What is Glean and what is it used for?
Glean is an AI platform for work that searches a company's connected tools and answers employees' questions from that content. It started as enterprise search in 2019 and now includes an AI assistant and agents.
Search finds documents, messages, tickets and conversations in one place, and each person sees only what they already have permission to access: connectors bring in the permission map of each source. The vendor lists more than 250 ready-made connectors, while older pages mention more than 100.
The Assistant answers with citations and drafts text. Agents run multi-step tasks across tools and can be created by describing the desired result in natural language. Teams that want to integrate on their own have custom connectors, an indexing SDK, MCP servers and OpenAPI-based actions.
Glean's documentation states that the product supports decision-makers and does not replace the person in high-risk areas such as hiring.
