Glean

Overview

Glean indexes the tools a large company already runs — Slack, Drive, Confluence, Jira, SharePoint, GitHub, Salesforce and dozens more — and puts a permission-aware search and answer layer over the top, with an agent-building framework alongside it. The pitch is not that it stores knowledge, but that it finds knowledge you already have and never manage to locate. In organisations past a certain size that problem is real and expensive, and Glean is the most credible product addressing it; the permissions model, which ensures answers never leak documents a user could not otherwise open, is the hard engineering that competitors underestimate. It is unambiguously an enterprise purchase. There is no published pricing and no self-serve entry — you go through a demo and a sales cycle. Value scales with the messiness of your data estate, which means a well-organised 50-person company will wonder what it paid for. And its answers are only as good as the documents beneath them: Glean surfaces your outdated wiki page faithfully, it does not fix it.
