How does Glean compare with the alternatives?
A company that runs mostly on Microsoft 365 starts with Copilot, and one spread across Slack, Google, Atlassian, and a CRM weighs Glean. Microsoft lists Microsoft 365 Copilot at US$30 per user per month paid yearly and grounds it in Microsoft Graph plus 100+ connectors. Glean publishes no price and indexes 275+ apps outside any one suite.
Choose Notion AI when Notion holds most answers, and Glean when knowledge spreads across many systems, including on-premises ones Glean reaches through push connectors. Notion AI searches the Notion workspace and its connected apps within each user's permissions; Glean indexes 275+ sources. GILD's search for a head-to-head test of the two on mixed apps found only vendor-written comparisons, so run both on your own questions.
A company whose answers live mostly in Jira and Confluence tests Rovo first, and one spread across many systems weighs Glean. Rovo, Atlassian's AI layer across Confluence and Jira, comes with paid Confluence and Jira Cloud plans at no extra charge and searches Atlassian apps plus 56 listed connectors. Glean indexes 275+ apps, Confluence among them, on its own license.
Choose Glean when most questions need internal sources, and Perplexity when they start on the web. Perplexity Enterprise starts with cited web research and adds company files; Glean starts with company apps and their permissions.
