A cute journal app with no stickers to buy. In Prubi, masking tape, ribbons, a date stamp and pixel friends open one by one as the days you write add up, and your desk takes on your own look.
Prubi
Prubi is an AI-powered cloud note service and Personal Wisdom OS. Save your notes, photos, documents and schedules in your own private account, and let Prubi AI help you retrieve past records, organize what you wrote today, and review the schedule you saved for the days ahead. Free and paid subscription plans are available.
Sensitive records — passwords, account numbers, a photo of your ID — go in the personal vault. Entries and their attachments are encrypted on your device with AES-256-GCM before upload, so the server keeps only ciphertext plus the salt and IV needed to decrypt it. The key is never stored, so what the server holds cannot be read on its own; if you forget the vault password, only a recovery key you made in advance can reopen it.
No stickers to buy. As the days you write add up, masking tape, ribbons, a date stamp and a small friend who walks across the screen open one by one.
A decorated desk and the stationery box, with pixel friends that open as you write
The stationery box — tape, stamps and friends
Nothing to buy and no random draws. Stationery opens as your recorded days add up, and a few days off never take back what you already have. Pick the pixel friend you like and it walks along with you.
Prubi decorates the desk and the screen, not the writing itself. Choose the paper, the tape and the little props for your own desk, and what you write on it stays clean and simply yours.
Decorate your desk — Open the stationery box from the desk on Home.
Today's line — Open today's box and write one line. That's all.
What you wrote before — Find it again by date, or by folder.
There is more stationery, and more friends, than are shown here. Seeing them all in advance would spoil the day each one opens, so they are better met as you write.
What it is, how to start, and what to know beforehand each live in their own place.
