On 27 November 2025, the 3rd HÄRTING AI Day took place in Berlin. We spent a whole day focusing on the practical application of artificial intelligence in law firms, companies and organisations – and examined the latest legal developments that those responsible need to be aware of.
The event brought together lawyers, business leaders, compliance experts and tech enthusiasts to provide concrete answers to the question: How can AI be used effectively – and what legal considerations need to be taken into account?
The 4th HÄRTING AI Day will take place on 19 November 2026
The HÄRTING AI Day is back for another edition: the 4th HÄRTING AI Day, themed ‘AI in Legal Practice’, will focus on current issues relating to artificial intelligence, the AI Act, data protection and the practical application of AI in businesses.
