結果元: Claude 3.5 Sonnet · テスト済み Feb 15, 2026Grok
Strongest at making language learning fun through immersive, conversational approaches that feel like talking to a witty native speaker. Great at teaching slang, colloquialisms, and real-world usage patterns. Less structured for systematic curriculum-based learning and formal grammar progression.
結果元: Grok 2 · テスト済み Feb 15, 2026Speak from day one, even badly. Waiting until you're 'ready' to speak is the biggest language learning mistake. Start having AI conversations immediately. You learn grammar by making errors and getting corrected, not by memorizing rules first.
Learn the 300 most common words first. The top 300 words in any language cover 65% of daily conversation. Ask AI for a frequency-ranked word list and master those before diving into specialized vocabulary. Coverage beats depth early on.
Use the language for something you already enjoy. If you like cooking, follow recipes in your target language. If you like gaming, switch the game language. Motivation dies when learning feels like homework. Attach the language to an activity you already love.
