Ask across firm knowledge
Find clauses, obligations, definitions, amendments, and precedent across authorized matter documents without moving those documents to an external AI provider.
↗PRIVATE AI INFRASTRUCTURE FOR LAW FIRMS
Use AI on confidential legal work.
Keep the data inside your firm.
LexDeploy designs, deploys, and manages private AI environments for legal practices that require data sovereignty, matter isolation, and verifiable answers.

SCROLL TO EXPLORE↓
01 / THE PROBLEM
Cloud AI can be excellent.
For some legal matters, sending the data out is the problem.
Client documents may carry confidentiality obligations, contractual restrictions, internal AI policy requirements, or simply a risk profile that makes external processing undesirable.
LexDeploy gives the firm another option: run the AI, retrieval system, document index, and governance controls on infrastructure the firm controls.
WHAT LAWYERS GET
A useful legal assistant should not ask you to choose between capability and control.
Verify every answer
Answers are grounded in retrieved source material and linked back to deterministic document, page, section, and chunk provenance.
↗Respect ethical walls
Identity and matter authorization are applied before retrieval, so semantic search cannot cross into matters the user is not permitted to access.
↗02 / ARCHITECTURE
The intelligence stays close to the evidence.
A model-agnostic private RAG platform built around access control, retrieval quality, provenance, and operational isolation.

MODEL-AGNOSTIC
The generation model can change as stronger local models emerge. The firm's knowledge and governance layer remain.
PROVENANCE FIRST
Citation identifiers are generated by the application from stored document metadata—not invented by the model.
RETRIEVAL BEFORE GENERATION
The system narrows the evidence first, then asks the model to reason over the authorized passages that matter.
03 / SECURITY MODEL
Data sovereignty does not mean giving up maintainability.
For most firms, LexDeploy uses controlled remote administration that is separated from the legal-data path. We can monitor health, restart services, and deploy tested releases without routinely exposing document content, prompts, or answers.
TWO DEPLOYMENT MODES
RECOMMENDEDManaged Sovereign
Client data stays in the firm's environment while LexDeploy receives restricted, audited administrative access for operations.
- Firm-controlled VPN or secure management channel
- MFA and restricted privileged commands
- Sanitized operational monitoring
- Tested model/application upgrades and rollback
- Break-glass access only when explicitly needed
MAXIMUM ISOLATIONFully Isolated
No persistent remote management path and no external telemetry. Designed for environments where administrative isolation is itself a requirement.
- No persistent internet connection required
- Signed offline release packages
- Customer IT or scheduled on-site maintenance
- Local-only monitoring and audit trail
- Scoped separately due to operating model

Start with your workload, not our sales pitch.
We build a controlled proof of concept on existing or temporary infrastructure, evaluate representative legal tasks, and use the results to determine whether production deployment makes sense.

No per-query or token charges for local inference. The firm owns its production hardware.
