Glean

Enterprise AI grounded in your company's own knowledge

Permission-aware enterprise search

Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.

Agent builder and orchestration

Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.

Model routing and AI gateway

Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.

Grounded content and analysis

Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.

Strengths & Pros

+One platform covers search, assistant, and agents instead of three separate vendors
+Model routing and token efficiency directly reduce the cost per AI query at scale
+275+ pre-built connectors shorten integration work considerably
