Email that understands legal work
Mattera is an inbox-first legal workspace that helps litigation teams at mid-sized law firms triage their daily work. It reconciles email, documents, and calendar data into a matter-aware system that auto-links emails to cases, predicts actions through AI-powered signals, and enables semantic search across 18,000 legal concepts using the FOLIO legal knowledge graph. Mattera serves employment law, personal injury, and workers' compensation defense firms, with Luna, a voice-driven AI assistant for planning and case triage.

How Mattera works
What are signals in Mattera?
Signals are AI-generated action suggestions — scheduling, tasks, follow-ups, conflict alerts — that surface from your email and documents. They predict what needs attention and improve based on natural language feedback from your team.
What is matter-aware search?
Matter-aware semantic search understands legal terminology (e.g., searching "SROG" finds "Special Interrogatory" documents). It finds information for you, but signals also find you — surfacing what's urgent before you search for it.
How does Luna help litigation teams?
Luna is Mattera's AI assistant accessible through chat and voice. Ask Luna to summarize a 128-page deposition, find all documents related to a motion, draft a reply, or plan your day's priorities across cases.
Built on the FOLIO legal knowledge graph
Mattera is built on the FOLIO legal knowledge graph (Federated Open Legal Information Ontology), an open standard with 18,000+ legal concepts. FOLIO classifies and understands legal documents and matters across discovery, pleadings, court documents, medical records, and expert reports with high accuracy using custom legal embeddings.
From inbox to action in one click
Unlike traditional practice management systems that start with case files, Mattera starts where lawyers spend their day — the inbox. It complements existing tools by adding an intelligence layer that auto-classifies, links, and triages email without requiring migration from Gmail or Outlook.

The legal email problem
Attorneys receive 120+ emails per day and spend 48% of their workday on administrative tasks. 25% of legal malpractice claims stem from administrative errors. 80% of case knowledge is scattered across email inboxes, making critical information hard to find when it matters most.
Mattera reduces average document search time from 2.5 minutes to 4.5 seconds. The legal operations software market is projected to reach $6.4 billion by 2032, growing at 14.5% CAGR, as firms increasingly adopt technology to address these challenges.
Serving California litigation firms
Mattera serves California litigation firms specializing in employment and labor law (FEHA, PAGA, wage and hour disputes), personal injury, and workers' compensation defense. The system works across practice areas, understanding California-specific document types, court filing requirements, and deadline calculations.
