Workflow Builder

Compose multi-step automations on a visual canvas: triggers, model steps, tools, and branches. Run, test, and version them so prompt chains become editable products.

Overview

How might we design workflow builder so people can trust and act on AI output?

When to use

  • Perfect for automation platforms, integration tools, and workflow management systems where visual workflow creation makes complex automation accessible to all users.

When to skip

  • One-off chats that will never be reused as automation.
  • Users who only need a single prompt template without branching or schedules.
  • When the platform cannot sandbox runs, builders without dry-run are dangerous.

Rules

  • Infinite canvas with no test-run, logs, or version history.

  • Nodes that hide API keys and side effects inside opaque “AI step” blocks.

  • Publishing to production without a draft/test environment.

  • Visual builders that still require writing glue code for every useful connector.

FAQ

What is an AI workflow builder?

An AI workflow builder is a visual editor for multi-step automations that combine triggers, model calls, tools, and branches, with run history so teams can maintain AI processes like ordinary software.

How is it different from prompt chaining?

Chaining is the step logic. A workflow builder is the product surface (canvas, connectors, scheduling, permissions, and monitoring) used to author and operate those chains.

What must a builder expose for trust?

Per-step inputs/outputs, failure handling, credentials scope, and a dry-run or test mode before enabling live side effects.

Who is the primary user?

Ops, PMs, and power users who need reliable repeatable jobs. Pure end-user chat can call published workflows without opening the canvas.
