Best Knowledge Base Tools 2026 - Frequently Asked Questions
What is the best knowledge base software?▾
Notion is widely used as an internal knowledge base for its flexibility and team familiarity. For customer-facing help centers, Zendesk Guide, Intercom Articles, and Help Scout Docs integrate tightly with their respective helpdesk platforms. Guru focuses on internal knowledge management with browser extension access. Confluence is the Atlassian ecosystem standard for technical team wikis.
How do I write good knowledge base articles?▾
Use question-format titles that match how customers phrase their problems. Write scannable articles with short paragraphs, numbered steps, and screenshots for processes. Cover one topic per article — link to related articles rather than covering multiple topics in one long piece. Update articles when products change. Analyze search queries with no results to identify missing content. Review article helpfulness ratings and rewrite low-rated articles.
What is a ticket deflection rate and how does a knowledge base improve it?▾
Ticket deflection rate is the percentage of potential support requests resolved through self-service (knowledge base, chatbot, FAQs) before a ticket is submitted. Good knowledge bases with discoverable content can deflect 20-40% of potential tickets. Measure by tracking searches that end without ticket submission, tracking article views before ticket creation, and asking in the ticket submission flow 'Did our help center answer your question?'
