About Picture Party by Myseum

Picture Party by Myseum introduces a new way to make sharing photos and videos easier, a lot more fun, and private. Picture party is much more than a shared album; it’s a complete personal and private social network with a live feed that updates instantly as all your guests’ posts. You can share a post with dozens of pictures, comment and react. It even organizes your photos in an album, or you can relive the Picture Party with all the comments and posts as they happened. Unlike group chats that are unorganized, no matter when you join the Picture Party, you can see everything from the beginning. Picture Party makes it easier and more fun to share with the people right next to you, or anywhere in the world.

Picture Party solves everyday sharing frustrations by eliminating the common headaches of modern photo sharing:

	●	No more passing around your phone for others to view your photos and videos.

	●	No more crowds gathering over your shoulder to see a clip.

	●	No more debating whether to text, drop, email, or tag group photos.

●

No more struggling with social media privacy, data exposure, or AI training risks.

Whether you’re at a family gathering, wedding, sporting event, vacation, concert, school function, or business meeting, everyone becomes a photographer, and no moment is missed. Instantly share group shots without ever chasing people for their copies again.

How it works:

Picture Party lets users instantly create private, encrypted spaces — called Picture Parties — to share photos and videos in curated, personal feeds.

Users can:

	●	Create unlimited Picture Parties.

	●	Invite anyone via text, QR code, or in-app invite.

	●	Launch a Picture Party (a timed or ongoing shared event) in under a minute.

	●	Add titles, comments, and reactions to posts.

●

Maintain complete control over privacy, interaction settings, and who can view or contribute.

Privacy:

The only people that can see your pictures are the ones who you invited to the picture party. All your media and texts are private and encrypted. You decide if pictures can be saved by your guests or who can invite people to the party.

The technology underpinning Picture Party by Myseum is supported by a newly allowed U.S. patent. The patent covers the core personal and private social networking architecture behind Picture Party and represents a significant milestone in Myseum’s intellectual property strategy. The Company believes the new IP is foundational to a new category of private social interaction and a key driver of long-term platform value.
