Frequently asked questions
Can AURA also use open-source AI models?
AURA relies on the most capable language models available to deliver the best possible conversation quality. All data is processed in a GDPR-compliant manner on EU servers.
Does AURA have an on-premise option too?
AURA runs as a cloud solution on EU servers. For most hotels, this is the more practical and maintenance-free solution. For special requirements, we are happy to discuss individual options.
How quickly can I switch to AURA?
Setting up AURA usually takes just a few days. Since AURA is set up independently, you can test both solutions in parallel.
