Every HTML file you generate with AI deserves a proper home — and a proper canvas. HTML Viewer is the studio built for the age of AI-generated code. Whether you're creating dashboards, prototypes, or data visualizations from any AI assistant or large language model, this app gives your HTML artifacts the full-fidelity rendering environment they deserve. IMPORT FROM FILES, INSTANTLY Bring in any HTML file straight from the Files app — iCloud Drive, local storage, or any connected provider. No copy-pasting, no workarounds. Tap, import, and render. ORGANIZED THE WAY YOU WORK Build a nested folder structure and manage all your HTML files in a collapsible file tree. When it's time to focus, one tap hides the entire sidebar and expands the canvas to fill your screen. TABS AND SPLIT VIEW Open multiple HTML files at once with a clean tabbed interface, or activate split view to compare two files side by side. Perfect for reviewing iterations, design variations, or before-and-after states across your projects. YOUR FILES, YOUR DEVICE Everything stays on your device. No uploads, no remote servers, no accounts required. Your files are stored privately on-device by default. HTML Viewer is the tool that was missing from every AI-assisted workflow. Download it today and give your artifacts a studio-grade home.
