Where apps usually get stuck
The first version of an app is quick: a screen, a list, a button. Then someone asks “can my sister use it too?” and everything changes. Now it needs to know who is who, keep each person’s things apart, and remember all of it after the tab closes. That is the “backend”, and it is where most AI-built apps quietly stop.
What is already there
- Sign-in. Email link, Google, or a fingerprint. No accounts to make, no passwords anywhere.
- Saving. Whatever people add is kept. Private to each person, shared with everyone, or worked on as a team; one switch.
- Live updates. A change on one phone shows on the others in under a second.
- Photos. People can add pictures, and the AI helper can read them.
- An AI helper. Your app can ask AI to summarise, suggest, sort or write, with no keys and no separate bill.
- Nudges and chores. It can send a notification to someone’s phone, and do things on a schedule while you sleep.
How your agent uses it
When your agent is connected to Tiniest Cloud, it knows all of this is there and builds with it, the same way it would build with anything else. You do not have to ask for it by name. Say what the app should do (“a list we both keep, and it tells me when she adds something”) and the sign-in, saving and nudges come with it.
Already built it the old way?
One sentence: “make this app fit Tiniest Cloud.” Your agent rewrites the saving and the sign-in to use what is already there, and the old version stays in case you want it back.
