Six7 is a Chrome add-on designed to enhance the YouTube experience by enabling private direct messaging during live chats. Users can engage in private conversations with others in the same YouTube room without the need to share their personal contact information. This feature is particularly useful for maintaining privacy while participating in live chats or replays, allowing for quick and spontaneous discussions among viewers.

In addition to private messaging, Six7 offers a straightforward peer-to-peer file sharing option. Users can easily send files by clicking the paperclip button, with the transfer occurring directly between peers without relying on server-hosted storage. This add-on is free to use and provides a secure environment for temporary room-based sessions, making it a valuable tool for those who frequently engage in YouTube live interactions.
