Private Knowledge Base

A private knowledge base is a document search and knowledge management system in which an individual or organization controls the data, access permissions, and deployment environment. It often supports full-text search, semantic retrieval, RAG-based question answering, and internal AI assistants. This page compares deployment models, supported AI models, document parsing, retrieval quality, permissions, security, hardware requirements, and maintenance costs for tools that work with PDFs, web pages, internal documents, databases, and code repositories.
