Build an in-house legal platform with the Relex SDK

Build your interface and workflows on existing legal matter and confidentiality foundations.

What you reuse

The SDK connects your application to Relex matters, parties, knowledge, ontology, drafts and billing APIs. Its Node.js, Python and Java bindings share the native protection implementation: seal identity fields and redact documents in your process before upload.

What you still build

Your interface, sign-in experience, roles, workflow rules, deployment and professional review. Preserve tenant authorization and keep the PII password out of the server and agent. Billing or export can require a deliberate, limited identity disclosure. This is an application foundation, not a ready-made compliant firm.

SDK, MCP or Marketplace?

Use the SDK to build a portal or in-house platform. Use MCP to connect a supported assistant to the same saved matter. Use Marketplace to publish an eligible firm profile or request professional help. The platform example runs against a mock by default; verify package access, service permissions and live behavior before launch.
