Harvey AI
Harvey leverages advanced generative AI, built on customized versions of OpenAI's GPT models (including GPT-4), fine-tuned with legal data, and has expanded to integrate foundation models from Anthropic and Google. It assists lawyers and professional services firms with tasks such as contract analysis, due diligence, litigation support, regulatory compliance research, document summarization, comparison, and drafting. It aims to augment legal professionals, increasing efficiency and allowing focus on higher-value strategic work. It can be further trained on a firm's own data and templates for more specialized outputs. Harvey has introduced a Workflow Builder feature, enabling firms to create tailored AI agents adaptable to specific legal workflows. As of December 2025, Harvey serves 337 legal clients across 53 countries, including major law firms and corporate legal departments.
