Glean review

AI assistant that answers across all your apps.

Verdict

Glean is the contrarian pick, an AI-native enterprise search assistant that indexes knowledge across dozens of apps like Google Drive, Slack, and Jira and answers questions from all of them, rather than storing documents itself.

What customers praise

Its permission-aware AI search reaches wherever knowledge actually lives, so it answers questions no single-wiki tool can because the source spans many systems.

What customers criticise

It is a search and answer layer, not a place to author or govern documents, and its enterprise pricing puts it out of reach for small teams.

Best for

Larger organizations that want AI search and answers across every connected app, not just a single wiki.

At a glance

• Integrations: Google Workspace, Slack, Microsoft 365, Jira, Confluence, Salesforce
• Compliance: SOC 2 Type II, ISO 27001, GDPR, HIPAA
• Regions served: Global SaaS
• Typical onboarding: 30 days

Red flags

Public risk signals as of July 2026: low. Glean is a category-adjacent AI enterprise search tool rather than a document store, so buyers seeking authoring and governance may find its scope narrower than a traditional knowledge base. See the full red-flag report.
