From One Sentence to a Live Website: Publishing a Site With an AI Coding Agent

November 11, 2026 · 4 min read

You can go from an idea to a website with a real address without opening a code editor or renting hosting. With Photon, the AI coding agent from SentX SI, you describe the site, a team of AI agents builds it in your workspace, you check the preview, and publishing puts it online at its own address on sentx.site. What follows is one small site taken from the first sentence to the published link, with the checks worth doing on the way.

The example is invented for illustration: a three-page site for a neighbourhood bakery, with a menu, opening hours and an order form. It is not a record of a real build.

Say what the site is for

Start with the result, in ordinary words. "A three-page website for a bakery: home, menu, and an order form that collects a name, a phone number and a pickup time" is enough to begin. One sentence is enough; add files or details when you have them. For a website, the details that pay off are the ones nobody else can guess: your logo, your real menu and prices, your opening hours, the tone you want.

You do not pick a framework or describe a folder structure. Photon takes a request in plain language and returns finished work, not a snippet to paste, and one team of agents carries the job from the plan to the checked result.

Watch the plan, not the code

Once the request is in, a lead agent plans the work and assembles a team of AI agents for it. The agents write, run and check the work in your workspace while you watch the plan and each agent's status. The plan is a list of steps, and that is the level to follow it at. If something you care about is missing from it, the order form for instance, this is the cheap moment to say so.

You can also walk away. Photon asks when a decision is yours to make, and can send a browser notification when a question is waiting or the work is finished. Whether the order form should accept same-day pickup is the kind of thing only the owner knows, and it is better asked than guessed.

Review it like a customer

Finished work arrives in Results, where you open it, preview it, download it or publish it. Websites preview inside the workspace, and a page is visible only to you until you publish it, so the first review happens before anyone else can see the site.

Use that privacy. Look at the preview on a phone as well as a laptop, and do what a customer would do:

• Read every price and every opening hour against your own list.
• Fill in the order form twice, once with a realistic order and once with nothing at all.
• Follow every link in the menu and the footer.
• Look for placeholder text and stock phrases that are not yours.

Whatever is off goes back as a plain message. The Saturday hours are wrong. The form needs a field for allergies. The photo on the home page should be the shopfront. Your files stay in the workspace between sessions, so the team works on the site that is already there, and you review the changed result the same way.

Publish, and know the limits

When the preview is right, publish it. Publishing puts the site's folder online at its own address on sentx.site, and you can send that link to anyone. The address gets an automatic name on the Plus and Pro plans; on Ultra you choose your own.

The limits are comfortable for small sites and worth knowing before you plan a large one. An account can publish up to 25 sites, each up to 3,000 files and 200 MB. A bakery site with a few dozen photos sits far inside that. A catalogue with thousands of product images is a project to size up first.

Keep it current

A site is only as good as its last update. Because the files stay in your workspace, a later change is a new message, not a new project: add the Christmas menu, change the hours for August, swap the photo at the top. Check the preview again, then publish again.

If the same update comes round every week, a specials page for example, you can schedule a message so the recurring work starts by itself. And if you want a ceiling on what any of this costs, set a daily, weekly or monthly spending limit before you begin.

What it takes to start

Photon is part of the Plus, Pro and Ultra plans at SentX SI, and a new account without a paid plan gets a one-time Photon trial. You do not need to know how to code: you describe the result in plain language and judge what comes back. For a first site, choose something small and real, write the one sentence, and expect to spend your time on the review, not on the build.
