Questions & answers
What are the key differences between Notion and Glean?
Notion is a comprehensive workspace solution that integrates AI-powered search with knowledge management and collaboration features in one platform. Glean functions primarily as a standalone search layer atop your existing tools. While Glean focuses narrowly on search functionality, Notion delivers a complete ecosystem that enhances productivity, knowledge sharing, and collaboration—all secured with enterprise-grade controls.
How does the enterprise search quality compare between Notion and Glean?
Notion delivers actionable answers from complex queries across multiple documents, not just links for keyword searches. Notion AI goes beyond keyword search, delivering comprehensive summaries and actionable responses with clear citations. By comparison, Glean primarily returns keyword-based results without comprehensive synthesis and has limited contextual understanding without deep cross-document synthesis.
How do Notion and Glean compare on security and data privacy?
Notion and Glean both integrate with many workplace apps, but they differ in data handling. Notion’s AI respects your content permissions and does not train on your private data (your data isn’t used to train AI models). All data stays within your Notion workspace or your integrated storage, and Notion is certified for SOC 2, ISO 27001, GDPR, etc., with encryption in transit and at rest. Glean, as an external search layer, creates an index of your company’s data from other apps. It also respects app permissions, but by design it stores copies or embeddings of your data to build its knowledge graph.
What are the cost differences between Notion and Glean?
Notion AI is included with Business and Enterprise plans with transparent, flexible pricing. Glean typically requires high minimum commitments (starting at $100K+ annually) with limited scaling options. By consolidating your tech stack with Notion's comprehensive AI workspace, you can eliminate the need for multiple point solutions and reduce overall costs.
How do the collaboration features compare?
Notion offers real‑time co‑editing, comments, tasks, and project tracking inside the same workspace where knowledge lives. Glean surfaces results but typically relies on connected tools (e.g., Slack) for collaboration; it doesn’t replace a collaborative doc hub. Knowledge isn't automatically documented for future team reference.
How does each platform integrate with other tools?
Notion connects to numerous platforms including Slack, Google Drive, MS Teams, SharePoint, OneDrive, Gmail, Linear, and more. Glean also offers a larger volume of connectors and does support custom tools, however Slack has recently blocked Glean from using Slack data, which may impact its effectiveness.
