## FAQ

**What is the difference between a knowledge base and a wiki?**

A knowledge base is typically more structured, with curated articles managed by specific teams (like support or product) and focused on providing official answers. A wiki, like Confluence, is often more collaborative and open, allowing any user to contribute and edit pages, making it ideal for internal team knowledge and project documentation.

**Can I use Notion or Confluence as a customer-facing knowledge base?**

Yes, both can be used, but they have limitations. Notion is highly flexible but lacks dedicated KB features like advanced analytics, ticket deflection workflows, and granular user feedback. Confluence can be adapted for external use but is primarily designed for internal, technical documentation and can feel less user-friendly for customers than dedicated tools like Zendesk or Document360.

**How much does knowledge base software cost?**

Pricing varies widely. Simple tools can start from $5-$10 per user/month. More comprehensive platforms bundled with help desks often range from $50-$100 per agent/month. Enterprise-grade standalone solutions like Document360 can start at $150-$500 per month for a project.

**What are the key features to look for in knowledge base software?**

Look for a powerful WYSIWYG or Markdown editor, robust search capabilities (ideally with AI), version control, content categorization, user feedback mechanisms, detailed analytics, customization options, and seamless integrations with your help desk and other key business tools.
