The payoff: a reusable slice of your Library
A Collection is a saved filter that fences off part of your Library using your Labels. Instead of hunting for the same set of files over and over, you define the rule once — “everything labeled Q3 Planning but not Archived” — give it a name, and Chief keeps that group up to date for you. Open the Collection any time, or pull its whole contents into a task in one click.
A worked example

Why Collections beat re-filtering every time
- They’re saved. Define the rule once; it stays on your Collections page with a live file count.
- They stay current. Because a Collection is a rule about Labels, files flow in and out as you label them — you never re-curate a static list.
- They’re task-ready. Hover over a Collection and click Start task to power a conversation with exactly that slice of your Library, or Visualize to turn it into a graphic.
ℹ️ Good to Know: A Collection holds a filter, not copies of files. Deleting a Collection removes the saved rule only — your files and their Labels are untouched.
Collections vs. Labels
A Label is a tag on a single file. A Collection is a rule that combines one or more Labels with AND/OR logic to define a whole group. Labels are the building blocks; Collections are what you build with them.Frequently asked questions
Do I need an upgraded plan to use Collections?
Do I need an upgraded plan to use Collections?
No. Collections are available to use; you only need to be signed in. Creating one prompts a sign-up if you’re browsing as a guest.
If I delete a Collection, do I lose the files in it?
If I delete a Collection, do I lose the files in it?
No. A Collection only stores the filter rule. Deleting it removes the rule — your files and Labels stay exactly as they were.
Do Collections update on their own?
Do Collections update on their own?
Yes. Because a Collection is a rule about Labels, files appear or drop out as you add or remove those Labels. There’s no list to maintain by hand.
Can I build a Collection without any Labels?
Can I build a Collection without any Labels?
No — Collections are built from Label filters. Create and apply at least one Label first, then build a Collection around it. See “Building a Collection with AND/OR Label filters.”
