A digital time capsule you keep open: how to save the moments that shaped you
A time capsule is a box you bury and dig up twenty years later. It holds what someone thought was worth keeping on one particular day. Most of it is a surprise when it comes back, and much of it means little.
A life is better kept the other way round. Not everything from one day, but a few days from everything: the moments that changed something, gathered from childhood to last week, and open whenever you want to look. That is what Lifeline is for.
Not a daily diary
If you have ever started a diary and stopped after a few weeks, you know why. Writing every evening turns into a duty, and most days are like the day before.
Lifeline asks for something else. It is a place for the days that mattered: the first steps, the move, the wedding, the diagnosis, the call that changed your plans, the day you lost someone. You may add a memory twice in one evening and then nothing for a month. There is no streak to keep and nothing to fall behind on.
A good test for whether something belongs here: would you want to find it again in ten years? Lunch, no. The lunch where your friend told you she was leaving the country, yes.
Start with the past
Most of the moments that shaped you happened before you had any app. That is the right place to begin. A memory in Lifeline can be dated any day back to 1900, so the line can start where your life starts, or earlier, with a story your grandmother told about hers.
If you don't know where to begin, go decade by decade and ask yourself a few questions:
- What is the earliest thing you remember?
- Where did you live at ten, and what did the place smell like?
- Who was your closest friend at fifteen, and how did it end?
- When did you first feel like an adult?
- What decision would you make differently, and which one would you make again?
- When did you last laugh until it hurt?
You don't need the exact date. Pick the day you think it was, the first of the month or of the year. What matters is the order, and that the moment is saved before more of it slips away. (Why the details go first, and the gist stays, is a question with a real research answer: why memories fade.)
What to keep in a memory
When a memory comes back to you, it rarely comes back as a sentence. It comes as a face, a voice, a song from the car radio, the light in a room. So a moment in Lifeline can hold more than words:
- Photos and a video from your gallery, including scans of old paper photos.
- A voice note. Tell the story out loud the way you would tell a friend. In twenty years your own voice from today will be part of the memory. If you'd rather read it, tap "To text": once you've agreed to AI features, the recording is sent to the AI and its text is added to the memory.
- The song that was playing, from Spotify.
- How it felt: an emotion, a word of your own for it, and how strongly you felt it. A stronger moment looks larger on the line.
- The words: a few sentences or several pages. Write the details you'd otherwise lose: who was there, what was said, what you were afraid of, what happened next.
The present: only what has weight
Lifeline works for today as well, with the same rule. Keep the conversation after which you felt understood, the evening a child said something unexpectedly wise, the morning you decided to quit. Leave the routine out. If you only write when something matters, everything you have written will matter.
One line, from decades to a single day
All your moments sit on one line. Zoom out and you see decades at once: the busy years, the quiet ones, the places where the line turns. Zoom in and the years open into months, weeks and days, down to a single memory. Long empty stretches are drawn shorter, so a quiet decade doesn't push everything else off the screen.
This is the part a diary can't give you. Read one entry at a time and you see one day. Look at the whole line and you see how one thing led to another: the job that came from a chance meeting, the move that followed a loss.
When you need a specific memory, search finds it by its title, words, date or feeling (the words of locked memories are not searched), or you can jump to any day.
On this day
Each morning Lifeline can bring back what happened on the same day in earlier years. It is the open time capsule: no waiting twenty years, a little of the past every day, when there is something from this date.
You decide what comes back. Sad memories can stay quiet with one switch, and any memory can be told never to return. It is your past, and some days are better left where they are.
Questions, when you want them
Writing about a moment, it is easy to stay on the surface: "It was hard." A few good questions help you see it again. If you want them, an AI can ask some about a memory, and with Premium it can notice what keeps coming back across a month, or write a short Life Compass from your recent memories.
AI in Lifeline is optional. Nothing is sent until you agree once; after that, each feature sends only what it needs, through our server, to Google's Gemini model. One switch turns all of it off, and there are switches of their own for questions, for monthly patterns, and for the Life Compass with "What followed similar moments"; everything else runs only when you tap it. Background features never send the text of a locked memory; questions on a locked memory are sent only after you confirm. The app has a screen called "What the AI sees" that describes what each feature sends.
Lock what is only yours
Some memories you would never want anyone else to read. Lock a memory with your master password and its words (the text, your reflections, the AI's questions and your answers) are encrypted on your phone with AES-256-GCM before they reach our server. We can't read them.
To be precise about what that covers: the title, date, emotions (including the word you choose for the feeling), the song, photos, videos and voice notes are not encrypted. Keep your recovery key when the app shows it: without it, a forgotten password means the locked memories can't be opened again.
Yours to take with you
A record of your life shouldn't depend on one company or one phone. Export is free: one ZIP archive with every memory as text, plus your photos, videos and voice notes, or a PDF of a single memory to print or send to someone.
How to start tonight
Give it fifteen minutes. Add three memories:
- The earliest one you have. However blurry.
- A turning point. A day after which things were different.
- Something from the last month that you'd want to find again.
Three points already make a line. Tomorrow morning, look at it from far away.
The free version has no ads and export is always free. Premium removes the limits on photos, videos and voice notes and adds the deeper questions, the pattern of the month, the Life Compass and "What followed similar moments". If you have no income of your own, or simply can't afford it, write to founder@theplacewelive.org and we'll work something out.
