What Glean does

Glean provides a Work AI platform that connects knowledge, systems, and context across an enterprise to enable AI to function effectively. It offers AI-powered enterprise search, an AI assistant, and a platform for building and deploying AI agents. The platform is designed for enterprise use, focusing on security, explainability, and permission-awareness. Glean aims to reduce token usage and costs for AI models by providing pre-connected enterprise context and an agent harness that optimizes model usage. It integrates with over 275 applications and offers open APIs for custom connectors and actions, allowing businesses to build context-aware AI applications.

Products

• Glean Agent HarnessA system for routing work across 30+ models, including Claude, Gemini, OpenAI, and NVIDIA, with no provider lock-in. It uses a coding harness for execution, manages context efficiently, and employs trace learning to improve workflows over time.
• Glean WaldoGlean’s agentic search model that reduces latency by 50% and tokens by 25%, reserving advanced models for tasks that need them.
• Glean Enterprise ContextA platform that builds connectors, indexes data, creates an Enterprise Graph, and learns processes to provide full context for automating work.
• Glean ProtectEnsures data safety and agent reliability by running in a single-tenant cloud, safeguarding sensitive content, enforcing strict permissions, and intelligently validating agent actions.
• Glean AgentsAllows users to give agents tasks, which then use context and reasoning to automate work. Glean enforces agent behavior at runtime for reliability and accuracy.
• Glean SearchAn AI-powered enterprise search that helps users find information across all company data sources.
• Glean AssistantA personalized AI expert that helps automate work using natural language and offers flexible LLM choice.
• Glean AI GatewayAn enterprise AI control plane for observability, model hub, and enterprise graph. It allows access to 30+ frontier and open-source models, tracks token consumption, and enforces access controls.
• Glean Enterprise GraphUnderstands how a company works by capturing relationships across people, projects, teams, and processes, providing deep organizational knowledge for AI.
