Glean

Glean is a web-based Work AI platform for large enterprises that unifies enterprise search and work automation across disconnected internal tools and data sources.

Key capabilities include:

• Unified enterprise search across 100+ connectors (including Google Workspace, Microsoft 365, Slack, Jira, Confluence, and Salesforce) to find documents, messages, tickets, and people from one interface.
• Permissions-aware retrieval that respects existing access controls, paired with Retrieval-Augmented Generation (RAG) to answer questions with relevant, contextual results.
• AI Assistant and agents that can summarize documents and threads, help create content and updates, and support role-specific workflows through Glean Apps, plus a Prompt Library for reusable prompts.
• Admin and developer tooling such as AI Studio and Knowledge Studio for governance and relevance tuning, and APIs, web SDK, and MCP support to connect company knowledge to other AI tools.

Pricing: Unknown (no public pricing details provided).

What makes it notable is its combination of enterprise-grade security and governance, a graph-based approach to understanding relationships across systems, and an open integration layer (APIs and MCP) designed to power other AI applications while maintaining verification and compliance controls.
