Knowster: AI-powered Site Assistant

Self-hosted knowledge base platform where teams upload documents and get answers through a chat interface. Users ask questions in natural language and get responses grounded in their actual documentation, not generic AI answers.

Supports PDF, Markdown, and text documents. Semantic search finds relevant content across the entire knowledge base. Chat interface provides sourced answers with references to specific documents.

Self-hosted on Docker, all data stays on the client’s infrastructure. No external API dependencies for document storage or search. Works with Claude and other LLM providers for the chat layer.

Built for teams that need internal documentation accessible through conversation without sending sensitive content to third-party SaaS platforms.
