Diät Planer
Every diet, fact-checked – a guide portal that writes, illustrates and narrates itself every day.
Overview
Diät Planer explains diets, meal plans and nutrition clearly and with sources – from quick weight-loss strategies to balanced eating and trend diets put to the test. The old site was rebuilt as a hand-coded Next.js portal: a new guide every day with infographics and a narrated video, plus a diet-type quiz that runs entirely in the browser.
Challenge
Health content has to be right. Publishing new articles, graphics and videos every day is impossible by hand – and a language model that invents numbers or studies is not a cosmetic flaw on a diet site but a risk to readers. On top of that, the site was meant to work without tracking.
Solution
A daily editorial pipeline: topics from real search queries, one model writes, a second one reviews as an independent referee against clinical guidelines and rejects when in doubt. Citations may only come from a vetted source list (DGE, WHO, AWMF, EFSA) or PubMed IDs checked against the NCBI database – anything that doesn’t match is dropped. Every article gets infographics with German labels, including an automatic distortion check, and an HD video with voice-over and subtitles, each with its own watch page for Google video search. Every AI-assisted piece carries the transparency notice required by Art. 50 of the EU AI Act; fonts and videos are served from our own server in Germany.
Result
A portal that grows every day: more than 130 pages in the sitemap and 35 narrated videos (as of September 2026), with cited sources and structured data for search engines and AI search – and not a single third party loaded until visitors consent.
