Nexus X builds it.
A full AI engineering workspace: multi-file project generation, an offline live preview engine, reviewable auto-fix patches and version history — with the right model picked for you on every single message.
Multi-file artifacts
Ask for an app and get a whole project — file tree, entry point and all — not a lonely snippet.
Live preview
