About NodePad

Agent on canvas. NodePad lays your AI conversations out on a canvas, so you try more ideas, keep the answers that hold up, and never lose the thread that mattered. You can then use the arrow keys to move the node around. You can then press delete to remove it or escape to cancel. Every message on a NodePad canvas is a node you can build on, and the model only ever sees the context you chose.
