What the Concepts page shows
The Concepts page has two parts: the interactive Concept Graph on top and a list of Concept cards below. Each card shows the Concept’s name, a short summary, and how many citations and source files it’s built from. This article covers getting around that page and opening a single Concept’s details.Open the Concepts page

- In the left sidebar, click Concepts. The page opens under the heading Project Concepts.
Search and sort the list

- Click the Search concept names box above the list and type to narrow the cards to matching names.
- Click the Sort by dropdown to reorder the list: Created by you, Chief (surfaced automatically), Recent, or oldest first.
Switch between card and row views

- Use the view toggle at the top-right of the list to switch between a card grid and a compact row layout, whichever is easier to scan.
Open a Concept’s details

- When a passage list is long, click the + N more sources control to reveal the rest.

Frequently asked questions

What's the difference between citations and files in the count?
What's the difference between citations and files in the count?
Citations are individual passages; files are the documents those passages came from. One file can contribute several citations, so the citation count is usually higher than the file count.
