✦ Send a message across time ✦
Write a letter, record a memory, or leave a gift — and let it arrive exactly when it matters most.
The ritual
Pour your heart into words. Write to your future self, your children, a friend — or anyone who deserves to receive a piece of you.
Choose when your capsule opens — 1 year, 10 years, or a specific date. Your words are locked away until the moment is right.
On the chosen day, your capsule travels through time and lands in their inbox — exactly as you wrote it, perfectly timed.
For every kind of love
"Open this on your 18th birthday. I wrote it the night you were born."
"For our 10th anniversary. Ten years ago I knew you were the one."
"Read this before your next big decision. You already know the answer."
"Wherever life has taken us — I hope you still laugh the same way."
"This is what I believed when I started. I wonder if it came true."
"If you're reading this, I am gone. But these words are still mine."

What people are saying
I wrote a letter to my daughter to open on her 18th birthday. She's 6 now. I cried writing it.
Used it to send myself a message from 2024 to open in 2034. It felt like time travel.
Sent my best friend a capsule to open on our 10-year friendiversary. She has no idea it's coming.
The email design is beautiful. When it arrived it felt like receiving a real letter from the past.
Simple, free, and it just works. Wrote one to open when I finally launch my startup.
I wrote one to my future self about all the things I'm scared of. Can't wait to read it in 5 years.
