A browser-based SaaS AI writing assistant rendered as a MacBook Pro 14-inch screen mockup, shown at a slight upward tilt on a white marble surface. The interface uses a three-column layout. Left sidebar (200px wide): document tree listing "Introduction", "Chapter 1", "Conclusion" in 14px Inter Regular, a "New Document" button in muted blue outline style, and a search field at top. Center editor panel (flexible): a large open writing canvas with Times-like serif body text reading "The light shifted across the harbor at dawn, painting the fog in shades of amber and steel." as sample text; a blinking cursor. Toolbar above the canvas has minimal icons: Bold, Italic, Heading, Link, and an AI sparkle icon. Right panel (280px): an AI suggestions panel with a frosted white card showing "Suggested continuation:" above two tonal chips labeled "Lyrical" and "Concise"; below, a suggested text in lighter gray italic. Palette: white (#FFFFFF) and near-white (#F9F9FB) surfaces, blue (#2563EB) accents, neutral gray text. No decorative elements; every pixel is functional.
