LegalMemory

An open-source, on-prem knowledge index for law firms. LegalMemory builds a continuously synced shadow index over your document estate, without changing a single source file, and exposes it to AI tools through MCP, with your firm's permissions enforced on every query.

Connect your sources

SharePoint, OneDrive, Google Drive, Clio, local folders and more. Read-only, with source permissions mirrored into the index. See the connector guides.

Structured, not just embedded

An insertion pipeline classifies every document into a matter, links versions and related documents, extracts typed metadata and decision rationale, then indexes it for hybrid retrieval. See the insertion pipeline.

Permissions first

Identity → project grants → mirrored source ACLs → search scope. Deny wins, unknown ACLs fail closed, and every query is filtered before ranking. See access control.

Open to your tools

Identity-bound MCP tools for search, matters, decisions and billing, plus a REST API. Every call runs under the caller’s own permissions. See external access.
