Perfect for YouTubers who want to know which thumbnail performs better before publishing.

- Upload two thumbnails and compare them alongside real YouTube-style content
- Three view modes: search results, recommended, and mobile
- A/B labels visible in the preview
- 100% local, no data is sent anywhere
