We use modern and proven technologies for the best results.
Where our AI solutions are in use
We don't use plugins — we build custom AI systems from the ground up. Real LLMs power our solutions (Claude, OpenAI), yet maintenance costs stay low. The secret: intelligent rule-based pre-filtering handles most requests without an LLM call, forwarding only complex cases to the language model.
Our AI solutions never access the database directly — your product data, business logic and sensitive information built up over years remain completely secure. The AI works exclusively with exported, filtered data. Our webshop AI chatbots know the entire product range and provide personalized recommendations — even based on motorcycle part compatibility.
