I built a simple email-based language learning bot that sends you daily messages in your learning language. You just reply like you're writing to a pen pal, and you'll get personalized responses and feedback based on your level the next day. This way you get consistent conversations practice through your inbox.
You can choose your level (Beginner to Advanced), pick the days you want to receive messages and add topics you're interested in. You can change your preferences via email later too. The bot currently supports Spanish, French and German, later we may expand.
