Triller is an American-based social networking service focused on video sharing. Launched in 2015 for iOS and Android, it initially served as a video editing app before integrating social networking features.

The app offers features such as auto-editing, which automatically synchronizes video clips to the beat of the chosen music, making it easier for users to create engaging content without extensive editing skills. Triller also provides a wide range of music and sound effects to enhance videos.

Users can follow each other, like, comment, and share videos within the app's community. Additionally, Triller allows for cross-platform sharing, enabling users to share their videos on other social media platforms like Instagram, Twitter, and Facebook.

Triller has been used by various celebrities, influencers, and content creators to share entertaining and creative videos with their followers. It has become a significant player in the short-form video space, competing with other platforms like TikTok and Instagram Reels.
