Boilerplate
Achtung.app is an AI visibility monitoring platform based in Berlin.

The measurement is based on brand-free queries across search-grounded AI platforms with live web search, aggregated into a 0-100 score (AI Prominence). Achtung.app was founded in 2026 by Martin Kulawik and is built in collaboration with Claude by Anthropic.
