Two siblings, one ageing parent, and a medication list that lives in somebody's phone photos. The sibling who happens to be at the appointment reconstructs the history from memory. The other one finds out afterwards, in a message thread that nobody can search.
Care for a parent is usually shared. The paperwork usually is not. Here is a way to put it in one place that each of you can ask — from your own AI assistant, whichever one you use.
Make a space for the care, not for the family
Create a shared space named for what it is: "Mum's care". Invite your siblings by email. They need a justonce.ai account first, which is free, and they join the space free. Give the sibling who does most of the appointments the Editor role; the others can start as Viewers and share their own memories in.
Your personal vault is never part of this. A space holds only what someone deliberately put in it.
Put the documents in through your assistant
Nobody wants to type out a discharge letter. Attach it to a message to your connected assistant and paste this:
Mum's discharge letter is attached. Save the medication changes, the follow-up date and the cardiologist's name to JustOnce as separate memories, keep the letter attached, and share all of them into the "Mum's care" space.
Your assistant reads the letter with its own vision — JustOnce runs no OCR, by design — and writes the facts as separate memories, so each one is recallable on its own. For the letter itself it gives you a one-time upload link; open it, pick the file, and the original is attached, encrypted, to those memories. Because the prompt says "all of them", every memory reaches the space, not only the one the file hangs off.
Do the same with the medication list, the specialist's card, the insurance details, and who holds power of attorney. Everything is filed into its category — Health, Legal, Insurance, Family — with the dates and names inside it extracted.
The next appointment
The sibling at the next appointment asks their own assistant:
What changed in Mum's medications at the last discharge, and who is her cardiologist? Tell me who saved it, and pull up the letter.
The answer comes back from the shared space, attributed to whoever saved it. Asking for the letter fetches the original over the authenticated connection, or they open it from the space in the web app. No public link to forward, no folder to hunt through, and every fetch is logged.
When things change
Arrangements change. The Owner can remove a member, and closing the space revokes everything it granted. Nothing anyone shared is deleted — it stays in the vault of the person who saved it.
What this does and does not do
- Recall is real, and scoped. Each sibling's assistant recalls shared memories when it searches, attributed to the sharer and read-only. Topic briefings and core profiles still draw on each person's own vault.
- Documents travel with memories. A file always lands in the uploader's own vault first; sharing the memory is what lets a member fetch it. A member sees exactly the memories shared, which is why the prompts above say "all of them".
- Pages are metered once, against whoever saved the document. Reading and fetching cost nothing, on any plan.
- There is no reminder or notification feature. If you want to be told when the follow-up date arrives, ask your assistant to check the space at the start of a conversation; JustOnce will not message you about a date.
- Encryption is specific, not magic. Documents are encrypted at rest under the uploader's key, memory bodies under a key for the space, and nothing is used to train models. Search runs over decrypted text inside our service, under keys we hold, so that search works; this is not end-to-end encryption.
The household paperwork use case has the same prompts for insurance, rating plates and school forms, and the sharing page lists exactly what a shared space does today.
