Confluence is built for team documentation — specs, meeting notes, wikis meant to be referenced by many people over time. ContextOS is built for something narrower and more personal: the working memory of a project you're actively resuming, session to session.

The honest take
Confluence and ContextOS solve adjacent but distinct problems: one documents for a team audience, the other holds working memory for whoever picks the project back up, often just you.
