Universal Join the waitlist
android first · not out yet · one email when it is

One app.
Ask it to be anything.

Install Universal once. Then describe the app you wish you had — a grocery list that knows your store, a log for the gym, tomorrow's homeschool morning for a 4-year-old — and it appears inside, with its own name and icon, in about a minute.

One email, the day it's on the Play Store. Your address stays on Universal's own server — no lists, no partners.

Ask for an app

Describe the app you wish you had…
Pick one. These four are real: the model wrote them, and they run right here.

Ask for an app

Writing your app

    …

    A replay of the writing, then the real app. Tap around — it works.

    how it works

    Say it. It's written. It's yours.

    01 · say

    Say what you want, in your words

    “A grocery list that remembers what I always buy.” “A log for my workouts.” “Something to plan tomorrow's homeschool morning.” A sentence, not a form.

    02 · written

    A model writes one small, private app

    Against Universal's bridge — storage, notifications, camera, share, export. You watch it come together: structure, look, layout, buttons, memory.

    03 · yours

    Own icon. Own data. Works offline.

    It sits on your grid like any app, and can pin to your home screen. Change it by asking again — your data stays. Didn't like the change? Undo.

    how it feels

    One evening with it.

    The demo isn't the first app. It's the third edit, when you realise the thing is yours.

    7:02 pm
    “Something to plan tomorrow's homeschool morning for my 4-year-old.”
    An app appears: a letter, a number, a story, something outside — each with a box to tick, and a line for how it went.
    7:04 pm
    “Give me three activities for the letter M.”
    It asks the model and lists three. One uses the pipe cleaners you already have.
    An app that can think mid-use is the difference between a checklist and a helper.
    7:09 pm
    “Bigger boxes — she likes ticking them herself.”
    Same app, version two. Tomorrow's plan you'd already written is still there.
    Your data outlives the code. That's the promise that makes it safe to keep editing.
    7:10 pm
    “Actually, I liked the old layout.”
    One tap. Nothing lost.
    Undo is the safety rope. Without it every edit is a gamble.
    7:30 am
    A notification: “Homeschool — story first today.”
    From the same app, on the schedule you gave it last night.
    The moment something it wrote interrupts you on its own, it stops being a demo and becomes software.
    examples

    Real ones. Tap around.

    Each of these is one file the model wrote from the sentence under it. They're running here in the same sandbox they'd run in on your phone.

    what your apps can do

    Small apps with real hands.

    Every app you make gets the same bridge into the phone. That's what separates this from a chatbot that describes an app.

    Remember

    Each app keeps its own data. Change the app; keep the data.

    Remind

    Notifications and repeating alarms, from any app you make.

    Use the camera

    Take a photo into an app: receipts, plants, the whiteboard.

    Share & export

    Send text anywhere, or export a CSV, a file, or the app itself.

    Ask the model

    An app can ask a question mid-use: three activities for the letter M, what to cook with what's left.

    Read each other

    A budget app can read the receipts app. It asks you first, every time.

    Work offline

    Everything except writing a new app works with no signal at all.

    Not yet

    Location, barcode scanning, motion. Coming — not promised for launch.

    privacy & safety

    Small, private, sandboxed.

    Your apps can't reach the internet.

    Each one runs in a sandbox with no network access and a strict content policy. The only door is Universal's bridge, and you're asked before an app reads another app's data.

    default-src 'none'
    connect-src 'none'
    frame-src 'none'
    — the policy every app runs under, verbatim

    Your data stays on your phone.

    Nothing syncs. Nothing is uploaded except the sentence you type when you ask for an app. Back everything up to a file whenever you like, and take it with you.

    Nothing executable is ever downloaded. Universal writes a page and runs it inside itself.
    what it costs

    One subscription. Every app you make.

    what you pay for

    The writing

    The subscription covers the model's time each time you ask for an app or change one. Make as many as you like.

    what's free

    Using them

    Your apps run on your phone. No per-app fees, no ads, and they keep working even if you stop subscribing — only asking for new ones needs the plan. Ready-made apps on the shelf are free to add, too.

    or

    Credits

    Rather not subscribe? A pack of credits for the occasional app. Same apps, same phone.

    Pricing isn't final. The one waitlist email will say, and the people on it hear first.

    questions

    The short answers.

    Is it out?
    Not yet. Join the list and you'll get one email the day it's on the Play Store.
    Android only?
    Android first. iOS once Android has earned it.
    What writes the apps?
    Claude, made by Anthropic. It's included; you never deal with it directly.
    Does it need internet?
    Only to write or change an app. The apps themselves run offline.
    Can it make anything?
    No. It makes small, private apps: lists, trackers, timers, calculators, references, lesson plans, little games. The apps it writes can't sign in to things, take payments, or talk to the internet — by design, not by accident.
    What if the app it writes is wrong?
    Say what's wrong and it changes it, keeping your data. Or undo. And it can't hurt anything — no network, no access to your other apps.
    Is this an app store?
    No. Nothing is downloaded. Universal writes a page and runs it inside itself, so there's no second icon in your app drawer unless you pin one.
    I'm technical. Can I use my own API key instead?
    Yes. Settings has a place for your own Anthropic key; the writing is then billed to you directly and no subscription is needed. Most people never need this.
