Two worlds — data & engineering on one side, language & the rest on the other. Each course a self-contained workbook with reading, listening, writing, speaking, and a personal final test.
Notebooks, pipelines, warehouses, dashboards, and data models — from the first job to a production system. Five courses for anyone who touches data every day.
Three tracks — Alltag for everyday life, Beruf for the workplace, IT for software and data teams — from A1 to C1. Interactive chapters with click-through Wortschatz, hover-to-understand Grammatik, flashcards, and AI-graded speaking + writing. Read everything in your language.
Config-driven interactive school lessons — read in German or English, with section-by-section checks that open the next part only once you've understood this one, and every answer explained step by step. Grade-4 maths for Hessen, and a compound-interest primer.
