Thumbnail Oracle
Video Preview & A/B Testing
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Stop guessing which thumbnail will get clicks. Thumbnail Oracle lets creators preview
exactly how their thumbnail will look in a real video feed — surrounded by realistic
content cards — before hitting publish.
KEY FEATURES:
FEED PREVIEW
See your thumbnail the way viewers actually see it. Upload your image, enter your
title, and preview it in a pixel-perfect feed card with customizable view counts and
upload timing. Works with any video platform.
A/B COMPARE (Premium)
Can't decide between two thumbnails? Test them side-by-side in a realistic feed
layout. See which one actually stands out before you publish.
COMPETITOR PREVIEW (Premium)
Paste any video URL and see your thumbnail next to real content from other creators in
your niche. Know instantly if your image pops or blends in.
SMART CUSTOMIZATION
Set your channel name, choose view count presets (1K to 10M), and pick upload timing
to see how your thumbnail competes at every level.
SAVE & COMPARE
Save your previews to history so you can look back at what worked and refine your
approach over time.
WORKS EVERYWHERE
Designed for iPhone and iPad. Your thumbnails look great on every screen size.
WHY THUMBNAIL ORACLE?
Your thumbnail is 50% of why someone clicks. Yet most creators just guess. They make
something that looks great in their editor but disappears in the actual feed.
Thumbnail Oracle fixes that. Preview before you publish. Test before you commit. Stop
wasting views on bad thumbnails.
Download Thumbnail Oracle and start making thumbnails that actually get clicks.
