Any workflow in Runchat, even just a few nodes, can be turned into a reusable building block. There are two destinations and they solve different problems. Same workflow, two destinations, no extra work. Most useful workflows end up as both.

Tools

A Tool is a reusable node that lives inside Runchat, alongside media, Agent and Code nodes. Once published, you can add it to any other workflow and use it as a single node, even though a whole mini workflow is running underneath. The key thing about Tools is that they compound. A Tool you publish today becomes part of a bigger workflow tomorrow. That bigger workflow can itself become a Tool. Over time you end up with a set of capabilities specific to how you work. Your published Tools are also available to the agent. The agent searches for the tools it needs, so if the description is good, it will reach for yours on its own when relevant. For step-by-step publishing, see Publishing Tools. For how agents call them, see Agent Tools.

Apps

Tools are for people who use Runchat. Apps are for everyone else. An App is a published web page with its own custom interface, built for you by the agent as HTML, that runs your published Tools behind the scenes. You can share the URL with anyone, embed the App in a Notion page, or use it as the front-end for a workflow you sell or distribute. Visitors sign in with their own Runchat account and spend their own credits, so you don’t pay for other people’s runs. For full details, see Apps.

Adding tools to your nodes

To use a workflow as a node in your other workflows, add it to your nodes:
  1. On the dashboard, open the workflow’s … menu (or right-click its card).
  2. Choose Add to my nodes.
The workflow appears under Tools in the node picker (press Ctrl/Cmd+K, or click Browse all in the + menu), ready to add to any canvas. Agent nodes can attach it from their Tools button too. To take it back out, open the same menu and choose Remove from my nodes.
You don’t need to add a tool to your nodes for the agent to use it. The agent searches your published tools, and public ones, on its own.
