Using the Prompt Enhancer

AI Generation

Let AI rewrite your rough idea into an optimized, production-ready prompt — for free.

The Prompt Enhancer (the "Improve" button) is one of the most powerful features in THUMBEAST. It takes your rough idea and rewrites it into a detailed, optimized prompt that produces significantly better thumbnails.

How it works

When you click "Improve", your prompt is sent to a specialized AI (Claude) that acts as a world-class YouTube thumbnail prompt engineer. It analyzes your idea and rewrites it with specific details about composition, lighting, colors, expressions, and camera angles — all optimized for the YouTube thumbnail format.

What the enhancer adds

Concrete physical descriptions instead of abstract concepts
Professional lighting terminology (Rembrandt lighting, backlighting, etc.)
Camera lens and framing guidance
Color psychology optimized for click-through rate
Text overlay instructions if text is enabled
Composition based on selected layout template

Info

The Prompt Enhancer costs 0 credits. Use it as many times as you want.

When to use it

Always — even experienced prompt writers get better results with enhancement
When your idea is vague or short ("scary house video")
When you want to explore what the AI suggests for your concept
When using face references — the enhancer integrates face identity instructions
