# Visual Workflows
> Build multi-step automations that become callable tools in chat.
Visual workflows turn a repeatable process into a graph of inputs, LLM steps, tool calls, and outputs. Once published, the workflow appears in chat and can be invoked with `@`.
## How workflows work
```mermaid theme={null}
flowchart LR
Input["Input"] --> LLM["LLM node"]
LLM --> Tool["Tool node"]
Tool --> Transform["Transform or branch"]
Transform --> Output["Workflow output"]
Output --> Chat["Callable from chat"]
```
## Common patterns
Search, extract, summarize, and return a structured answer.
Clean a dataset, calculate derived values, and return a chart or table.
Classify incoming work, enrich it with context, and draft the next action.
Use browser automation MCP tools to verify flows and capture findings.
## Publishing a workflow
Add input nodes for the data the workflow needs.
Add LLM nodes for judgment and tool nodes for external actions.
Run the workflow against the same kind of request users will send from chat.
Published workflows become available through `@workflow_name`.
