Glean, founded in 2019, addresses a different problem than the notes and meeting tools elsewhere in this category: enterprise search across a company's actual scattered internal systems, Slack, Confluence, SharePoint, Salesforce, and dozens more, letting an employee search once and find relevant information regardless of which specific tool it actually lives in.
That horizontal, cross-system scope extends past search into AI agents that take action across those same connected systems, permission-aware so an employee only ever sees content they're already authorized to access, rather than a centralized knowledge base requiring content to be manually migrated or re-entered into Glean itself.
There's no free tier; Glean sells through enterprise contracts. For a larger organization whose institutional knowledge is genuinely scattered across dozens of disconnected internal tools, Glean's cross-system, permission-aware search addresses that fragmentation directly, a different problem than a single, centralized knowledge base tool solves.
