Notes and knowledge base tools vary a lot in scope, from simple notebooks to encrypted note apps and workplace search systems. In April 2026, ToolVitals scored these products to show which ones looked strongest overall for this use case.
The ranking below uses ToolVitals score first, with GitHub stars as a secondary popularity signal when scores are close. That means a tool can rank highly on overall health and shipping even if it is not the most starred project.
