Koito

Koito is a lightweight, self-hostable collaborative knowledge base and note-taking platform designed to help teams and individuals capture, organize, and link ideas with the reliability of a local or private server rather than relying on managed SaaS tools. It combines concepts from wikis, Zettelkasten systems, and modern note apps by letting you create interconnected notes, bidirectional links, and structured collections that mirror how knowledge naturally grows. The interface supports markdown editing with live preview, tag management, and graph-style browsing so you can explore relationships between pages instead of treating documents as isolated files. Because Koito is self-hosted, you retain ownership of your data and can integrate authentication systems for team access control. It also includes collaboration features like real-time editing or change history, making it suitable for team documentation, research projects, and personal knowledge management alike.
