oshiparty is a Chrome extension designed to synchronize Amazon Prime Video playback screens between streamers and viewers. Additionally, it displays the YouTube streaming screen and comment section on the Amazon Prime Video website.

To use oshiparty, the streamer first issues a unique URL on the Amazon Prime Video site. Then, the streamer shares this URL in comments on platforms like YouTube Live. Viewers can easily join the synchronized viewing room using the provided URL.

It's important to note that both streamers and viewers must download the extension to utilize its features fully. Furthermore, oshiparty supports seamless continuous playback of episodes without the need to re-issue URLs, enhancing the viewing experience.
