Write one line a night. Keep the day.
Keepsake is a private notebook for what actually happened — yours, and shared only with the one or two people who were there.
They write their line about the same evening, so you get back more of it than you wrote.

248 days slipped past already — 117 still yours, starting today.
How it works
Share the day with whoever was there
They write their own line about the same evening. You get back the half of it you didn't write down — and their photo of it.
Watch the year fill in
Every day you keep darkens a square. The shape of your year, before you read a word of it.
Yours, and only yours. No feed, no algorithm, no ads. Just the days worth keeping.

What one line looks like.
One day. One sentence. Written that night.

Long call with Dad tonight.
He just wanted to talk.
I'd been putting it off all week.
Really glad I picked up.
Four lines, twenty seconds, and the day is yours. Not the gist of it — the actual evening.
A photo proves it happened. A line tells you how it felt — and that's the part you actually want back.
The half of the evening you didn't write down.
You
Had a few people over for dinner.
Nobody wanted to go home.
Stayed up talking long past midnight.
J.
Dinner at yours. I brought dessert.
We laughed about the old days.
Didn't want the night to end.
Share a day with the one or two people who were there and you each write your own line. You end up with more of the evening than you wrote.And their photo of it — the one you weren't holding the camera for.
What 20 seconds a night actually does.
Three things, and none of them small.

Your week feels twice as long.
People who note a new experience later estimate that twice as much time has passed. The brain, given a marker, stretches the day around it.

You get back a quarter more of the day.
Putting words to what happened, even briefly, increases the number of distinct memories you can later recall.
Pennebaker & Seagal, 1999

Your sleep finishes the job.
A few sentences before sleep strengthen how the day consolidates overnight. The same week, recalled with more texture.
Walker, 2017
Not every day. Just the ones you'd want back — and now you have them.
Write down today. Keep it for as long as you want it.
