What AI website builders do well, and what they don't

AI website builders have become genuinely useful in a short space of time. You can describe a site in a sentence or two and, a minute later, look at something with real structure, sensible type and a layout that works on a phone. That is a big shift from the days when "build it yourself" meant wrestling with a blank template for a weekend.

It is also easy to overstate. We build one of these tools, so we have a clear view of both sides. This post is our attempt at an honest map: what AI builders are good at, what they are not, and how to work with the grain of the tool rather than against it.

What they do well

Getting you past the blank page

The hardest part of making a website is often the first hour. You know roughly what you want, but turning that into sections, headings and a page order is surprisingly draining. An AI builder removes that friction. It proposes a complete first version, and reacting to something concrete is far easier than inventing from nothing.

Even if you end up changing most of it, that first draft has done its job. It has given you a shape to argue with.

Applying sound conventions consistently

A lot of good web design is not invention, it is the careful application of conventions that designers have refined over many years: a clear visual hierarchy, comfortable line lengths, consistent spacing, buttons that look like buttons, navigation where people expect to find it. A well-built AI tool applies these patterns every time, without getting tired or cutting corners at the end of a long day.

That consistency matters more than it sounds. Many homemade sites fail not because of one big mistake but because of dozens of small inconsistencies: three different button styles, headings that change size from page to page, margins that drift.

Speed of iteration

Once a draft exists, trying alternatives is cheap. "Make the header calmer." "Put the prices above the testimonials." "Try a warmer colour palette." Each of these used to mean real effort; now it is a sentence. In Katzero, every version is kept, so you can explore freely and step back if a change does not work out.

This changes how people make decisions. Instead of debating in the abstract, you can simply look at both options.

Cost

For a personal project, a small club, a side business or a portfolio, the cost of a site used to be a genuine barrier. AI builders bring that cost down sharply, sometimes to nothing. Katzero lets you publish on your own name.katzero.com address for free, which means a lot of people who would otherwise have no site at all can now have a decent one.

What they don't do well

Understanding your business from the inside

An AI tool knows what you tell it. It does not know that your customers are mostly nervous first-timers, that your best work comes from referrals, or that one service quietly makes all the money. A good designer finds these things out through conversation and questions you did not think to ask. An AI builder will happily design around whatever assumptions are in your prompt, including the wrong ones.

Original brand thinking

AI builders are strong at assembling well-known patterns into a coherent whole. They are not a substitute for the deep work of building a distinctive brand: a visual identity that could only belong to you, a logo with real meaning, a system that will carry across packaging, signage and print. That is skilled, human work, and it deserves to be paid for when you need it.

Judgement about what to leave out

Good design is often about restraint. A designer will tell you that the fourth section is diluting the first three, or that the page needs fewer words, not more. AI tools tend to be agreeable. If you ask for more, you usually get more. The editorial judgement still has to come from somewhere, and very often that somewhere is you.

Getting the facts right

An AI builder can write placeholder copy, but it cannot verify your opening hours, prices, qualifications or address. Any specific claim on your site needs to come from you and be checked by you.

How to work with the grain

Knowing the strengths and limits suggests a practical way of working.

1. Give it real context. Instead of "a website for my bakery", try "a site for a small neighbourhood bakery that sells sourdough and pastries, open Wednesday to Sunday, mostly regulars, with a focus on pre-ordering for weekends". Specifics produce specifics.
2. Treat the first draft as a proposal. Read it as you would a designer's first round. What feels right? What feels off? Respond to that.
3. Make one change at a time. Small, clear requests are easier to evaluate and easier to undo.
4. Do your own editing pass. Cut anything that does not earn its place. Ask whether a visitor would miss a section if it disappeared.
5. Replace every placeholder. Swap generic text and stock phrasing for your own words, real details and real photographs where you can.

A quick pre-publish checklist

Before you publish, run through these:

• Every fact (hours, prices, contact details, addresses) is correct and current.
• The main action you want visitors to take is obvious on the first screen.
• The site reads well on a phone, not just on a laptop.
• Links and buttons all go somewhere sensible.
• There is no leftover placeholder text anywhere, including the footer.
• You would be comfortable showing it to your most discerning customer.

Where that leaves us

AI website builders are excellent at turning a clear idea into a polished, conventional, working site, quickly and cheaply. They are not a replacement for a designer when your brand is complex, your audience is unusual or the stakes are high. Most people sit somewhere in between, and for them the best approach is simple: let the tool handle the craft it has learned from decades of human design work, and keep the judgement, the facts and the voice firmly in your own hands.
