What is knowledge base software?
Knowledge base software is a platform used by companies to easily store, organize, retrieve, and share information with employees and/or customers. This information can include company policies, procedures, work instructions, and best practices, among other things.
A finely tuned knowledge management software helps companies control how information and knowledge flow within (or outside).
For example, Scribe can quickly produce internal and external process documents for any task or procedure. Scribe also allows you to store, organize, retrieve, and share information with anyone —internally or externally.
