Private AI for Law Firms: Secure Document Intelligence That Never Leaves Your Control

Attorney-Client Privilege Meets Artificial Intelligence
Law firms guard information that can make or break cases, careers, and entire companies. Every document that touches a public AI service becomes a liability, a potential breach waiting to show up in discovery.
That's why leading firms now demand Private AI: systems where prompts never leave the network and client data stays exactly where ethics rules require.
The Vault & Desk Model
Zedly separates storage from analysis with a purpose-built architecture. The Vault holds your entire document repository, contracts, briefs, discovery sets, correspondence, encrypted and access-controlled. Nothing gets processed until you explicitly move it to the Active Desk.
The Desk is your working surface. Add the specific documents relevant to your current matter, and only those files become searchable and analyzable. When you're done, clear the Desk. The Vault remains untouched, audit logs intact.
Context Windows Built for Discovery
Legal matters don't fit in 8K tokens. A single deposition transcript can run 500 pages. Zedly's chunking and retrieval system handles documents of any size, pulling the most relevant passages from thousands of pages in seconds.
Ask about a specific clause buried in exhibit 47 of a 200 document production. The system finds it, cites the exact page, and never hallucinates facts that could embarrass you in court.
Legal-Tuned Embeddings
General-purpose AI models stumble on legal terminology. "Motion to compel" and "motion to dismiss" look similar to standard embeddings but carry opposite meanings in practice.
Zedly automatically detects legal documents and routes them through Voyage-law-2, an embedding model trained specifically on case law, contracts, and regulatory filings. Your searches return what you actually need.
Privacy That Satisfies the Bar
Model Rules of Professional Conduct require competence in technology and confidentiality in client communications. Using public AI tools with client data creates risks that many bar associations have already flagged.
Zedly's Private AI runs inference without sending data to third-party model providers. Embeddings stay in your namespace. Conversations aren't used for training. The architecture was designed for regulated industries from day one.
Organization-Level Controls
Managing partners need visibility. Zedly provides organization-wide storage pools, per-seat quotas, and usage dashboards. Know exactly how much each practice group consumes without micromanaging individual attorneys.
Set ingestion limits so a first-year associate can't accidentally process a 50GB document dump overnight. Approve large jobs before they run. Keep costs predictable and audit trails complete.
From Brief Research to Due Diligence
Draft a motion and instantly search your precedent library for supporting language. Upload an M&A data room and surface red flags in hours instead of weeks. Review contracts against your clause library and flag deviations automatically.
The same secure infrastructure handles research, review, and analysis without switching tools or compromising client confidence.
Start With One Matter
Most firms pilot Zedly on a single case. Upload the relevant documents, add them to the Desk, and start asking questions. Within days, the ROI becomes obvious: faster research, better organized files, and zero data leakage concerns.
Your clients trust you with their most sensitive information. Private AI is how you honor that trust while still moving at the speed modern practice demands.
