Frequently asked questions
What's the difference between a knowledge base and a wiki?
A knowledge base is typically customer-facing documentation designed for self-service support, whilst a wiki is internal collaborative documentation. Many platforms (Notion, Confluence, MediaWiki) serve both purposes, though specialised tools like Document360 optimise for customer knowledge bases and others like Slite focus on internal team wikis. The distinction is increasingly blurred as platforms add features for both use cases.
Which platform is best for customer-facing documentation?
Document360, Zendesk, and Freshdesk are purpose-built for customer-facing knowledge bases with strong SEO, analytics, and self-service search. Notion and Slite work well for internal teams. If you need ticketing integration, Zendesk and Freshdesk combine support and knowledge bases; for standalone customer documentation, Document360 is the most cost-effective dedicated solution.
How do I choose between Notion, Confluence, and Document360?
Notion excels at flexibility and affordability for cross-functional teams needing databases and docs. Confluence is the enterprise standard for developer teams already using Jira. Document360 is ideal if you need a dedicated, quick-deploy customer knowledge base without internal wiki complexity. Consider team size, budget, existing tool stack, and whether you prioritise internal collaboration or external customer support.
