Overview
Glean is an enterprise AI platform that unifies search across all workplace applications—Google Workspace, Slack, Confluence, Salesforce, and 100+ more. Unlike consumer AI assistants, Glean indexes your company's entire knowledge base to deliver personalized, permission-aware answers. The platform has evolved from pure enterprise search into a full Work AI platform with Glean Agents for autonomous task execution, Glean Apps for custom AI workflows, and enterprise-grade security that Fortune 500 companies demand. Founded by ex-Google engineers, it brings Google-quality search to enterprise data.
