For enterprise knowledge base AI search, the most important thing is not how beautiful the answers are, but permissions, connectors, citation sources, and knowledge maintenance. Glean, Guru, Notion AI Enterprise Search, and Slite Ask can all "ask about company information," but the teams suitable for them vary greatly.
First, select according to organizational scale
| Tools | Suitable for the team | Not suitable |
|---|---|---|
| Glean | For medium and large enterprises, data is scattered across multiple systems such as Slack, Drive, Jira, and Confluence | Small team materials are mainly stored in a single document library |
| Guru | Customer service, sales, and operations teams need to validate mechanisms, knowledge leaders, and audit leads | People who only want to do light Q&A and don't want to maintain their knowledge |
| Notion AI Enterprise Search | The company's core documents are already in Notion, and I want to connect to Slack, Google Drive, and others | Organizations with no need for Notion or very complex permission structures |
| Slite Ask | Remote teams, product teams, and small to medium-sized companies with standardized documentation | Companies that need to cover a large number of enterprise systems and complex audits |
Do a small test before purchasing
Test with 20 real questions employees often ask: leave process, pricing policies, customer cases, product restrictions, permission requests, and troubleshooting. I don't know if AI will cite it, respect permissions, or admit it. You can't just test the public manual, as that won't reveal the true search capabilities of the company.
My advice
The data is scattered and the number of participants is large, so prioritize evaluating Glean; You need "who is responsible for this piece of knowledge, when it expired, who has verified it," and look at Guru; Already a heavy user of Notion, starting with Notion AI Enterprise Search; Teams tend to have centralized documentation and want lightweight implementation, so Slite Ask is simpler.
Who is it not suitable for? If your company's knowledge base is messy, your files are neglected, and permissions are opened at will, don't rush to buy AI search just yet. AI only exposes chaos more quickly and cannot automatically build knowledge governance for you.
