In order for me to really learn a foreign language, ChatGPT would need to message me (email, app, or WhatsApp) once or twice daily with questions that are appropriate for my language skill level. I could answer a question and then choose to engage in a further conversation - but always with the ability to ask what a particular word or phrase means in my native language. Over time, I would become better able to understand a wider range of vocabulary and tenses, etc. Has anyone ever seen such a solution or heard of anyone building such an app?
