Simulate Context Shelf Pop

Never design a thumbnail in isolation on a blank canvas. Toggle between Desktop 3-col and Mobile feeds with competitor decoys to verify that your colors, focal faces, and contrast outshine surrounding videos.

2

Verify Mobile Safe Zones

Over 70% of viewers scroll on phones. Toggle the Mobile Safe Zone overlay to ensure that the bottom-right timestamp badge (`18:42`) or mobile edge crops don't cover critical text elements or facial reactions.

3

Review with Editors Privately

Place critique pins and bounding boxes right over the canvas. Hit Export JSON or Copy Markdown to deliver exact feedback coordinates to your thumbnail designer without paying for expensive review platforms.

Frequently Asked Questions

Do I need to connect my YouTube account?

No. OmniDeck Pro does not require any YouTube OAuth login, channel permissions, or account registration. You can test unreleased video concepts without risking unauthorized access or video leaks.

How does the 10,000 Monte Carlo Bayesian simulation work?

Standard A/B test split calculators often declare false winners prematurely on small click samples. Our in-browser Bayesian engine runs 10,000 random beta-distribution draws based on your recorded impressions and clicks, calculating exact posterior probabilities and 95% credible intervals to determine true statistical significance.

Can I run automated A/B rotation without paying for cloud tools?

Yes. OmniDeck features an autonomous Google Apps Script generator in the Auto-Scheduler tab. You can paste the generated script into your own free Google Workspace account and schedule rotation using Google's official YouTube Data API v3 on a cron trigger.
