How to build a website with AI: a step-by-step guide

Short answer: pick an AI builder that matches your project, write one detailed prompt that describes your users, pages and data, build one feature at a time, test on a phone, then connect a custom domain and check that search engines can read your pages. For most non-coders, Base44 is the fastest place to start.

Step 1: decide whether you need a site or an app

This one decision picks your tool. A site is pages people read: a portfolio, a landing page, a company website. An app is something people log in to and use: a booking tool, a client portal, a dashboard, a small SaaS product.

• Marketing site: use Framer. It produces the best-looking pages and you will not pay for a backend you do not use.
• App with logins and data, and you cannot code: use Base44 or Lovable. Both build the database and accounts for you.
• You can code: use Cursor, Bolt or v0 for direct access to your code.

Not sure? Our AI website builder comparison puts all seven options side by side.

Step 2: write the first prompt like a brief

The first prompt sets the structure of everything that follows, so spend ten minutes on it. Vague prompts produce generic results that take many credits to fix. Include five things:

1. Who it is for. "Independent yoga teachers who run small classes."
2. What they need to do. "Students book a class, pay, and get a reminder email."
3. The pages or screens. "A public schedule, a booking page, a student account page and an admin view."
4. The data. "Classes have a date, time, capacity and price. Bookings link a student to a class."
5. The look. "Calm and minimal, lots of white space, one accent color."

Leave out features you do not need for launch. Every extra feature in the first prompt adds code the AI has to read on every later edit.

Step 3: build one feature at a time

Once the first version exists, change one thing per message: "add a waiting list when a class is full", not "add a waiting list, discounts, and a new color scheme". Small requests are easier for the AI to get right and easier for you to check.

When something breaks, describe what you expected and what happened instead, and paste any error message. If a fix makes things worse twice in a row, roll back to the last working version rather than piling on more prompts. Most builders keep a version history for this.

Step 4: watch your credits

AI builders charge in credits or tokens, and the free plans are for testing, not finishing. Costs rise as the project grows, because the AI reads more on each edit. Two habits help:

• Plan your next few changes before you prompt, so each message does real work.
• Make small text and color tweaks in the visual editor when the builder has one, instead of spending AI credits.

On Base44, also note there are two meters: message credits for building and integration credits that your live app uses. Read our Base44 vs Lovable comparison for how the plans differ.

Step 5: test like a real user

Before you share the link, go through the main task as a stranger would, on your phone. Sign up with a new email, complete a booking or purchase, and log out and back in. Check that the empty states make sense, that forms show useful errors, and that a non-admin user cannot see admin pages.

Step 6: connect your domain and go live

A custom domain makes the site look trustworthy and is better for search. Buy the domain from any registrar, then follow your builder's domain settings to point it at the app. Base44 includes custom domains from its entry paid plan. Lovable, Bolt and Framer also need a paid plan for a custom domain.

Step 7: make sure Google can find it

An AI-built site can rank well, but only if search engines can read it. Check four things:

1. Pages are prerendered or server-rendered. Base44 serves prerendered pages to crawlers. Bolt charges extra for prerendering.
2. Each page has a unique title and description that says what the page is about.
3. You have a sitemap and you have submitted it in Google Search Console.
4. The text is real text, not words baked into images.

Common mistakes to avoid

• Starting with the design before the data. Get the structure right first, then style it.
• Asking for many changes in one prompt.
• Ignoring lock-in. If you may need to move the app later, check code export before you commit.
• Launching without testing sign-up and payment as a new user.
