A space where a promise to yourself becomes a record of quietly witnessing one another.
Write your daily intentions in Manifesto. Invite a Witness to quietly watch over your journal, become a Witness for someone you care about, or write alongside a Co-Writer who shares the same stretch of time. Every entry is encrypted and kept as something deeply, enduringly yours. HOW IT WORKS What did you write three days ago? What feeling lingered last month? What did the you from a year ago believe, fear, or hope for? You don’t have to go searching for your past. Yearbound brings it back to you—quietly, and at exactly the right time. 9 Volumes One life, seen through nine lenses: Journal —What from today would you want to meet again later? Growth —What kind of person are you slowly becoming? Gratitude —What precious thing is already here beside you today? Love —Who is resting most deeply in your heart right now? Mindful —In this moment, are you truly here? Letters —Who are your unspoken words reaching for? Work —Where is this work leading you? Abundance —What does “enough” feel like to you right now? Challenge —What effort today will your future self be grateful for? Manifesto Write your daily intentions in Manifesto. They do not need to be long or polished. A single honest sentence, a quiet promise, a hope you are not ready to let go of—those are enough. Over time, these lines become more than notes. They become a trace of who you want to be and what you want to remain true to. Co-Writer Write on the same page together and share time, feeling, and memory. When one person’s record meets another person’s words, something new takes shape—something neither could have made alone. Co-Writer is not only a feature for writing together, but a way of making shared time visible. Witness Invite a Witness to quietly keep watch over your journal, or become a Witness for someone you care about. It does not require many words. Some days, what we need is not advice or judgment, but simply someone who stays near, remembers, and sees us through. Yearbound makes room for that kind of tender connection. Time Capsule Some feelings need to travel farther, to be met again only after enough time has passed. Time Capsule is a place for those moments. Leave a message from who you are now for who you will be later. When it opens again, it may bring back the air of a forgotten season, along with the beliefs, fears, and hopes you once carried. My Yearbound My Yearbound is where scattered entries gather into a single flow. Daily intentions, returned pages, shared writing, and time capsules begin to connect here as one life. It is not simply where records are stored, but a quiet map that helps you understand the shape of the time you have lived. Privacy and Encryption Every entry is protected with end-to-end AES-256 encryption. From the briefest note to the feelings you could not easily show anyone else, your words remain yours to the end. Yearbound is not made for display, but for honesty. Even your most fragile sentence is held quietly and securely in your own time and language.
