Built For

Your role. Your workflow.

Designers

Tweak real UI instead of writing specs and hoping the result matches.

PMs

Prototype flows and onboarding directly in the product, not in slides.

Design Engineers

Move faster with AI-assisted multi-file edits and visual feedback loops.

The Idea

Aule turns product ideas into shipped UI changes, without pulling you into terminals, build scripts, or repo archaeology.

1

Your app is the interface.

2

The AI is your design engineer.

3

The code stays real.

How It Works

From repo to result in three steps.

>Detecting stack...Next.js 16
>Installing deps...done
>Starting dev server...ready
>App loaded.
Step 1

Open a project. See the real app.

Drop in a repo. Aule detects the stack, installs dependencies, starts the dev server, and loads your app in a native macOS workspace. No setup rituals. No guessing scripts. Just the product, running.

Click to edit
Step 2

Point, click, change.

Hover any element to inspect it. Click to edit text, layout, and behavior. Aule maps UI to components to files and applies precise code edits.

"Add a 3-step onboarding after signup."
Planning across 4 files...
Applying changes...
Done. 3 new components created.
Step 3

Ask for features, not tickets.

Describe what you want in plain language. Aule plans the changes, edits multiple files, wires flows, reloads the app, and shows you the result.

Benefits

Why use this?

Build in context

Edit the real product, not static mockups or screenshots. Every change is grounded in live behavior and real state.

Skip toolchain friction

No manual server setup. No package manager roulette. No hunting for the right file.

Natural-language changes

Request copy updates, layout refinements, and full flows using plain language.

Branch out

Create visual Versions of your work. Switch and compare easily. Under the hood it's git, but you never have to think about it.

Engineer-ready output

Aule uses the same tools your enginners use, so well, its ready!.

Bring Your Own AI

Use your existing AI tools and subscriptions.

Aule connects to the coding agents you already pay for. No new API keys. No vendor lock-in. Just log in and go.

What It Feels Like

Aule is what happens when...

Figma becomes executable

DevTools become editable

AI becomes your design engineer

More time in the product.Less time in the tooling.More shipped work.
Safety & Control

You get speed without losing control.

Every change is sandboxed, tracked, and ready for review. Move fast with full confidence.

Applied to a Version, not production
Tracked and reversible
Visible as file changes and summaries
Ready for engineering review

If you can describe the experience you want, you can build it.

Aule turns intent into interface changes, directly in your codebase.
