Glean
EnterpriseEnterprise AI search and assistant that indexes every app in your company for instant answers
What is Glean?
Glean is an enterprise AI work assistant that indexes and connects every app your company uses — Slack, Google Drive, Microsoft 365, Notion, Confluence, Jira, GitHub, Salesforce, Zendesk, and 100+ others — and turns that entire universe of internal knowledge into a single AI-powered search and chat interface. Where general assistants like Notion AI or Slack AI are limited to their own platforms, Glean unifies cross-tool search with permission-aware retrieval: employees only see content they're authorized to access. Core capabilities include semantic search across all connected apps, an enterprise AI chat assistant that answers questions with citations from your internal docs, a no-code app builder for creating custom AI assistants, knowledge graphs that understand people, topics, and projects across the company, and agentic workflows that can complete multi-step tasks. Glean is built specifically for mid-market and enterprise deployments — there is no free tier or self-serve plan. Pricing is custom and quoted per seat based on deployment size, typically starting in the low five figures annually for mid-market teams and scaling into six or seven figures for large enterprises. Glean is a leader in the enterprise AI search category alongside products like Microsoft Copilot for Microsoft 365 and is used by companies like Reddit, Pinterest, Duolingo, and Databricks. If your organization wastes hours hunting for internal information across dozens of apps, Glean is usually the first enterprise AI purchase that pays for itself.

FAQ
How much does Glean cost?
Glean is enterprise-only with custom pricing quoted per seat. Mid-market deployments (50–200 employees) typically start in the low five figures per year, and larger enterprises pay into six or seven figures depending on seat count, connectors, and deployment model. There is no self-serve plan — buyers book a demo with Glean's sales team for a custom quote.
What apps does Glean connect to?
Glean supports 100+ enterprise connectors including Slack, Google Drive, Microsoft 365, Notion, Confluence, Jira, GitHub, Salesforce, Zendesk, HubSpot, ServiceNow, Asana, Linear, Dropbox, Box, Outlook, Teams, SharePoint, and many more. New connectors ship regularly. For custom internal apps, Glean offers an SDK and REST API to build your own.
How is Glean different from Microsoft Copilot?
Microsoft Copilot for Microsoft 365 is deeply integrated with the Microsoft stack (Word, Excel, Outlook, Teams, SharePoint). Glean is platform-agnostic and connects Microsoft tools alongside Slack, Google Drive, Jira, GitHub, Notion, Salesforce, and 100+ others. If your company runs 80%+ on Microsoft, Copilot is a natural fit. If you're multi-vendor with SaaS sprawl, Glean is typically the better enterprise search layer.
Is Glean permission-aware?
Yes, and this is one of its most important features. Glean respects the native permissions of every connected app — if you don't have access to a Google Doc, Slack channel, or Jira ticket in the source app, Glean won't surface it in search or chat. This makes Glean safe to deploy company-wide without accidentally exposing sensitive HR, legal, or finance content to the wrong employees.
Can Glean build custom AI apps?
Yes. Glean includes a no-code AI app builder that lets teams create custom assistants for specific workflows — for example, an engineering onboarding bot trained on your internal docs, a deal-review assistant that pulls from Salesforce and Drive, or a support-reply drafter grounded in your help center. These custom apps extend Glean well beyond general search.
Is there a Glean free trial?
There is no public free trial or self-serve tier. Glean offers demos and pilots for qualified enterprise buyers typically at companies with 50+ employees. A typical pilot runs 30–60 days with a limited connector set and a subset of employees to validate ROI before signing an annual contract.
Glean vs Notion AI — which is better?
Notion AI is excellent if your team's knowledge lives mainly in Notion. Glean becomes necessary when knowledge is spread across Slack, Drive, Jira, GitHub, and dozens of other tools and searching across them is painful. Many companies use both: Notion for structured documentation and Glean for cross-app search and assistants.
Is Glean secure for enterprise data?
Yes. Glean is SOC 2 Type II certified, offers SAML SSO, supports audit logs, and operates with strict tenant isolation. Permission inheritance from source apps ensures employees only see content they already have access to. Enterprise customers can negotiate data residency, retention, and additional compliance terms in their contracts.
