Find answers across company tools, pick the right sources, and build agents that do the digging for you.
Start: What Glean is and where things liveAbout Glean
Glean is AI search and an Assistant over your company's connected apps, like docs, tickets and chat. It answers questions with citations and only uses content you can already open, so colleagues may get different answers. You can also build agents, keep work in Projects, run Deep Research, and use Glean in Slack and the browser. Admins govern it from the Admin console.
Best for: People at companies that use Glean to find answers across many work tools, and the admins who set its rules.
Good for
- Finding the right doc or answer across many tools from one box
- Cited answers that follow each person's permissions
- Agents that run from a chat, a form, a schedule or new content like a ticket
- Deep Research reports from company sources and the web
Where people slip
- Trusting an answer without opening the citation and checking its date
- Posting a private Slack answer to a channel when it used restricted sources
- Letting an agent's write steps run without confirmation before you've tested it
- Picking the wrong Sources setting for the question
What is Glean used for?
Finding information spread across work apps. You ask in Chat or Search, and Glean answers with citations from your connected tools. It mirrors the permissions in those apps, so it only uses what you can already open.
Why does my colleague get a different answer in Glean?
Glean mirrors the permissions in your connected apps and personalizes results. If you can open different documents, you can get different answers. Check the citations to see which sources it used.
Can Glean agents take actions?
Yes, through write tools. By default each write step asks the user to confirm. Admins can make a tool eligible to run without confirmation, and builders then turn that on per step. Test an agent before you remove confirmation.
What replaced Glean Collections?
Projects. Collections moved to Projects automatically, keeping their content and access. Projects are private by default, and you can share them with people as Viewer or Editor.
