🎨 Pro Thumbnail Prompt Gen

Free AI Viral Thumbnail Prompt Generator

Thumbnails are the most critical part of YouTube growth. A high Click-Through Rate (CTR) starts with an eye-catching visual. The SDS Pro Thumbnail Generator helps you create detailed, cinematic prompts for AI image generators like Google Gemini (Nano Banana), Midjourney, or Leonardo AI.

Features of SDS Glow Pro Technology

Our unique "Glow Pro" logic ensures your thumbnails stand out in a crowded feed. Here is how it works:

• Smart Clothing Logic: The tool automatically suggests outfits based on the topic (e.g., Suits for Finance, Hoodies for Hacking).
• Rim Lighting Effect: Adds a professional colored glow (Cyan, Red, Gold) around the subject to separate them from the background.
• 3D Text Integration: Suggests large, 3D text placement for maximum readability on mobile devices.
• Context-Aware Backgrounds: Generates backgrounds that match the video vibe perfectly.

Why Prompt Engineering Matters?

Most people fail with AI art because their prompts are too simple (e.g., "man holding phone"). Our tool expands that into a 50-word detailed instruction covering lighting, camera angle, lens type (8k resolution), and emotional expression.
