Show HN: AI Assistant Widget – GDPR-compliant, RAG-based, 2-line integration

We've been running administrator.de – one of Germany's largest IT communities – for years and kept hitting the same problem: visitors ask the same questions over and over, support doesn't scale, and nobody finds what they're looking for.

So we built this. It's a chat widget that sits on your website and answers visitor questions from your own knowledge base using RAG. You upload text, scan URLs, or add PDFs – the assistant only answers from that. No hallucinations, no generic internet results.

The whole thing integrates with 2 lines of HTML. No SDK, no dependencies. European-only infrastructure – system runs in Frankfurt, models in France, ISO-27001 certified. No tracking, no third-party data sharing. Supports all major EU languages with real-time translation – even if your knowledge base is in a different language.

Every plan includes unlimited conversations. No per-message fees, no per-resolution charges. Pricing is €39–€250/mo depending on knowledge base size. We keep it affordable through a direct partnership with our data center and AI provider.

You can try it live on our product page (chat icon bottom right). Also deployed on https://www.aixit.com – a Frankfurt-based data center provider with 25+ years in the industry. If a company that runs data centers trusts your data handling, that says something.

Happy to answer questions about the RAG architecture, infrastructure, or anything else.
