Write one line
A moment, a thought, a feeling. One sentence is all it takes — no long journaling session required.
One line a day.
A chapter of your life every week.
One Line is a simple personal journal: write a few words each day, then let the app turn your week into an intimate, grounded chapter based on what you actually lived.
How it works
The app knows you
You set your context once. One Line remembers it to keep a coherent story — without inventing anything.
Your chapter arrives
Every week, your lines become a personal chapter — grounded, honest, yours to keep or share.
Start now
Your story can fit in one line a day.
