An org chart is a diagram of who reports to whom. Each person hangs under their manager, from the top of the company down to every individual contributor. It answers the questions a new hire asks in week one and a director asks every quarter: who runs this team, how large is it, and who sits between me and the person I need.
Most companies keep the chart as a slide or a spreadsheet. Someone owns it, someone forgets to update it, and within a quarter it describes a company that no longer exists. The reporting line is real data, but the chart is a picture of that data taken on one day.
OrgOrg's Org Chart app is not a picture. It reads the Manager field on every People Profile and renders the result on demand, as a collapsible tree or a flowchart. The field syncs from Google Workspace, Microsoft Entra ID, or Gusto, or an admin sets it by hand. Change the field and the chart, the profile page, and every group built on the reporting line move together.
The chart opens at your own place in the org, so you see your manager, your peers, and your reports first. A search box finds anyone by name or email and opens their profile. Each row carries a count of everyone below that person, at every depth, so the size of a team is visible without expanding it.
