An AI agent that builds and hosts your site or game
AI can write a website in minutes, then leaves you holding a folder of files. Nox, the AI agent on nox.cool, now takes it the rest of the way: it builds the site, app or game on its own computer, shows you a private preview, and puts it online at its own address when you say yes. Sites can keep sign-ups and accounts without a server, move to your own domain, and games come with a tweak panel and high scores.

Key points
- Ask Nox for a site, a small app or a game: it builds it on its own computer and shows you a private preview before anything is public.
- Approve the preview and exactly that copy goes live at its own address. Every new version asks again, and the last ten are kept to put one back.
- A site can keep RSVPs, sign-ups, visitors' accounts and uploads with no server of its own; you choose who may add, read and change each list.
- A site can move to a domain you already own. nox.cool never buys or registers a domain for you.
- Games play right in the chat with a tweak panel made for each one. Put a game online and it counts plays and keeps high scores.
AI can write a website in minutes, then hands you a folder of files and a list of hosting providers to choose from. Nox, the AI agent on nox.cool, now takes it the rest of the way. It builds a website, a small app or a game on its own computer, shows you a private preview, and puts it online at its own address when you approve. A site can keep sign-ups and visitors' accounts without a server, move to a domain you already own, and a game comes with a tweak panel and a high-score board.
The problem: AI builds it, then you're on your own
Ask a chatbot for a party page, a waitlist or a little game and you'll get code. The hard part starts after that. You need somewhere to host it, a way to put it online, a database if anyone should sign up, a domain, and a way to change one heading without breaking the rest. Most people stop at the folder of files.
That gap is where an agent should help most. Nox already has its own computer in the cloud, where it can write code, run it and look at it in a browser. What it lacked was a way to hand you the result as something you can open, share and keep using. Now the result is a live address.
What can Nox build and put online?
Anything that runs in a browser from a folder of files:
- Websites: a page for a dinner party or a wedding, a portfolio, a launch page with a waitlist.
- Dashboards: a sales board built from a spreadsheet, a tracker that updates when Nox runs its routine.
- Small web apps: a sign-up sheet, an RSVP form, a quiz, a booking request page.
- Games and toys: an arcade game, a puzzle, an interactive explainer.
If an app has a build step, Nox builds it first and puts online what the build produces.
How do I put a site online with Nox?
- Ask for it and say you want it live: "make a page for my dinner party on Saturday, with an RSVP form, and put it live".
- Nox builds it on its computer and checks it in its browser.
- Nox shows a card with a private preview link, what the site keeps, and how many files it is.
- You approve, and exactly that copy goes live at its own address. Nothing changes between the preview you saw and the page your guests see.
Publishing again makes a new version. It asks again (unless you let that site go live without asking), and the last ten live versions are kept, so you can put an earlier one back in one click.

Library › Sites lists everything Nox has published: each site's address, how many visits it had this week, its versions, and buttons to take it offline, download the code or delete it.
Can my site keep data without a server?
Yes. A site Nox builds can keep lists, such as RSVPs, a waitlist, sign-ups or a guestbook, and nox.cool stores them. For each list the site says who may add to it, who may read it and who may change it:
- anyone: any visitor
- signed-in visitors: people with an account on that site
- their own: each visitor sees and changes only what they added
- only you: you, and Nox working for you
The card you approve says in plain words what the site keeps, so you know before it's public. You can be told of each new entry. In Sites, each list is a table you can fix and download as a spreadsheet, and Nox can read it too: "who's coming on Saturday?"
A site can also give its visitors accounts of their own (email and password, for that site only), let signed-in visitors upload files (up to 10 MB each), and even answer them with AI on your account, within a daily cap the site sets (between 5¢ and $20, $1 if not set).
Can I use my own domain?
Yes, a domain you already own. In Sites, add it to the site and you'll see two DNS records to add where your domain is managed: a TXT record that proves it's yours, and a CNAME that points it at the site (or an A record for a bare domain like example.com). nox.cool checks by itself, connects the domain when the records are in place, and gets a certificate on the first visit. The first domain you connect becomes the site's main address.
nox.cool never buys or registers a domain for you. The domain stays in your name, at a registrar you chose.
How do I change one part of a page?
In Sites, Point at a part opens the page with a picker in it. Click the part you mean, such as a heading, a button or a picture, and say what it should become. The request goes to the task that built the site, Nox changes only that element, and the new version asks before it goes live.

