Get your first Heym workflow running in minutes.

Get your first Heym workflow running in minutes.

Do not have Heym running yet? See Running & Deployment, or follow the video walkthrough: Set Up Heym Locally in Under 2 Minutes.

1. Create a Workflow

  1. Go to the Workflows tab
  2. Click New Workflow
  3. Name your workflow (e.g. "Hello World")

2. Add Nodes

  1. Open the Nodes panel on the left
  2. Drag an Input node onto the canvas
  3. Drag an LLM node and connect it to the Input
  4. Drag an Output node and connect it to the LLM
[Input] --> [LLM] --> [Output]

See Node Types for all available nodes.

3. Configure

  • Input: Set a default value or leave empty for user input (see Input Node)
  • LLM: Select a credential and model, add a system instruction, and set userMessage to $input.text (see LLM Node)
  • Output: Set message to $llm.text to pass through the LLM response (see Output Node)

Use Expression DSL syntax for $input.text and $llm.text. Click the expand button on expression fields for the Expression Evaluation Dialog with live backend preview.

4. Run

Click Run, press Ctrl + Enter, or use the debug panel to execute. The workflow runs from the Input node through connected nodes to the Output. See Triggers for other ways to run workflows (webhook, portal, cron, etc.).

View past runs in History (toolbar) and use Bring to Canvas to re-run with the same inputs.

On Docs, Evals, and other non-canvas internal pages, you can also use the Quick Drawer to pick a pinned workflow and run it without going back to the editor.

If you are reading the docs and want clarification before building, open Chat with Docs from the Docs header to ask page-aware questions.

Alternatively, use the AI Assistant from the Debug panel to create workflows with natural language—describe what you want and the AI generates nodes and edges.

Already building automations in another tool? Migrate to Heym converts an n8n, Flowise, Dify, Langflow, sim.ai, or Activepieces workflow into a Heym workflow you can import.
