Harvey

Harvey is an AI company that builds software for legal and professional services work. Its platform, built on large language models adapted to legal tasks, includes an assistant that drafts, summarizes and answers questions with citations, a document vault for reviewing and extracting information from large sets of files, legal research across case law and regulation, and workflows that chain several steps for tasks such as contract analysis, due diligence, compliance reviews and litigation preparation. Firms can ground the system in their own documents and templates, and it integrates with common document management tools and with Microsoft Word. It is used by law firms, corporate legal departments and other professional services firms such as tax and advisory practices.
