Keep and share your memories forever.

A place to keep what matters and share it on your terms — built on plain files you own, that stay readable long after any app is gone.

№ 01 The gap diaryx.org / why

Preservation and sharing should go together.

Things that last

Backup drives, archive boxes, institutional repositories. Decades of survival, but hardly anyone sees them.

Things people read

Feeds, photo apps, blogging platforms. Everyone sees, but it might not be there tomorrow.

gets read lasts backup drives archive boxes photo apps social feeds Diaryx

Diaryx is the one artifact that does both: kept like an archive, shared like a letter.

You might be the last person to recognize them.

Diaryx helps you attach names, links, transcripts, and more, ensuring that your memories are not forgotten after you are gone.

№ 02 Sharing audience: — who may read this

One entry. Four different readers.

The reason archiving doesn't usually go hand-in-hand with sharing is because archives often contain sensitive information. Diaryx allows you to define "audiences" as a form of access control, so you can share with confidence.

Pick a reader and watch the same entry change.

And publishing is opt-in: until you share something, your data never leaves your device.

Everyone

We drove out to the coast before sunrise. The fog didn't lift until nearly ten, and then all at once the whole bay was there.

Friends

Sam brought the thermos that leaks. We laughed about it for an hour and drank cold coffee anyway.

Family

Dad would have loved this stretch of road. I keep catching myself about to call him about it.

Just me

I'm not as okay as I've been telling everyone. Writing it here because it needs to be written somewhere.

A Papers Project of your own.

If Diaryx vanished tomorrow, you would lose nothing.

Diaryx is modelled on how archivists actually work — it borrows its data model from the professions that formalized this decades ago. See how Diaryx keeps your files durable, safe, and accessible.

Every entry is a plain Markdown file with YAML frontmatter, in a folder you pick. No database, no proprietary container, no export button to hunt for — a text editor from 1985 or 2055 can open your journal.

The same entry in Diaryx: the title set as a heading, the frontmatter replaced by People, Places, and Tags fields, and the body laid out for reading. In Diaryx
The same entry open in TextEdit: YAML frontmatter with title, id, part_of, audience, and dates, followed by the journal entry as plain text. The file itself

Drag the divider — it's the same file on both sides.

You pick where the folder lives — iCloud Drive, Dropbox, Syncthing, a Git repo. Diaryx doesn't need to be the one syncing it, and if Diaryx vanished tomorrow the files would still be sitting there, readable.

The format is documented and open — even without us, your vault stays readable by something.
№ 04 Pricing free, plus $4.99/mo to publish at scale

The app is free. You pay only to publish at scale.

Writing, audiences, views, fixity, the whole archive — all of it works offline and costs nothing. Diaryx Plus exists because hosting other people's reading is the one part that costs real money.
