If you trust a tool with your investment decisions, even partly, you should know who runs it, how it works and where its limits are. This page answers exactly that – without the marketing fog.
What aktienanalyse.ai is
aktienanalyse.ai is a focused AI analysis tool, online since 2026, run by Daniel Herzog. Not a finance portal, not a news ticker, not a forum – but a single product meant to do one thing well: you enter a stock, and the AI condenses the company’s fundamentals into a structured analysis report. This focus is intentional. Instead of maintaining twenty half-finished features, we put all our energy into the quality of the analysis itself – and into the knowledge section, which gives you the tools you need to put the results into context.
How an analysis is created
The foundation is a database of around 1,900 stocks, each with about 40 fundamental metrics: valuation multiples, growth rates, margins, returns on capital, debt ratios and more. You can look up what each metric means at any time in the glossary.
On this basis, the AI creates the actual report. It doesn’t assess the metrics in isolation but in context – a high P/E ratio means something different for a fast-growing software company than for a utility. The result always has the same structure:
- Score (0–10): a condensed overall assessment of fundamental quality and valuation.
- Fair value range: a range of what the stock could be worth based on the data – deliberately not a precise figure.
- Verdict: the AI’s conclusion in one sentence, clearly labeled as an assessment.
- Bull and bear case: what speaks for the stock and what speaks against it – both sides, always.
- Scenarios: how the situation could develop if key assumptions hold – or don’t.
The Pro analysis also uses extended reasoning: the AI gets significantly more computing time to think through connections more deeply, detect contradictions in the data and work out the scenarios in more detail. The principle stays the same; the depth of analysis increases.
Our principles
An analysis tool depends on the trust of its users. That’s why five rules apply that are non-negotiable:
- No investment advice. Every report is a source of information, not a recommendation to buy or sell. You make the decision – with your knowledge of your goals, your investment horizon and your risk tolerance, which no AI has.
- No promises of returns. Nobody can predict share prices, not even an AI. Anyone who promises you otherwise is selling you something.
- Transparency about the limits of AI. AI analysis is strong at condensing many metrics, but it neither knows the future nor knows management personally. We’ve written in detail about exactly where its strengths and weaknesses lie in the guide AI stock analysis – including the uncomfortable parts.
- Ranges instead of false precision. A fair value of “exactly €187.43” suggests an accuracy that no valuation method can deliver. That’s why we always show a range.
- Clear separation of information and recommendation. Metrics and facts are recognizable as such, and so are the AI’s assessments. Nothing is mixed up, and nothing that is an interpretation is sold as objective truth.
What the analysis costs – and why
There are exactly two products: the Compact analysis for €2 and the Pro analysis for €10. You pay for each one individually – no subscription, no registration. What’s included in each version and how it’s calculated is explained in the methodology.
Why charge at all? Every analysis incurs real computing costs, and significantly higher ones for the Pro version with extended reasoning. The prices cover these costs and the operation of the platform – there’s no more business model behind it than that. The advantage for you: we don’t need to sell you anything else. No commissions from brokers, no paid stock recommendations, no interest in getting you to trade as often as possible.
