Master the record.
Everything you need to ingest, search, review, and act on a matter's evidence — and to use Sentinel's AI assistant with confidence. User guides, an API reference, security details, and answers, all in one place.
Welcome to the documentation for Sentinel — an enterprise platform for legal compliance monitoring and eDiscovery. Read it top to bottom as a manual, or use the sidebar search (press /) to jump to a topic. Every page has a print link, and a single printable version bundles the whole manual into one document for PDF export.
Ingestion
Upload files, email archives, and media. Sentinel extracts text, runs OCR, deduplicates, and indexes everything automatically.
Search
Keyword, semantic, hybrid, and visual search across a matter's documents and transcripts — find by exact term or by meaning.
Emma, the AI assistant
An assistant grounded in your evidence — searches, drafts answers with verifiable citations, and helps with review, by text or voice.
Document review
A three-pane workspace with coding, tagging, bulk actions, email threading, and predictive coding (TAR/CAL).
Sessions
Record and transcribe depositions, interviews, and meetings with speaker diarization and live AI assistance.
Security & compliance
Per-tenant isolation, data residency in your Azure environment, audit logging, and citation-verified AI output.

Practice modes
Sentinel adapts its interface to your practice. A tenant runs in one of three practice modes — Litigation, Transactional, or Real Estate — which changes the navigation and available features. See Core Concepts → Practice modes.
A note on accuracy. This documentation describes the Sentinel product as built. Some features are practice-mode-specific or role-gated, and a small number of surfaces are still in active development — these are called out where relevant. If something in your environment differs, your administrator may have configured it differently, or you may be on a different practice mode.
