Use the following brief to design a logo for product "AI Second": Logo name AI Second Overall feeling Calm, intelligent, trustworthy. Human-centered rather than technology-centered. Suitable for educators, school leaders, and researchers. Minimal enough to sit comfortably on presentation slides. Visual style Flat vector design. One-color version must work perfectly (black on white). Avoid gradients, 3D effects, glowing AI aesthetics, circuit boards, robot heads, or chat bubbles. Thin to medium line weight, consistent with sketchnote-inspired visuals. Concept The logo should communicate that AI comes second—human judgment comes first. Possible symbolic directions (choose one): A simple human figure positioned before or slightly larger than a subtle AI-related element. The word Second visually emphasized more than AI. A small "2" integrated into the design as a secondary layer. Two simple geometric shapes where the human-related shape visually leads and the AI-related shape follows. Typography Modern sans-serif. Mixed case preferred: AI Second Clean, generous spacing. No futuristic or sci-fi fonts. Color Primary: black. Optional accent: muted teal or deep blue, used sparingly. Must remain recognizable in pure monochrome. Personality Thoughtful. Confident. Educational. Ethical. Timeless rather than trendy. Key message AI is a powerful assistant—but never the primary thinker. Human judgment comes first.
