Sample Output

Here's what the Thumbnail Maker produces

THUMBNAIL CONCEPTS FOR: "I Tried AI Sales Outreach for 30 Days" Platform: YouTube | Niche: B2B SaaS

CONCEPT 1: "The Scoreboard" — Curiosity Gap

Text: "$47K IN 30 DAYS" (primary) / "with AI" (secondary)

Visual: Creator face right-third, wide-eyed surprise. Dark navy background. Stylized laptop with revenue dashboard and green arrow.

Why This Works: Specific dollar amount creates irresistible curiosity. "30 days" implies replicable experiment. Surprised expression (emotional contagion) mirrors the click impulse. CTR Prediction: Very High — number + timeframe + face is strongest B2B YouTube formula

A/B VARIANTS

B (Text Swap): "THIS ACTUALLY WORKED" — tests authenticity vs specificity C (Color Swap): White background — pattern interrupt in dark-heavy feed

Platform Notes:

1280x720px, PNG, under 2MB
Mobile: "$47K" passes squint test at 4 chars
Title says "I Tried AI Outreach." Thumbnail reveals result ($47K). Together = must-click gap.
