Webinar: State of Responsible AI
Friday, 5 June 2026, 12:30 - 14:00 CEST, online. Language: German.
A free overview of the most pressing challenges and opportunities of artificial intelligence. We provide orientation and show concretely how to use AI responsibly without compromising on quality.
Production AI we have shipped
Your team asks a question, the RAG chatbot finds the answer in your own documents. The original source is always provided.
We don't just transcribe. Spoken language is turned directly into fully formatted reports, like therapy reports for German Pension Insurance.
Member portal AI
Users find content faster by describing what they need in chat, instead of clicking through categories.
Document triage
Classify and route incoming forms or requests to the right team.
Edit your entire website at once. Translate, adjust tone or check consistency across hundreds of pages at the same time. Before anything goes live, a human approves it.
Our clients and partners
Public sector and municipal administrations
EU AI Act and GDPR compliant. Procurement-ready. Part of the Civic Coding initiative run by the federal ministries BMAS, BMFSFJ and BMUV to advance AI for the public good.
NGOs, associations and impact organisations
Civil society struggles with overloaded teams, full inboxes, and knowledge-heavy member portals with many stakeholders. Many organisations already benefit from our AI solutions. From small associations to leading industry bodies.
SMEs and innovation / operations teams
Prototypes instead of presentations. We deliver working AI prototypes to companies like Kompetenzz and innatura.
Through the development of our Custom GPT, our employees and members can find relevant information much more easily and quickly, and rediscover sources and long-forgotten folders.

AI creates a new kind of intelligence that opens up exciting possibilities for every person and every organization to achieve more. When approached responsibly and with a spirit of curiosity, it can lead to truly great things – as we have experienced when working with N3XTCODER on the AI for Impact Challenge.
