Buyer's guide
What's the difference between an internal and external knowledge base?
An external knowledge base is customer-facing, designed for self-service support to answer common questions about a product or service. An internal knowledge base is for employees, housing company processes, training materials, and technical documentation to improve efficiency and consistency.
How does a knowledge base integrate with a help desk?
Most knowledge base tools integrate with help desks like Zendesk or Help Scout. This allows support agents to easily search for and insert articles into ticket replies. It also enables AI-powered bots to suggest articles to customers before they submit a ticket, deflecting common queries.
How to choose
- 1.First, define your primary audience: Is it for external customers (self-service) or internal teams (employee reference)? Some tools excel at one over the other.
- 2.Evaluate the editor and content management workflow. Your team will spend hours creating content, so ensure the editor is intuitive and supports collaboration features like versioning and approval workflows.
- 3.Test the search functionality from an end-user's perspective. A great knowledge base is useless if users can't find what they need quickly.
- 4.Check for critical integrations with your existing tech stack, especially your help desk, CRM, and team chat applications.
- 5.Analyze the reporting capabilities. To improve your knowledge base over time, you need analytics on what users are searching for, which articles are helpful, and where content gaps exist.
Frequently asked questions
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.
