Core concepts

Nexus is built around a small set of concepts. Once you understand them, the rest of the product follows naturally.

Nodes

Everything in Nexus is a node. A node is one of three types:

• Document — a page with a block editor. This is where you write.
• Folder — a container for other nodes. No editor content, just structure.
• Calendar entry — a document with a date attached. It appears on the content calendar.

All three types share the same tree structure. You can nest any node inside any other. A folder can contain documents, other folders, and calendar entries, all mixed together.

The tree

Nodes are organized into a single hierarchy — the node tree — visible in the left sidebar. Your whole workspace lives in this tree. There's no separate file system or database to switch between.

Each node has a parent (except top-level nodes, which sit directly in a teamspace). Moving a node is as simple as dragging it to a new parent.

Teamspaces

A teamspace is a top-level section of your workspace — like a department or a project area. The sidebar is organised by teamspace. Every node belongs to exactly one teamspace.

Teamspaces don't restrict access — all workspace members can see all teamspaces. They're purely organisational.

Workspace

A workspace (also called a business) is the top-level container. It has members, settings, and a shared node tree. Most teams only need one workspace. You can create multiple workspaces if you have separate organisations or clients that need complete separation.

Title vs name

Each node has two text fields: a title and a name. The title is the document heading — the large text at the top of the editor. The name is the label shown in the sidebar. By default they're the same. When you edit the title in the sidebar, the name becomes independent (shown with an edit icon). This lets you have a long descriptive document title and a short sidebar label.

Blocks

Document content is made of blocks — paragraphs, headings, lists, code blocks, images, tables, and more. Each block is an independent unit. You can drag blocks to reorder them, convert one type to another, or delete individual blocks without affecting the rest of the document.
