How to let your family use an app you made with ChatGPT
You built a chore chart or meal planner with ChatGPT and want the whole family using it on their own phones. Here's how to put it on a private link with sign-in and saved data.
Some of the most satisfying things to build with ChatGPT are the small apps that run a household: a chore chart, a shared shopping list, an allowance tracker, a meal planner, a packing list for the next trip. The build is the fun part. The frustrating part is getting it off your laptop and onto everyone’s phones. Here’s how to do exactly that.
The quick answer
Connect Backlit to ChatGPT, then ask it to publish your app. You get a private link you can send to the family, sign-in by email so it’s just your people, and saved data so the chore chart still knows who did the dishes tomorrow. No app store, no server, no fiddling.
Why the family can’t use it yet
When ChatGPT builds you a household app, it lives in your browser. To hand it to your partner and kids, three things have to be true that aren’t yet:
- It needs to be reachable. A link they can open on their own phones, not a file on your computer.
- It needs to be private. A family budget or kids’ schedule shouldn’t be open to the whole internet, only the people you choose.
- It needs to remember. Whoever ticks off a chore or adds milk to the list, everyone should see it, today and next week.
Those are the same three gaps every shared app hits. For a family app they matter even more, because the whole point is that several people use it over time.
Putting it on a private link
Backlit is hosting that comes with sign-in and storage built in, and it connects to ChatGPT directly, so ChatGPT can publish for you:
- Connect Backlit once. In ChatGPT, open Settings → Connectors, turn on Developer mode if needed, and add the Backlit MCP server:
https://mcp.backlit.run/mcp. Authorize it. - Ask ChatGPT to publish. In the chat where you built the app, say “publish this on Backlit and let my family use it.”
- Add the family to the allowlist. Your email is on automatically; add your partner’s and kids’ emails so only they can get in.
- Send the link. Everyone opens it on their phone, signs in with a one-tap magic link (or Google/Microsoft), and they’re in.
That’s it: no app to install, no accounts to create beyond an email they already have.
What makes it work for a household
- Private by default. The app requires sign-in and only lets in the emails you listed. Nobody else can reach your family’s stuff.
- Everyone on their own phone. It’s a normal web link, so it works on any phone, tablet, or laptop without installing anything.
- Per-person data when you want it. Each signed-in person can have their own private data (handy for an app where each kid sees only their own chores or savings), alongside shared data the whole family sees, like the grocery list.
- It remembers. Close the tab, come back next week; the data’s still there, pinned to your chosen region.
A few household apps worth building
If you’re looking for a first one to ship to the family:
- A chore chart where each kid checks off their tasks and you see the week at a glance.
- A shared shopping list anyone can add to from the supermarket.
- An allowance / savings tracker with a private balance per child.
- A meal planner for the week that doubles as the shopping list.
- A trip packing list everyone ticks off before you leave.
Each is a single-page app ChatGPT can build in a few messages. Exactly Backlit’s sweet spot.
And no AI inside the app
Worth saying, because it’s the opposite of what people expect: once your family app is live, there’s no AI running in it. ChatGPT did its job when it built the thing. What’s live is a plain, fast, dependable app, which is why it costs a couple of dollars a month at most, not a per-use AI bill. You don’t want a chatbot in your chore chart; you want it to load instantly and just work.
When it’s more than a single-page app
If your household idea grows into something with many screens, accounts beyond your family, or its own server logic, it’s outgrowing Backlit. That’s fine: it means you’ve built something bigger. For the everyday family app, though, this is the whole path: build it with ChatGPT, publish it with Backlit, text the link to the family. See how it works →
