Best for
Companies of 200 plus seats drowning in scattered internal knowledge

Glean attacks the oldest problem in knowledge work: the answer exists somewhere in Slack, Confluence, Drive, Jira, or email, and nobody can find it. Its search index spans the whole app stack while strictly honouring each user’s existing permissions, and the assistant on top gives employees a ChatGPT-like experience that actually knows internal context, who owns a project, what the leave policy says, where the latest deck lives. Companies that deploy it well report the kind of time savings that make the CFO stop asking questions.
The catch is that Glean is an enterprise platform with enterprise economics, quote-based pricing that only makes sense at hundreds of seats, and a rollout that requires IT commitment to connect every data source. Buy it as an infrastructure decision, not an app purchase. For organisations at that scale, it has become the reference product in enterprise AI search.
