Glean

Glean is an enterprise AI search and assistant platform that connects to an organization's entire software stack — including Slack, Google Drive, Confluence, GitHub, Salesforce, and dozens more — and provides a unified search experience across all company knowledge. Its AI assistant answers questions grounded in internal documents, past conversations, and company data, with citations for every response. Glean also surfaces relevant information proactively and supports custom AI agents. It is used by large enterprises and fast-growing companies that need to make organizational knowledge accessible and reduce time spent searching for information across fragmented tools.
