AI credits explained

What are AI credits?

Think of credits as the fuel for your AI builds. Every time you ask the AI to create or change something, it uses credits — and the more complex the change, the more credits it takes. Small text or color changes use around 1 credit, new pages or sections around 2, and larger redesigns up to 10. To put that in perspective, 150 credits is enough to build 2–3 new pages from scratch, or make around 50 individual changes. If you need more, you can upgrade your plan anytime.

What happens if I run out of credits?

On Starter and Plus, your AI builds pause until your credits reset at the start of the next month. On the Unlimited plan, you can build as much as you want. You can upgrade your plan anytime to add more credits.

Does my site, app or tool use credits after it’s online?

No. Once your project is live, it runs on its own on robust IONOS infrastructure. Credits are only used when you're actively building or making AI-powered changes. Your visitors can use your site, app, or tool all day long without touching your credit balance.

Do manual edits use credits?

No. If you click directly into your project and edit text yourself, it's completely free. Credits are only used when you ask the AI to make changes via a prompt. So feel free to fix a label, adjust a headline, or make a quick text change manually without worrying about your balance.

Can I add more credits without changing my plan?

Not yet, but credit top-ups are coming soon. For now, you can upgrade to a higher plan anytime to get more monthly credits.

AI App & Site Builder — FAQs

Do I need coding skills to use the AI app builder?

The AI App Builder is explicitly designed for users with no coding skills. You simply describe your idea in natural language, and the AI App Generator transforms it into a complete, ready-to-use web app or website. It is the perfect solution for anyone looking to build a web app without any technical barriers.

What are credits?

1 credit = 1 AI task.

The more complex the task, the more credits are used. You can use the following as a rough guide: Small changes (color, text) ~1 credit. New pages or sections ~2 credits. Larger changes up to 10 credits. With 150 credits per month, you can, for example, build 2–3 new pages from scratch or make ~50 individual adjustments. If your credits run out, you can upgrade to a larger plan at any time.

How does AI help with building apps without coding?

You can easily build apps without coding by describing your app or website idea using text prompting, voice input, or an image upload. This allows you to create an app with AI without any prior technical knowledge. The AI App Builder automatically converts your description into a working app or website. After publishing, every change is automatically deployed—allowing you to go from idea to app within minutes without dealing with server setup or hosting configuration.

What types of web apps can I create with the AI App & Site Builder?

The AI App & Site Builder generates fully functional web apps and websites—not just static pages or simple templates. Typical use cases include booking tools, internal dashboards, customer portals, or a custom business website. All AI-generated apps are hosted directly on the secure IONOS infrastructure and go live with a single click.

How does vibe coding work with the AI app builder?

Vibe coding refers to an innovative approach where you can create web apps through natural language descriptions rather than traditional programming. With the AI App Builder, you simply use text prompting to describe what your web app should do. The AI translates your description into functioning software without you writing a single line of code, making it easy to vibe code your website and adjust it at any time.

Can I use the AI app builder for multiple apps?

Yes, the AI App Builder is designed to scale with your ambitions, whether you want to create your own web app or run multiple projects simultaneously. Depending on your chosen plan, each project includes an independent web app or website with hosting, an SSL Certificate, and a domain on dedicated IONOS infrastructure. You can upgrade or change your plan at any time.

  • Starter Plan: 1 website or app — ideal for beginners or a clearly defined single venture.
  • Plus Plan: up to 10 websites or apps — suitable for anyone looking to develop and run multiple apps or websites in parallel.
  • Unlimited Plan: up to 25 websites or apps — for larger portfolios or anyone managing multiple projects simultaneously.

Do I own the apps I create with the AI app generator?

Yes, you create your project and are completely responsible for its content. At IONOS, protecting your data is our highest priority. Your app is hosted on our own secure infrastructure and is operated in a fully GDPR compliant manner.
