Custom websites & apps
We build websites found by Google and AI.
We build custom websites your customers can find on Google and in answers from ChatGPT, Gemini or Perplexity.
What we do
Our solutions
We build websites and web applications that are fast and ready for AI search, from company websites and web applications to websites for real estate developments. Every website we make can be found by people, Google and AI assistants.

Presentation websites
Responsive websites that load fast and display well on any device. Clear navigation leads visitors to an inquiry or an order.

Websites for real estate developments
A new-build website where buyers pick an apartment straight from the building visualization, view its floor plan and see at once what is still available. The sales team manages availability and prices on its own.

Latest technologies
We work with modern, proven technologies and keep track of where the web is heading. Your website stays fast and secure.

Web applications
We build stable web applications that handle large amounts of data. We design interfaces users understand at first glance.

AI discoverability (GEO)
We optimize websites for ChatGPT, Claude, Gemini and Perplexity: structured data, llms.txt and content that AI can cite, so that it knows about you and recommends you.
Solutions made to measure
AI search
Google is no longer enough
Fewer and fewer people turn to Google; more and more ask AI instead. When someone asks ChatGPT for “the best company in your field”, your website has to be part of the answer. That's exactly what we build every website for.
People ask AI
Millions of users search for products and services every day through ChatGPT, Gemini, Copilot or Perplexity instead of classic search.
AI only recommends what it understands
AI assistants cite websites with clean structure, clear content and structured data. An ordinary website is often invisible to them.
We build it in from the ground up
Every website we build has the technical foundation for AI search built in: from schema.org data and llms.txt to content written so that AI can cite it.
About us
From websites to web apps
We are based in Košice and have been building for the web for more than fifteen years. We built our first websites in WordPress, but over time we moved to our own proven solutions, with an admin interface we designed ourselves around what our clients actually need.
Today we focus mainly on user interfaces for demanding web applications.
We build every project on current technologies and prepare it from the ground up for customers who arrive from Google and from AI.
