Confluence

Confluence is Atlassian's team collaboration and documentation platform, serving as the knowledge hub for organizations worldwide. It provides a structured environment for creating, organizing, and sharing team documentation, meeting notes, project plans, product requirements, and institutional knowledge.

The platform uses a hierarchical structure of spaces and pages that mirror organizational structures. Teams can create rich content with an intuitive editor, embed dynamic content from Jira and other tools, and use whiteboards for visual brainstorming and diagramming directly within the platform.

Confluence integrates deeply with the Atlassian ecosystem, allowing teams to link Jira issues to documentation, embed Trello boards, and connect with Bitbucket repositories. Atlassian Intelligence provides AI-powered features including content summarization, writing assistance, and smart search across all organizational knowledge.

Enterprise features include advanced permissions with space-level and page-level access controls, data residency options, audit logs, and organization-wide analytics. Confluence is available as Cloud, Data Center (self-managed), or Server deployments, though Atlassian is actively migrating customers to Cloud. The marketplace offers thousands of apps for extending functionality.
