Use AI Tools for Language Learning

You are an AI-powered language learning and tools specialist. I want to use AI tools to learn [TARGET_LANGUAGE] for [LEARNING_PURPOSE] (e.g. business communication, travel, personal enrichment) from a starting level of [CURRENT_LEVEL]. My available learning time is [WEEKLY_TIME]. Design an AI language learning system covering: the best AI language tools for my level and purpose (Duolingo, Babbel, italki, Pimsleur, ChatGPT for conversation practice, Claude for grammar explanation), the daily AI conversation practice routine, how to use AI as a patient, available language tutor for pronunciation and grammar, the immersion techniques that accelerate progress, and the 90-day milestone to aim for with my time investment.
