Let your own agent keep your parent's paperwork, share one space with your siblings, and let each of them ask whichever assistant they've connected, or open the space on the web, instead of asking you. JustOnce keeps the records your parent is happy for you all to know. It doesn't give health advice, and it should only start after your parent says yes.
"Dad ops"
Carers have their own words for this. Someone looking after their father summed up their week in a five-star App Store review of Grok Bot on 30 September: "…am the primary care giver for my 84 year old father. Bottom line, I am managing church ops, dad ops, and my personal life." On Hacker News on 9 October, someone with ageing parents put it more bluntly: "I am the agent for them every time they call frantically for help." (Both re-read 26 October 2026.)
What makes it heavy is usually not any single task. It's that one sibling ends up holding everything: which letter came from which department, when the next appointment is, what the council rates notice said, where the power of attorney lives. Everyone else has to ask that person. And everyone asks a different assistant, because the eldest uses Claude, the middle one uses ChatGPT and the youngest uses Gemini.
Talk to Dad first
Before anything goes in, ask him. Explain what you want to keep, who will see it, and that he can say no to any of it. It's his paperwork and his privacy. Agree on a short list together.
Some things are better left out entirely:
- Passwords, PINs and security answers.
- Full card numbers.
- Anything he'd rather keep between him and one of you.
If he'd like to see what's there too, invite him to the space. He doesn't need an account first.
How do I set up a shared space for Dad's paperwork?
Shared spaces come with Plus and Pro: Plus includes 1 shared space and Pro includes 3; Free is your personal space only. Whoever sets it up owns it; everyone else joins free.
Sign in to the web app, open Spaces, choose Create space and name it for what it is: "Dad". Then open it and choose Invite member for each sibling.
- No accounts needed. Invite anyone by email — no account needed. They create a free one, then accept. An invitation lapses after 30 days.
- Pick roles. Make the sibling who handles most appointments an Editor, so they can correct shared records. The others can be Viewers. Any member can still share their own memories into the space.
- It's free for them. Members join free, and recall and search are always free, on every plan.
Your own memories never become part of this. A space holds only what someone deliberately shares into it.
Snap and save the letters
When a letter arrives, photograph it and hand it to your assistant with one prompt:
Read this letter about Dad's hospital appointment. Save the date, time, place, department and reference number to JustOnce, keep the photo with them, and share them into our "Dad" space.
Snap it, and your AI reads it and saves the facts; the original photo is attached. JustOnce runs no OCR, so your AI does the reading. Photos can be JPEG, PNG, GIF or WebP, and files up to 25 MB, including PDFs.
The save happens straight away. The share into "Dad" waits for you: when your assistant asks to share something or invite someone, nothing is shared or sent until you approve it in JustOnce. Your assistant gives you a link; open it signed in, check the list, and approve, and we ask you to confirm it's you. It expires after 24 hours.
The same works for the pension letter, the rates notice, the pharmacy's printed list of his medicines and the power of attorney. Keep it to records. JustOnce remembers what the paper said; it doesn't interpret it, and the answer is only as current as the last letter someone saved.
Can my siblings ask their own AI about Dad's appointments?
A week later your brother asks his assistant, "When is Dad's next hospital appointment, and what's the reference number?" Each member's own assistant recalls what's shared with them, credited to the person who shared it, so the answer comes back with your name on it. The credit is your display name, or your email address if your account has none, so he knows who to ask if something looks off.
As of 26 October 2026, JustOnce works with Claude, ChatGPT (Business, Enterprise and Edu), Cursor, VS Code, Gemini CLI, Codex and Claude Code. On ChatGPT Pro your assistant can read your memory but not save to it. The Gemini app isn't connected yet. A sibling whose assistant isn't connected opens the space in the web app and reads the same records. Share the memory a file is attached to and the file goes with it — members open it in the web app.
When things change
Appointments move and letters get superseded. When a detail changes, ask your assistant to correct the existing memory rather than save a new one:
In JustOnce, update the memory about Dad's cardiology appointment: it has moved to 14 November at 10:30. Keep the history.
Corrections keep the old value, so you can still see what the old letter said. If you saved the record, your siblings' assistants recall the corrected value the next time they ask. If your sister saved it, she's best placed to correct it. An Owner or Editor of the space can correct it too, through their own assistant or the web app, and every sibling's assistant recalls the corrected version from then on. Looking back over a record's history works for the person who saved it. The history post goes into this in more detail.
Who can see what, and how do I close the space?
- Members see only what's shared into the space. Each sibling's own memories stay private.
- Owners and Editors can correct shared records; Viewers read them. Only the person who shared a record can erase it.
- Closing the space ends every member's access. Only the owner can close it. The memories stay with the people who saved them.
- Forgetting is permanent. Forget means gone — there's no restore.
- Encryption, plainly. Encrypted at rest with AES-256-GCM — memories under a key for their space, documents under a key for your account. JustOnce holds the keys, so it isn't end-to-end.
Care is shared work. The paperwork can be too. Our earlier guide to keeping a parent's paperwork in one place covers what to put in, and the sharing page covers roles and closing a space.
