Brain graph

On this page

The brain graph shows the records of your TDT brain as nodes, and the links between them as lines. It needs TDT 0.1.12 or later.

Open the brain graph

Do one of these steps:

  • In the left rail, click Brain.
  • On a record, click Brain. The graph opens and finds that record.
  • In a project, chat or widget, click Open brain.

Read the graph

Each node type has a colour. The legend shows the types and the number of nodes of each type: Index, Projects, Knowledge, Candidates, Scratchpad and Tags. The index and the projects are hubs: the layout puts the other nodes around them.

To hide a node type, click it in the legend. Click it again to show it.

The stats bar shows the number of nodes and links, the zoom level and the status. The status is LIVE when Helm shows your brain. In offline mode, the status is SAMPLE DATA.

Move around

  • Drag the background to move the view.
  • Use the mouse wheel, or Zoom in and Zoom out, to zoom.
  • Click Fit to show the full graph.
  • Drag a node to move it.
  1. Type in Search the brain….
  2. Helm finds nodes by title or by type name. If you type 2 or more characters, Helm also searches the text of the records.
  3. Press Enter to select the first result, or click a result in the list.

Search does not find nodes of hidden types.

Inspect a node

Click a node to select it. The inspector shows the type, and the buttons for that node:

  • Read record opens the record. See Knowledge editor.
  • Open opens a project.
  • Ask Helm starts a chat with the question "What do we know about {node}?".

The Connections list shows the linked nodes. Click one to go to it. To close the inspector, click Close or click the background.

If the graph does not load

  • "The brain graph needs TDT 0.1.12 or newer (tdt_brain_graph).": update TDT, then click Retry.
  • "Couldn't load the brain graph: …": read the cause, correct it, then click Retry.
