Creating a shared design language for AI at Align

Creating a shared design language for AI at Align

Align Technology (creator of Invisalign) had a need for a flexible system that could improve AI consistency without prescribing the same interface for every product.

I created an AI experience guide that helps product leaders, designers, product managers, and developers design more consistent AI experiences across Align’s product ecosystem.

ROLE

Product Designer

SCOPE

Create a shared foundation for consistent AI experiences across Align’s products and platforms.

TEAM

Myself

TIMELINE

4 months (ongoing)

WHAT I DID

Defined reusable AI components, interaction states, patterns, and language guidance, then built an interactive experience guide using Claude Code.

OUTCOME

Established a shared AI design language that helps product, design, and engineering teams align on how AI should look, behave, and communicate.

Align needed a shared AI language

As teams began exploring AI across different products and platforms, foundational experience decisions were being made independently.

There was no shared guidance for questions such as which AI icons or badges to use, how thinking and streaming should behave, how generated information should be presented, or what language should communicate AI behavior.

This created a need for a flexible system that could improve consistency without prescribing the same interface for every product.

A system spanning visuals, behavior, patterns, and language

I reviewed AI experiences being explored across Align’s platforms and identified the decisions that would benefit from shared conventions.

I organized the guidance into four connected layers:

  • Components — Icons, badges, and reusable interface elements

  • Interaction states — Thinking, streaming, loading, completion, and recovery

  • AI patterns — Conversation, search, recommendations, and explainers

  • Language — Shared terminology and reusable AI interaction copy

Together, these layers give teams a common starting point while leaving room for each product to adapt the guidance to its users and context.

01

Components

Icons, badges, and reusable interface elements that make AI recognizable.

02

Interaction states

Thinking, streaming, completion, and recovery across the AI response lifecycle.

03

AI patterns

Reusable models for conversation, search, recommendations, and explainers.

04

Language

Shared terminology and reusable copy for clear, consistent AI communication.

Turning the framework into an interactive resource

Turning the framework into an interactive resource

I designed and built the guide using Claude Code, transforming the framework into an interactive resource rather than a static collection of documentation.

The guide brings examples, usage guidance, interaction behavior, and language recommendations into one place. Building it in code also allowed me to evaluate patterns in context and explore a closer connection between design guidance and implementation.

I also began translating the AI language library into a reusable skill for tools such as Claude Code and Replit. The goal is to help teams apply pre-approved AI language within the tools they already use, reducing the gap between documentation and execution.

Outcome: Creating a foundation for consistency at scale

Outcome: Creating a foundation for consistency at scale

The AI experience guide established an initial shared framework for how Align identifies AI, communicates system behavior, and applies common AI patterns across products.

It gives cross-functional teams a clearer starting point for evaluating new concepts, makes inconsistencies easier to identify, and reduces the need to redefine foundational decisions for every experience.

The work also creates a foundation that can evolve beyond documentation toward guidance embedded directly within design and development workflows.
