Letrune

Read full description

Some words aren't meant to be read right away. Letrune lets you write a letter, choose a future date, and seal it until that day arrives. When the time comes, the recipient unseals it โ€” not with a tap, but with a quiet, ceremonial moment. Write to a friend, a loved one, or your future self. Attach a photo. Choose an envelope. Pick the day it will be opened โ€” tomorrow, next month, or years from now. Then wait. The anticipation is part of the experience. CORE EXPERIENCE Write letters with intention, not speed Choose an Unlock Date โ€” the day your letter can be opened Seal your words in a beautifully crafted envelope Unseal arrived letters with a gentle ritual Revisit opened letters as memories Letrune is not a messenger. It's not email. It's a quiet place where your words wait for the right moment. Terms of Use: https://letrune.com/terms

MessageFuture

Write it today. They open it on the day that matters. MessageFuture is a time capsule for the people you love. Record letters, photos, videos and voice notes, and we deliver them on the exact date you choose, up to 30 years from now. A father records a video for his daughter's wedding day while she is still a little girl. He has no idea when that day will come. If he is there, he delivers it himself. If he can't be, a Guardian he trusts delivers it for him. Either way, she hears his voice on the day that matters most. SCHEDULED MESSAGES Pick the date and time: birthdays, anniversaries, graduations, a first day at university. Your message arrives by email and in the app on the day you chose. TIMELESS MESSAGES Some moments have no date. Write an open-when letter: open when you become a parent, open when you need courage. Write to a child who isn't born yet, or to someone you haven't met. A Timeless message is stored securely for up to 20 years and waits until you release it. GUARDIANS: ALWAYS DELIVERED Add people you trust as Guardians on any message. You stay in charge and deliver it yourself. If you are ever unable to, through illness, an accident or anything life brings, a Guardian delivers it for you, with only the permissions you give. AI TWINS: YOUR STORIES, WHENEVER THEY'RE NEEDED Answer a few questions and create a Twin that chats in your words and tells your stories. Add photos, videos and memories to its library, and it brings up the right one when it matters: a hard week at work, a big decision, a long night. Across time zones, or on the days you can't pick up the phone, your family can still ask what you would say. Add a cloned voice that sounds close to your own. FUTUREME Write to yourself before the exam, the race or the first day, and open it after. Share it if you like: your real nerves, from before you knew how it ended. PRIVATE BY DEFAULT Your messages are encrypted in storage and in transit. Nothing is shared unless you choose to share it. PLANS Start free and schedule up to 5 years ahead. Paid plans add monthly credits and scheduling up to 30 years: โ€ข Standard: $4.99 a month, 50 credits โ€ข Pro: $9.99 a month, 150 credits โ€ข Pro Max: $29.99 a month, 600 credits Perfect for parents, couples, and anyone with something important to say and someone important to say it to.
