Natural Language Workflows (NLW) are AI automation rules written in plain English rather than code, decision trees, or flowcharts. They describe what the AI should do in conversational language that non-technical teams can read and modify.

Traditional support automation requires building rigid decision trees: if the customer says X, then do Y. This approach breaks on the infinite variability of human language. NLWs flip the model—you describe the intent, conditions, and desired outcome in prose, and the AI interprets customer messages against that description.

An NLW might read: "When a customer asks about their order status, look up their most recent order. If it shipped, share the tracking number and expected delivery date. If it hasn't shipped, check if it's delayed and explain why." This replaces dozens of branching rules with a single readable policy.

The power of NLWs is maintainability. When your return policy changes, you update one document rather than tracing through a flowchart. When edge cases emerge, you add clarifying sentences rather than new branches. Product teams can write and modify workflows without engineering support.

NLWs work because modern language models can parse intent from prose—but they require clear, complete descriptions. Ambiguous NLWs produce ambiguous AI behavior.
