Glean, The Jouster's Review

The Essentials

• Enterprise AI search engine that indexes all internal organizational tools
• Custom pricing, mid-market and enterprise positioning
• Semantic search across Slack, Google Drive, Confluence, Jira, Salesforce, and 100+ sources
• Targets mid-to-large companies that want to find information scattered across their tools

What Is Glean?

Glean is an AI-powered enterprise search engine. The problem it solves is universal in organizations of significant size: information is scattered across dozens of tools (Slack, Google Drive, Confluence, Notion, Jira, Salesforce, GitHub...) and finding something takes considerable time. Glean indexes all these tools and offers a unified semantic search engine. You ask a question in natural language ("What's the expense reimbursement policy?") and Glean finds the answer in the Confluence doc that explains it, the Slack conversation where it was discussed, and the presentation that summarizes it. It's an organizational knowledge assistant.

Strengths

100+ Enterprise Source Indexing

The number of integrations is very wide: GSuite, Microsoft 365, Slack, Confluence, Jira, Salesforce, GitHub, ServiceNow, Zendesk, and many more. It's the most complete tool in the category.

Semantic Search vs Keyword

Glean understands the meaning of questions, not just keywords. "How do we request time off?" will find the right documents even if the word "time off" isn't in the title.

Permissions Respected

Glean respects the permissions of source tools. If a document is private in Google Drive, it doesn't appear in results for those who don't have access. Security is a strong point.

Limitations

Enterprise Pricing Inaccessible to SMBs

Glean is priced for large organizations. The per-user price is significant and minimum contracts generally require multi-year commitments.

Value Depends on Existing Chaos

Glean is most useful when the organization is large and information is scattered. For a 10-person startup with a well-structured Notion, Glean is unnecessarily expensive.

Pricing

Custom pricing. Contact glean.com for a quote tailored to organization size.

Alternatives

Glean = enterprise AI search. Notion AI alternative = search within Notion only. Guru alternative = knowledge management + search, $10/month. Microsoft Copilot alternative = search within Microsoft 365 ecosystem.

Verdict

Glean is recommended for 200+ person organizations that have a real information retrieval problem across their internal tools. Below that size, more accessible solutions like Guru or a well-organized Notion suffice.
