Glean

Glean connects to company apps and documents to let employees search, ask questions, and get AI-generated answers from all their work data.

Description

Glean's Work AI platform ingests enterprise data through 100+ native connectors to construct a unified knowledge graph that powers three core modules: hybrid search with custom language models, conversational AI assistants for content generation and analysis, and autonomous agents that execute multi-step workflows via an agentic reasoning engine. The platform processes queries through real-time permission filtering and contextual retrieval, delivering responses through web interfaces, Slack/Teams integrations, browser extensions, and REST APIs that maintain enterprise security controls. Cross-functional teams deploy Glean through centralized instances that sync with existing SaaS applications, while developers extend functionality through SDKs and custom plugins that integrate the knowledge graph with specialized business processes and automation workflows.

What Problem Does Glean Solve?

Important answers hide across dozens of internal tools—Slack, SharePoint, email, Confluence—forcing employees to waste time tracking them down. This constant searching slows productivity and decision-making across every department. Glean connects to all company data sources and lets employees find answers instantly through AI-powered search, eliminating the need to dig through multiple apps.
