Quick take
Where Cache and Capacities diverge
Capacities is a strong choice for users who want object-based PKM for mixed media. Cache makes more sense if your problem is broader: too many saves, too many platforms, and too little reliable retrieval when something becomes relevant again.
Primary use case
Dedicated saved-content retrieval and organization.
General-purpose notes, databases, or knowledge graphs.
Rediscovery style
Search and collections centered on saved media and links.
Queries, notes, databases, or graph relationships.
Organization model
Opinionated around capture and later usefulness.
Highly flexible but often user-defined and system-heavy.
Best if you want
A dedicated layer between saving something and operationalizing it.
A broader workspace for projects, notes, and structured knowledge.
Choose Cache if
You want a working library, not just another destination.
Choose Capacities if
You mainly want Capacities's native workflow.
