# NLX (Natural Language Experience) Design Stack

## Overview

A framework defining the new principles and UI constructs required for **Natural Language Interfaces**. Moves beyond simple chat to structured, designed conversations.

**Core principle:** NLX is the new UX. Conversations have grammars, structures, and invisible UI elements.

## The Four Elements

## Key Principles

| Element | Principle |
|---------|-----------|
| **Prompts** | Treat prompts as distinct UI elements (like dropdowns) |
| **Plans** | Return structured, editable plans for complex goals |
| **Process** | Visualize reasoning to build trust ("thinking aloud") |
| **Follow-ups** | Proactively suggest next steps ("happy path" guidance) |

## Common Mistakes

- Assuming "the model is the product" (neglecting design)
- Making the AI a black box without feedback
- Failing to guide users after an output
