Why it exists
Legal teams manage contracts across email threads, shared drives, and static templates with no structural verification layer. Existing AI contract tools either answer with confident-sounding guesses that aren't traceable to the source document, or bolt AI onto a workflow that doesn't talk to the firm's actual infrastructure, DMS, calendar, e-signature, org hierarchy. Teams need answers that point to a specific line, not a plausible one.
What it does
LexVault is a full contract lifecycle platform: draft, review, redline, sign, collaborate, wrapped around an AI layer where every claim is server-side validated against exact line ranges in the source document before it reaches the user.
On top of that: DAG-based approval workflows with human-in-the-loop gates, DMS integrations (iManage, NetDocuments), calendar sync, and multi-tenant org management with seat-based billing.
This is an in-house product we sell and operate, not a one-off client build.
In production
- Every AI citation is validated server-side against exact document line ranges before it's shown, failed citations return a fallback, never a fabricated reference
- 20+ database tables span contracts, workflows, vaults, and a 365-day compliance audit trail
- Runs as a 4-app system (product app, marketing site, admin panel, background worker) in production on AWS
