Common questions

Yes. Just describe what you want in plain words; the AI does the rest, and you can see and tweak every step.

No.

Yes. Without signing in you can start talking and the AI really goes to work; you'll see the result run. That part is the real thing, not a demo. Two boundaries worth knowing up front: ① close the browser and it's gone; ② only web-type apps — phone packages, desktop software and database-backed services need you signed in first, because those occupy a real machine and a database that outlive the trial window. When you want to keep the work, or build one of those, sign in once: what you already made comes with you.

You can see it, and you can change course at any point. Every step it takes is listed beside you — which file it read, what it changed, what it installed — and your app sits on the right, updating as it goes. Want a different direction? Just type it; no need to wait for it to finish. That's deliberate: if you only find out at the end whether it's right, this is no different from handing a brief to someone and seeing the result — and most "that's not it" only occurs to people once they see the real thing.

Not once you've signed in: the project and the conversation live on the server, you can pick them up on another computer, and the AI finishes the round it's on even after you close the page. An anonymous trial session, on the other hand, goes away when you close it. Separately, a half-typed sentence on the landing page is kept as a local draft for seven days (on that device only), and we'll ask whether you want to carry on with it next time.

Yes. Once it's in, the platform works out what it is — Go, Python, PHP, Java, Ruby and others are recognised — and prepares a matching development environment (needs Go? you get Go). If it can't tell, it doesn't guess: it says plainly "I haven't worked this one out yet" and tells you which file to add to move on, instead of applying instructions that don't fit your project at all.

Two routes work right now. ①**Make it a web app**: any computer opens an address and uses it — nothing to install, no operating system to worry about, and when you change something everyone sees the new version at once. For most "tools I use on my computer", this road is actually smoother. ②**Make it a command-line tool**: that tier compiles for **Mac, Windows and Linux in a single pass**, each a single file you can copy over and run, no signing needed. If what you want is a windowed Mac/Windows program, then yes — you'll have to wait for us to finish those two. We put that sentence here rather than letting you go through the whole round and discover you're holding a Linux package. And the source is exportable at any time, so you or a friend who compiles can build it on your own Mac or Windows.

Yes, and there are two routes that genuinely work; we'd try the first one. ①**Make it a web app**: open it in Safari on the iPhone, tap Share → Add to Home Screen, and you get an icon on the home screen that opens full-screen. It feels almost like an app, and when you change something everyone sees the new version immediately — no reinstalling. ②**Make an Android build**: for that tier we hand you the .apk directly. The only part that truly needs a Mac is the last step — compiling and signing the Xcode project into something installable on an iPhone. Apple's toolchain runs on macOS only, and nobody gets around that. So we do every step before it and hand you the result, rather than writing "iOS supported" here and letting you find out at the very end.

Absolutely — most people never switch. The moment you publish you have a shareable HTTPS address, free. If you buy a domain later, come back and bind it; links you already shared keep working.

It is. Data is stored against your TutuID, not against a browser or a machine — so a new phone, a new computer or a different browser all see the same thing. And it's not just "still there": add an entry on your laptop and the page already open on your phone updates itself, no manual refresh. We built that on purpose, because "it's on my computer but my phone is empty" is the situation people most often mistake for lost data.

No. Rolling back isn't deleting — your current state is saved as a new version first, then the one you picked is restored. Both still exist, so you can switch again any time. That's deliberate: an undo you can't undo is worse than no undo at all.

Yours. Export the source any time and take it anywhere.
