The ranking
Duolingo — best for daily practice
Duolingo's genius is psychology: bite-sized, gamified lessons that turn 15 minutes a day into a habit you actually keep. The AI personalizes your path, and Duolingo Max adds Roleplay (AI conversations) and Explain My Answer (Claude-powered grammar help). For building vocab and grammar consistently, nothing beats it.

Claude — best for grammar & writing
