#Lettermark

Design a minimalist lettermark logo for an AI SaaS startup named "[Company Name]". Build the icon from the company's first initial as one bold geometric letterform of clean intersecting lines, with a small circuit node or spark tucked into the letter's negative space. Deliver a horizontal lockup: icon on the left, the wordmark "[Company Name]" set in a modern geometric sans-serif to its right, and the tagline "[Slogan]" in small letter-spaced uppercase beneath the name. Palette: indigo #4F46E5 to violet #7C3AED gradient on the icon, near-black #0F172A wordmark, plain white background. Flat vector, crisp edges, generous negative space, scalable from a 16px favicon to a billboard. Also provide an icon-only favicon version. No mockups, no photorealism, no drop shadows.

Create a logo for a developer tool called "[Company Name]". Build the icon from a stylised code bracket, angle-bracket, or terminal cursor abstracted into one simple recognisable shape. Lockup: icon on the left, the wordmark "[Company Name]" in a monospace-inspired typeface on the right, and the tagline "[Slogan]" small beneath. Palette: dark slate #0F172A background with a single neon-mint #34D399 accent, plus a light-background variant. Flat vector, pixel-crisp at 16–24px. Provide an icon-only version and a horizontal lockup, each in dark and light. No literal laptops or gears, no photorealism, no bevels.

Design a tech-review YouTube logo for "[Channel Name]". Merge a play-button triangle with a subtle circuit-line motif to form the icon. Lockup: icon on the left, the channel name "[Channel Name]" in a clean modern sans-serif on the right, tagline "[Slogan]" small beneath. Palette: cool blue #2563EB and graphite #374151 on white, plus a dark-mode reversed version. Flat vector, sharp and trustworthy, legible as a small avatar. Deliver an icon-only avatar and a horizontal banner lockup. No photoreal gadgets, no gradients on text, no shadows.
