Vogi

Vogi is a German writing and speaking coach for adults who live in Germany and must learn German fast. It works like a teacher's red pen, not a ghostwriter. It marks where each mistake is and gives a hint, the learner fixes it, and only then does Vogi show the answer and the rule. Learners type a text or photograph their handwritten homework, and Vogi highlights each mistake on their own page. In Talk, they practise everyday scenes (the bakery, calling in sick, the Bürgeramt) hands-free, with a mission and feedback at the end, or describe their own situation and Vogi writes and draws the scene. In Learn something, Vogi builds a short lesson card by card and adds steps when the learner does not know. Vogi remembers each learner's mistakes in the browser and trains the ones that keep coming back; one file moves everything to another device. The learner picks one of four plain levels, and Vogi adjusts the level from their texts, A1 to C2. Live demo: https://avtak-vogi.hf.space (access code: koffer-apfel-1276).
