Why Achtung.app exists
When a potential customer asks a question today, they don't necessarily go to Google. They ask ChatGPT, Perplexity or Gemini. The answer either names a brand or it doesn't — and the rest of that answer shapes their decision far more than the ten organic results below it.
Classic SEO tools measure rankings inside result lists. They don't measure whether an AI model recommends a brand on its own. Achtung.app closes that gap: daily, blind measurement of brand mentions in AI answers; across multiple search-grounded providers (live web search per query); brand-free queries; a 0–100 score.
I needed this measurement for my own marketing projects, and I wanted a tool where I know exactly what it does — which prompts, which models, which aggregation steps. A handful of comparable tools exist (Profound, Peec.ai, Otterly), but none of them combines search-grounded methodology, a DACH focus and openly documented data provenance. That combination is what I was looking for. Achtung.app is the answer.
What Achtung.app measures — and what it doesn't
Achtung.app measures whether AI models name, cite or recommend a brand when someone asks a relevant question — without including the brand name in the query. From the answers it derives a 0–100 score (AI Prominence), a mention rate per provider, a list of third-party sources the AI pulls in, and a per-keyword gap analysis.
Achtung.app does not measure:
- Mentions in social media or classic news (tools like Brandwatch, Meltwater, Talkwalker do that).
- Classic search-engine rankings (Semrush, Ahrefs do that).
- The quality of your content. Achtung.app shows what AI does today with the data available about your brand, not whether your copy is good.
The platform is co-built with Anthropic's Claude. That is not a marketing line: a substantial share of the code, the tests and the content is written in direct collaboration with the model. Saying that openly feels more honest than hiding it, especially because Achtung.app itself measures AI models.
The person behind it
I've been building Achtung.app since early 2026 as a sole proprietor. Location: Berlin-Prenzlauer Berg; legal form: sole proprietorship (details in the imprint). My day-to-day work for years has been marketing and digitalisation projects; Achtung.app is the answer to a gap I kept running into there.

Common questions
Is Achtung.app the snake game on iPad?
No. The game "Achtung, die Kurve!" on iOS (at achtungapp.com) is a separate product, published in 2010 by an independent studio, and has nothing to do with this platform. This site is achtung.app (not .com) and measures brand presence in ChatGPT, Gemini and Perplexity.
Where is the data hosted?
In Germany and the EU. The application server, database and all stored brand data live with a German host running on green electricity. The AI queries themselves go to the respective providers (OpenAI, Google, Perplexity, Anthropic), where their terms apply — these are linked in the privacy policy.
Does Achtung.app only measure my brand if I am a customer?
Continuous measurement with daily runs, competitor tracking and reports is subscription-only. Anyone can run a free one-off check at /en/ai-visibility-check: five queries across two AI providers, results delivered by email.
What does Achtung.app cost?
The Starter tier is €89 per month and covers one brand, three search-grounded AI providers and 20 keywords. Pro and Enterprise scale brands, keywords, API access and the brand portal. Details on the comparison page.
