Seal the moment.
Open it together.
A group time capsule for the moments that matter. Create → invite → contribute blindly → reveal together.
How it works
Three steps to something
worth waiting for.
Create a theme
Every capsule starts with a theme. It could be a weekend trip, a birthday party, or simply "this summer." You set the reveal date and add your own photos and videos to get it started.
Friends contribute blindly
Share an invite link with the people you want involved. They add their own moments, but nobody can see what anyone else contributed. Everything stays sealed until the reveal.
Reveal together
When the countdown hits zero, everyone gets notified at the same time. You all open the capsule together and experience a cinematic reveal of every moment, one after another.
Why Capsl
This is not a photo album.
Your phone already resurfaces old photos for you. An algorithm picks something you have already seen, and you scroll past it. That is passive recall.
Capsl is something entirely different. It is collective discovery. You do not know what is inside the capsule. Your friends contributed moments and perspectives you have never seen before. And when the capsule opens, everyone experiences it together for the first time.
Capsules can be sealed for as little as a few hours or as long as years. A Saturday night out with friends that reveals Sunday morning. A semester abroad that opens on graduation day. A wedding weekend that the couple unwraps on their first anniversary. You decide when the moment is right.
Memories
"Here is a photo you probably forgot about."
- You experience it alone
- Content you have already seen
- An algorithm decides when you see it
- A passing feeling of recognition
Capsl
"10 friends contributed. Nobody has seen a thing. It is time to open it."
- You experience it with the people who were there
- Content you have genuinely never seen
- You choose the moment it opens
- Real surprise, real emotion
The reveal
The reveal is not a slideshow.
It is a premiere.
When a capsule unlocks, you do not see a grid of thumbnails. Instead, you get a fully cinematic experience. Every moment flows into the next with smooth crossfades and gentle Ken Burns effects, while reactions float across the screen in real time. It feels less like scrolling through photos and more like watching a film that your friends made together.

Cinematic reveal
The reveal plays like a short film. Moments flow one into the next with smooth crossfades and gentle motion, not a grid of static thumbnails.
