Capture your thoughts today and surprise your future self or someone you love on any date you choose.

In a world of disappearing DMs and endless feeds, meaningful moments get buried fast. We wanted a space where feelings could slow-cook—then arrive precisely when they matter most.
Time Capsule began as a side project between friends who loved writing letters to their future selves. Today it’s a simple tool anyone can use to pause, reflect, and reconnect with the person they’ll become. Whether you’re sending advice, promises, or pure nostalgia, we keep it safe until delivery day. Because some words deserve the gift of time.
