Quick start

This guide takes you from a blank canvas to a running flow in a few minutes. No code required.

1. Open the builder

Open the Sobmit app. A fresh canvas already contains a Start node and a seed flow (Start → Agent → Output) so you can press Run immediately.

2. Add a Prompt node

Right-click the empty canvas and choose Add → Prompt, or open the Add menu in the navbar and pick Prompt. The node appears on the canvas.

Select it and type your instruction into the Text field in the inspector, for example:

Write a two-sentence summary of what this workflow builder can do.

3. Add an Agent node

Add an Agent node the same way. It comes with a default model selected. The Agent is the “brain” — it calls a language model with the text it receives.

4. Add an Output node

Add an Output node. This is where the final result lands and becomes visible.

5. Wire them together

Drag a connection from each node’s right handle to the next node’s left handle:

Prompt → Agent (into its prompt handle, to override the instruction).
Agent → Output (into its In handle).

The Prompt text travels into the Agent, the Agent’s answer travels into the Output.

6. Run the flow

Press Run flow in the right-hand panel. You will see the nodes light up in order, and the final answer render in the Output node. The Run timeline in the sidebar shows how long each step took.

What just happened

A run is the execution of your flow. The engine walks the graph from the Start node, passes data along the edges, executes each node, and collects the result at the Output. Runs are durable — you can come back later and see the result in the run history.

Next steps

Core concepts — how nodes, edges, handles and runs fit together.
Agent — structured output, vision, PDF input.
Webhooks — trigger this flow over HTTP.
