Best IT Knowledge Base Software in 2026

IT knowledge base software gives teams a way to keep technical guidance and operational instructions accessible. Compared on AI-powered search and runbook support, the entries also show options for an internal employee portal and access through Microsoft Teams or Slack. Single sign-on may be relevant to how staff access that knowledge, while free-plan availability and paid-from pricing help with cost comparisons. CompassDocs, iTop and Scribe are among the options shown. Consider where employees look for answers, whether they need runbooks as well as reference material, and which access methods fit your environment.
