Real use case

Claude Duet built a daily Mandarin practice

Brian wanted to relearn Mandarin and found the language apps he tried clunky or too generic. He gave Claude Duet some context about himself and asked it to study popular apps and build him a structured daily practice, which he says got him 80% of the way. Then he used Talk Mode: when he got lost on a phrase, he could say so midsentence and Claude helped him get back on track as he spoke.

Copy this prompt

I want to relearn [LANGUAGE]. My level: [WHAT I REMEMBER]. I have [MINUTES] a day and I mostly want to [TALK WITH FAMILY / TRAVEL / READ MENUS]. Make me a daily practice plan for 4 weeks with short vocabulary, one speaking drill and a 5 minute conversation each day. Then start today's conversation in voice. Speak slowly, and when I say I'm lost, give me the phrase in pieces and let me try again.
