About AI Fin Hub
AI Fin Hub is a small, independent handbook for engineers who put large language models into markets. It has 45 tools that run in a browser tab, 224 articles with the maths shown, 30 glossary entries and a few dated benchmarks.
Tools link to the formulas they use. Articles link to primary sources where sources exist and say so where they don't. Corrections are dated and added to the page, never made silently.
What it publishes
- Tools45 tools
Calculators, comparisons, playgrounds and generators. Everything runs in your browser; nothing you enter is uploaded.
- Research224 articles
Guides, head-to-head comparisons, tutorials and method notes, published under the AI Fin Hub Research byline.
- BenchmarksBenchmarks
Dated reports with the method published, re-run when the data changes.
- Glossary30 terms
Risk, backtesting, market structure and AI-in-markets terms, each linked to the tools that compute it.
What it will not publish
Investment advice. Every tool and article is education under the BaFin and EU framework; nothing here recommends buying, selling or holding a security.
Calls on real tickers. Examples use placeholders such as SYNTHETIC_A; a real ticker appears only where it cannot be avoided, never with a direction.
Personalised output. A tool computes from the inputs you enter; nothing profiles you or recommends based on who you are.
It documents methods and evidence, not anyone's trading. Its models are publications that lead with data and method: Our World in Data, QuantPedia, the Stack Overflow developer survey, Databento's research blog.
How the site is built
It is a static site on Cloudflare Pages with no back end and no accounts. Tools that call a model use your own API key, which stays in the page and goes only to that provider. There are no cookies, fingerprinting or cross-site trackers; visits are counted in aggregate by Cloudflare's server-side analytics. Every tool and quantitative article links to a method page with its assumptions, sources, formulas and limits, and every tool has a machine-readable contract for software agents (see for agents).
Standards
The editorial standards cover sourcing, fact-checking and conflicts of interest. The sponsor disclosure states the funding: self-funded, with no sponsors, affiliate links or paid placements. The corrections log is public and only ever added to.
The series
AI Fin Hub is one volume of a series that shares its design and editorial standards: AI Fit Hub (calculators for lifters and runners), AI Biz Hub (numbers for solo AI founders) and AI Dev Hub (developer tools and APIs for AI). It is run from the EU; see the contact page and the impressum.
