Direct preview pipeline
Every supported artifact flows through a single WKWebView harness, keeping interactive HTML, SVG, Markdown, and React previews in one reliable surface.
Native previews for AI agent files
Open HTML, Markdown, TSX, JSX, and SVG artifacts instantly on iPhone, iPad, and Mac with a focused WKWebView preview built for developers.
Built for the file gap
Every supported artifact flows through a single WKWebView harness, keeping interactive HTML, SVG, Markdown, and React previews in one reliable surface.
React, ReactDOM, Babel Standalone, Tailwind, and marked are cached from CDNs after first launch for smoother previews away from the network.
Import from Files, open with document handlers, or send artifacts through the Share Extension without leaving the iOS workflow.
Interactive simulator
The real app renders source files locally. This simulator shows the shape of the workflow: choose a file type, switch viewport modes, and watch the preview adapt.
Privacy policy
Artifact stores imported source files locally in the app's Documents directory and uses SwiftData for recents metadata. Rendering happens inside WKWebView. The app downloads preview engines from CDNs for caching, but it does not sell data, track artifacts, or upload source files to Sinuk services.
Support
For support, App Store questions, or security concerns, contact support@sinuk.dev. Include the file type, iOS version, and whether the artifact came from Files, Share Extension, or Open In.
