One Line a Day Diary

“One line per day, and show me this date last year.”

The five-year diary format: one line a day, with the same date from every other year sitting underneath it. You don't go looking for last August — you trip over it. A memory tool, honestly labelled as one rather than sold as therapy.

  • Today's line stacked over the same date from up to ten previous years
  • A character limit that's on by default, because the constraint is the safety feature
  • The whole year as one mark per day, so you can see where the gaps really are
  • Jump to any date, fill in anything you missed, and read the lot in one list
  • Exports as plain text that will still open in fifty years

How it works

Three steps, then you're done

Write one line

What happened, or what it was like. Boring is fine.

Look underneath

Last year, and the year before, on the same date.

Save the file

Yours, on your computer, in a format nothing can obsolete.

Nothing you type ever leaves your computer. There is no account, no login and no server. Switch your wi-fi off and it still works — that's not a promise about our policy, it's just how the tool is built.

Questions

Do I need to install anything?

No. Each tool is a single file. Double-click it and it opens in Chrome, Edge, Safari or Firefox — whichever you already have. No account, no password, no software.

Does anything get uploaded?

No. Your numbers and files never leave your computer — the tools have no way to send them and no internet connection is needed to run them. You can switch your wi-fi off and they still work.

I'm not good with computers. Is this too hard?

The first thing every tool does is walk you through it in five short screens with pictures. Then there's a button that fills it with example numbers so you can watch it work before touching anything.

Will it work on my phone?

Yes. Email yourself the file and open the attachment, or drop the files in iCloud Drive, Dropbox or Google Drive and open them from there — then they're on every device you own.
