Air.Build vs Smile Code

Build apps with a coordinated team of AI agents. Air.Build brings product planning, design, development, review, naming, website work, and App Store guidance into one organized workspace. Start with an idea or import a GitHub repository, then keep conversations, files, decisions, and build activity together as your project moves forward. WORK WITH SPECIALIZED AI AGENTS Bring the right role into each conversation. Product, Design, Developer, Reviewer, Naming, Website, and App Store agents collaborate while keeping responsibilities clear. KEEP EVERY PROJECT ORGANIZED Create a project or import an existing GitHub repository. Follow project and private conversations, reply to messages, review attachments and files, and keep up with project activity without losing context. MOVE WORK FORWARD Use focused conversations and structured actions to make decisions, guide AI agents, and keep each project moving. CONNECT THE TOOLS YOU CHOOSE Connect GitHub to bring in existing code. If you use your own supported AI provider, add your model key from account settings. Air.Build is for developers, designers, and founders who want one place to coordinate the work behind an app. Some features require an Air.Build account, an invite code, or connected third-party services.

Your ideas keep coming, even when you no longer want to sit at your computer. ——·—————— An Agent is still working on a task. You have just thought of a change and want to tell it now. Several projects are running, and you keep searching for the right conversation. Smile Code is made for these moments. Connect to your own Mac and bring your Agent conversations to your iPhone. Find a comfortable spot on the same local network and keep Vibe Coding. ——·—————— ▸ A design you will want to open every day Smile Code's developer is a designer first. A black background. The feel of aluminum. Like holding a familiar little device, rather than opening another chat window. Turn the wheel to browse conversations. Press to enter a task. Subtle sound and haptics respond to every step. Even checking progress and switching conversations can be fun. ▸ Say what comes to mind “Give this a little more space.” “Make the button bigger.” “Fix this issue first.” You do not have to type a long message on your phone. Speak your idea, turn it into text, review it, then send. A personal vocabulary and editable vocabulary packs help with technical terms that are hard to recognize. You can also download local speech models or configure your own AI text-polishing service to suit the way you work. Less typing when inspiration strikes. ▸ All connected conversations, together No need to remember which Agent has the task. Open Agents to see conversations from your connected tools in one place. Want to focus on one Agent? Apply a filter. Ready for another task? Turn the wheel, select it, and open it. You can switch to keypad controls, too. Let the tool fit your habits. ▸ Check your computer without going back to your desk Open the live Mac preview to see the screen. Use your phone for pointer and scrolling controls when needed. Check whether the interface looks right or see how a task is progressing. One less trip to your desk. One less interruption. ▸ A user first, a developer second That is the idea behind Smile Code. Its developer is also an avid Vibe Coding user. We know the urge to check on an Agent while it works. We know a change that takes one sentence to explain can be awkward to type. And we know a useful, thoughtfully designed tool makes you want to keep creating. That is why Smile Code pays attention to everyday use. From spacing on the screen to the feel of the wheel. From editing vocabulary to switching conversations. We hope you will think: “Yes. This is what I needed.” Let your Mac keep working. Pick up your iPhone and keep your next idea moving. Before you start: • Requires iOS 18 or later and an Apple silicon Mac running macOS 26 or later. • Install the Mac companion and connect both devices to the same trusted local network. Keep your Mac awake with the companion running. • Scan the Mac QR code for secure pairing. Conversations, controls, and previews travel over encrypted connections. • Cross-network relay is not currently available. Notifications may not arrive while the app is in the background or the phone is locked. • Install, sign in to, and authorize third-party Agents yourself. Features and fees depend on each service. • AI text polishing is off by default. When enabled, transcribed text and selected vocabulary are sent to the provider you configure.