Saying "the second button on the left, make it say Join the waitlist" is slow. Clicking it is not.
Can Nox make games?
Yes, and they play right in the chat. Ask "make me a little arcade game" and Nox builds it, tries it on its computer, and drops it into the conversation as a game card. Nobody else can see it yet: it runs at a private preview address, so it needs no OK.
Every game brings its own Tweak panel. The game says which of its settings are worth playing with (ship speed, how many comets a second, gravity, a colour, whether trails are on), and the card turns them into sliders, switches, colour pickers and choices. Drag a slider and the running game changes at once.

When you like what you've got, Keep these settings makes them what every player starts with. Put it online puts that version at its own address, and the card shows the link, how many times it's been played, and the top of the high-score board.

Plays only count on the public address, so your own tries in the chat don't inflate them, and a count is all that's kept: nothing about who played. Scores you set while trying it in the chat stay on their own board. High scores come from players' browsers, so treat the board as being for fun: you can clear it in Sites at any time.
A real example: Snake, start to finish
In one of our tests we asked: "Make me a small browser game I can play right here: a snake game for keyboard and touch, with tweaks for its speed and the size of the grid, and a high-score board."
Nox wrote the game on its computer, played a round in a headless browser to check steering, eating, growing, game over and swipe controls, and put it in the chat. It chose five tweaks of its own: speed (moves a second), grid size (cells per side), whether walls end the game, how much the snake grows per bite, and the snake's colour. We kept our own speed and grid size for every player, put it online, and the plays and scores started counting.
Then we asked for "a green snake and a red apple". Nox changed the files and played the new version into the chat. The older version stayed online, untouched, until we chose to put the new one live.
What keeps you and your visitors safe
- Nothing is public without your OK. A site waits on a card with a preview (unless you've let that one site update without asking); a game stays private until you press Put it online.
- Sites live apart from the app. They're on their own addresses, so nothing a page does can reach your nox.cool sign-in.
- Every version is kept. The last ten live versions can be put back, and any site can be taken offline or deleted.
- No pretending. Nox won't publish a page that poses as another business or person, or asks visitors for card numbers or passwords other than the site's own accounts.
- Little kept about visitors. Visits and plays are a number a day; visitors' own data is kept per site, visible to you, and goes when you delete the site.

Questions and answers
Can Nox build a website and put it online for me?
Yes. Ask Nox to build a site, a dashboard or a small web app and put it live. It builds it on its own computer, shows you a card with a private preview, and once you approve, that exact copy goes live at its own address. Library › Sites lists every site and its versions.
Do I need hosting or a server?
No. nox.cool hosts the site. A site can also keep things such as RSVPs, a waitlist, sign-ups, visitors' accounts and their uploads without any server code of its own: it says what it keeps and who may add, read and change it, and nox.cool does the rest.
Can I use my own domain name?
Yes, a domain you already own. Sites shows two DNS records to add where your domain is managed: one proves it's yours, the other points it at the site. nox.cool checks by itself, connects it and gets its certificate. It never buys or registers a domain for you, so the domain stays in your name.
Can Nox make a game I can share with friends?
Yes. Ask for a game and it plays in the chat straight away. Tweak opens a panel made for that game, such as speed, gravity or colours, and Keep these settings makes them what every player starts with. Put it online gives the game a link that counts plays and keeps a high-score board.
Can I change just one part of a page?
Yes. In Sites, Point at a part opens the page with a picker: click the part, such as a heading, a button or a picture, and say what to change. Nox changes only that element and asks before the new version goes live.
What stops a site from doing something harmful?
Nothing goes public without your OK on a card with a preview. Sites live on an address apart from the app, so a page can't touch your nox.cool sign-in. Nox won't publish a page that pretends to be another business or person, or that asks visitors for card numbers or passwords other than the site's own accounts. You can take any site offline or delete it at any time.

What most AI agents still can't do: five things to check
Most AI agents now share the basics. Five things still set them apart, from what you see before it buys to what a job costs the second time.

What should an AI agent show you before it acts?
An AI agent's approval should show the thing itself: the real page, the price, the email. Why a sentence isn't enough, and how nox.cool built it.

What should an AI agent's screen look like?
An AI agent's app has three jobs: take the task, show the work, ask before anything matters. How we rebuilt every screen of nox.cool around those three.
