Lawyers search each system separately, whether it's internal documents or external research.
  • Time is wasted jumping between iManage, NetDocuments, M365, email, and various web tools.
  • It's hard to know if you've found everything relevant to a case, leading to uncertainty.
With SWIRL: One Secure Search for All Your Firm’s Knowledge
SWIRL Legal Search transforms this by providing a single point of access:
  • Single search across matters, documents, emails, and external legal research.
  • Uses your existing systems and permissions—no data copying or migration needed.
  • AI intelligently surfaces and analyzes the most relevant content for each matter, enhancing discovery.
