How to Share One AI Assistant With Your Whole Family
Updated: 1 day ago
Most families have one person who "does the AI stuff". They draft the difficult email, look up the recipe substitution, decode the insurance letter. Everyone else sends their questions to that person.
It works until that person is busy, asleep or on a plane. The better arrangement is for everyone in the family to have the same assistant, and the easiest way to do that is to give it a phone number.
How unevenly AI is spread inside a family
Pew Research Center's 2025 ChatGPT survey, fielded February 24 to March 2, 2025 with 5,123 US adults, gives the share of each age group that has ever used ChatGPT:
Ages 18 to 29: 58%
Ages 30 to 49: 41%
Ages 50 to 64: 25%
Ages 65 and over: 10%
We used those four numbers to model a simple family: one adult child in their twenties, one parent in their forties, one grandparent over 65. We treat each person's chance of having used ChatGPT as their age group's share and assume the three are independent, which is a simplification, since families share habits. The results:
Chance that at least one of the three has used ChatGPT: 1 minus (0.42 times 0.59 times 0.90), which is 78%.
Chance that all three have: 0.58 times 0.41 times 0.10, which is 2.4%.
Chance that only the youngest has: 0.58 times 0.59 times 0.90, which is 31%.
Chance that neither the parent nor the grandparent has, regardless of the child: 0.59 times 0.90, which is 53%.
So in roughly four out of five families with these three generations, the AI is already in the house. In fewer than one in forty, everyone has it. The most common single outcome is the one you would guess: the youngest person has it and nobody else does.
The older half of the family is interested, not opposed
It would be easy to read the 10% figure as disinterest. AARP's 2026 Tech Trends report, a survey of 3,838 adults run September 9 to October 6, 2025, says otherwise for the 50 and over group. Among them, 19% use AI platforms such as ChatGPT or Copilot, 21% are interested in them but not using them, and 59% have no interest.
The interested-but-not-using group is slightly larger than the group that already uses them. That is the group a family can reach. AARP also reports that texting is now the leading communication method among adults 50 and over, and that three in five say technology is not designed with their age in mind. An AI that arrives as a text message is designed around their habits by default.
Pew's survey adds one more reason the gap matters: 26% of US adults have used ChatGPT to learn something new. The grandparent with a question about a plant disease or a Medicare letter is exactly the person that number describes, and exactly the person least likely to have the app.
What sharing it actually involves
With Assistant Textapp, the assistant is a phone number: (518) 302-2982. Sharing it is forwarding a contact. There is no family plan to set up, no shared login, no app to install on each phone. Each person texts from their own phone, and each person gets their own conversation and their own memory. Your mother's questions are not visible to you and yours are not visible to her.
Here is what it looks like across three phones on the same afternoon:
Grandparent: my tomato leaves have yellow spots with brown edges, what is it
Assistant: Most likely early blight, a common fungus. Remove the spotted leaves, water at the base rather than from above, and keep the plants spaced so air moves. A copper fungicide helps if it keeps spreading.
Parent: reword this so it sounds less annoyed: "As I said in my last three emails, the invoice is still wrong"
Assistant: "Following up on the invoice. It still shows the earlier amount. Could you send a corrected version when you have a moment?"
Adult child: whats the difference between a roth and traditional ira in one sentence
Assistant: A traditional IRA is taxed when you take money out, a Roth is taxed going in and tax-free coming out. Which is better depends on your tax rate now versus later, so it is worth checking with a financial advisor before choosing.
Each person can ask for more to get a longer answer, and tell it to forget what it remembers about them. For medical, legal or money questions it gives general information and says to check with a professional, which is the behavior you want in something your whole family uses. It also cannot act in the world. It will not pay, book, call or send anything, so nobody in the family can accidentally commit to something through it.
A simple rollout
Save the number on your own phone and text Hi. Use it for a day so you can explain it in your own words.
Forward the contact to each family member with one line: "Text this number any question. It answers like a person. Ask for more if you want detail."
For the relative who is least likely to try it, send the first question with them, in person or over the phone. Pick something they actually want to know.
Leave it alone. The assistant works best when people use it for their own questions rather than the ones you think they should ask.
The first 20 messages are free for each phone that texts it, so everyone gets a real trial without anyone paying. After that, one $9.99 a month subscription covers every Textapp.
Why a number beats an account
Shared accounts fail for a reason: one password, one history, one person's preferences applied to everyone. A phone number has none of that. It is the one identifier every member of the family already has, from the adult child to the grandparent with the flip phone, and it is the same one they use to reach each other.
Try it by text
Text Hi to (518) 302-2982 to start Assistant Textapp, then forward the number to anyone in your family. It works on any phone that can text, with no app and no account. The first 20 messages are free. After that, one $9.99 a month subscription covers every Textapp.
