Top-Rated Knowledge Base App for Small Businesses

Curious to hear what the community recommends when it comes to lightweight, effective knowledge base platforms for small teams. The goal: keep internal info accessible, organized, and easy to update without adding operational overhead.

Here are a few standout options on G2:

1. Notion: All-in-one workspace that’s flexible for docs, wikis, and task tracking. How well does it scale as a true knowledge base when teams start to grow?
2. ClickUp: Known for project management, but it also supports docs and internal knowledge. Is it strong enough to replace a standalone KB tool?
3. IT Glue: Built for IT documentation with structure and version control. Is it too technical for general team-wide use?
4. Slack: While not a KB in the traditional sense, many teams use it for quick info sharing. Does it hold up for long-term reference and organization?
5. Confluence: A long-time favorite for internal wikis and documentation. How intuitive is it for small, non-technical teams?

Would love to hear from teams who’ve put these tools into action, what’s easy to maintain, and what gets messy over time?
