Dark AI Viewer with Course Website Preview

A screenshot of a desktop AI image viewer interface in dark mode showcases a preview of the generated website design. The overall canvas is charcoal gray, employing a minimalist, modern application UI. The top left corner features a small white sans-serif text title, "Thought for 2m 6s," accompanied by a subtly angled icon. The middle left displays a large rounded rectangle preview, showcasing a black-themed, luxurious landing page for a Japanese online course. Inside the preview, the website's main screen area has a black background, using elegant serif and sans-serif fonts. Above is a small English title, "ONLINE COURSES," and below is a large Japanese main title, "デザインとキャリアを、次のステージへ," with a smaller Japanese subtitle below that. The main content area of ​​the website contains six course cards arranged in a 3-column, 2-row grid. Each card boasts a sophisticated, cinematic, and high-end style, featuring atmospheric images, category tags, Japanese titles, brief descriptions, small circular lecturer avatars, and links in the "See details →" style. Card 1 showcases a UI design image with the main title "Thoughts and Programs on the Essence of UI Design." Card 2 displays a Figma-related screen image with the title "Figma Master Lecture Practice Edition." Card 3 showcases paper writing tools with the title "Technology for Information Design that Creates Distributed Structures." Card 4 showcases a STUDIO-themed visual with the title "STUDIO-themed No-Cod Web Design." Card 5 showcases a brand or book-like object, titled "Design and Expression of Brand Values". Card 6 showcases a portfolio/booklet, titled "A Portfolio Lecture with Delicate Features". Subtle gold-gray highlights, thin borders, and soft reflections are added to present a refined, high-end Japanese design aesthetic. The lower left corner of the preview image includes a white Japanese label "Catalog". The lower right corner of the preview image includes a small white share/export icon. On the far right of the application interface, four rounded square thumbnails are vertically stacked, representing other generated images; the first three thumbnails feature a light-colored theme page design, while the fourth thumbnail matches the dark course grid design. The fourth thumbnail is highlighted with a glowing blue selection border. The lower left corner of the overall screenshot includes two small white interface icons: a copy icon and a horizontal three-dot menu. The overall composition should present the quality of a real-world screenshot of an AI tool, with clear UI spacing, subtle shadows, and accurate screen capture for a realistic feel.
