Monad Design / Early preview
The app is the canvas.
Design mobile native apps from the state that actually exists. Point to what should change and let your coding agent implement it in the repository you already use.
Early preview for local iOS development on macOS.
Feedback stays attached to the real product.
No detached mockup, no guessing which screen state the request refers to. You and the agent work against the same running mobile app and the same source tree.
Show the exact state
Navigate the mobile app yourself, including screens that depend on account data, navigation, or interaction.
Point instead of overexplaining
Select an interface element or draw directly on the screen, then attach the implementation note.
Compare before deciding
Review the original and up to five alternatives in the same app state before choosing one.
Stay in control
Accept a result, keep the original, or keep refining. Every change remains inspectable in Git.
From running screen to reviewed source change.
The session stays open after each request, so design becomes a conversation with the product instead of a handoff document.
- 01
Start
Choose the current iOS app and Simulator.
- 02
Reproduce
Navigate to the exact state to preserve.
- 03
Describe
Select or annotate what should change.
- 04
Implement
The agent edits and rebuilds the existing project.
- 05
Choose
Compare the original and alternatives, then approve.
A complete visual implementation loop for mobile apps.
Work from the running product, send grounded context to your agent, compare real alternatives, and approve the result. The current preview supports local Xcode and Expo iOS projects on macOS.
In the preview
- Control a local iOS Simulator
- Select interface elements with visual context
- Annotate with shapes, arrows, text, and notes
- Request and compare one to five alternatives
- Use the iPad companion for touch and Apple Pencil
- Work with Codex, Claude Code, Cursor, Gemini CLI, Copilot, OpenCode, Windsurf, and Zed
You will need
- A Mac with Xcode and an iOS Simulator
- An existing Git repository with an Expo or Xcode app
- A supported local coding agent
- Image input support for annotated requests
Same repository. Local evidence. Your approval.
Monad Design only works with projects and Simulators you explicitly choose. Captured evidence stays local and is excluded from Git by default; your agent edits the repository you can already inspect.
