What is HTMLSync?
HTMLSync transforms your AI-generated, single-file HTML applications from static local files into dynamic, multi-device web apps. It's designed for anyone who creates custom tools with AI and needs a simple way to access them—and their data—from anywhere, without writing a single line of backend code.
Key Features
⚡ Instant App Deployment Simply upload your self-contained HTML file, and HTMLSync instantly provides you with a live, accessible URL. Go from a local file to a functional web app in seconds, bypassing the complexities of traditional hosting and server setup.
🔄 Automatic localStorage Synchronization This is the core of HTMLSync. Any data your app saves to the browser's localStorage is automatically and seamlessly synced across all your devices. Update a to-do list on your laptop, and the changes are immediately reflected on your phone—no configuration needed.
🔐 Private and Public App Modes You have full control over who sees your app. Keep your personal tools entirely private and accessible only to you, or switch to public mode to share a read-only version with anyone via a direct link. This is perfect for showcasing projects or providing simple utilities to an audience.
🗂️ Integrated App Drawer For users who build a suite of personal tools, the App Drawer provides a seamless way to switch between your hosted applications. This slide-out panel lets you navigate your entire collection of custom apps without ever leaving the page you're on, keeping your workflow fluid and efficient.
Use Cases
The Unified Productivity System: You use ChatGPT to generate a custom habit tracker, a simple project task list, and a deep-work timer. By uploading them to HTMLSync, you can log your morning workout on your phone, manage project tasks from your work computer, and start a focus session on your tablet, with all data perfectly in sync.
On-the-Go Data Capture: You create a simple HTML form to track personal expenses. While you're out, you can quickly log a purchase on your phone. Later, you can open the same app on your laptop to review your spending habits, as the data you entered on the go is already there.
Sharing a Portfolio Piece: You’ve built a clever interactive calculator or a small browser-based game as a single HTML file. You can host it on HTMLSync in public mode to create a live, shareable demo for your portfolio or social media, allowing anyone to try it out without giving them the ability to alter your master data.
Why Choose HTMLSync?
HTMLSync isn't just another hosting platform; it's purpose-built to bridge the gap between AI code generation and practical, everyday use. While other platforms can host static files, HTMLSync is uniquely focused on solving the data persistence problem for simple, localStorage-based apps.
Zero Backend Friction: You don't need to learn about databases, APIs, or server management. If your app uses
localStorageto save data, HTMLSync handles the synchronization automatically. Your focus remains on creating great tools with AI, not on deploying them.True Data Ownership: Your data lives in your browser's
localStorage, not on a proprietary server you can't access. You're never locked in. You can always ask an AI to add an export feature to your HTML app, giving you the freedom to move your information whenever you choose.Designed for the AI Workflow: The platform was created specifically for the new wave of AI-generated personal applications. It directly addresses the most common limitation—being stuck on a single device—and turns your creations into truly useful, dynamic tools.
Conclusion
HTMLSync is the missing link for your personal AI-generated web tools. It empowers you to take full advantage of AI's creative potential by making your custom applications as accessible and convenient as any professional app. Stop juggling local files and start building a synchronized suite of tools that work for you, wherever you are.
