About Sneak Peek Pro

Sneak Peek Pro – YouTube Thumbnail Preview Tool Sneak Peek Pro lets YouTube creators preview their thumbnails directly inside the real YouTube homepage before publishing. Instead of guessing how your thumbnail will look next to competing videos, Sneak Peek Pro places your image directly into the YouTube grid so you can see it in context. Key features: • Preview thumbnails directly on YouTube • Viewer mode that blends seamlessly into the grid • Click-and-drag positioning and resizing • Keyboard shortcuts for fast iteration • Capture competitor thumbnails for inspiration • Copy thumbnails to clipboard for use in design tools like Canva Sneak Peek Pro is designed to feel invisible — your thumbnail looks like it belongs on the page until you move it. Currently optimized for YouTube. Support for additional platforms may be added in future updates. No data is collected or stored. All processing happens locally in your browser.
