AcquiLingua
Natural Conversation
Conversation first, everything else second
AcquiLingua's AI tutor holds real conversations with you in your target language, calibrated to your level and your interests. If you follow soccer, you talk about soccer. If you're preparing for a work trip, you practice that. The AI keeps the conversation in reach without dumbing it down, which is the exact condition your brain needs to start acquiring language rather than just memorizing it.
Powerful Vocabulary
Vocabulary that covers what matters most
Most apps teach vocabulary in random or arbitrary order. AcquiLingua follows Zipf's Law, which means you learn the most frequently used words in your target language first. About 1,000 words cover 80% of everyday conversation. Your Zipf Coverage Score in your dashboard shows where you stand in plain terms.
Listen. Understand. Speak.
Pronunciation you can actually measure
Voice recognition and IPA pronunciation training let you hear the gap between your output and a native model, and close it. Most apps either ignore pronunciation or reduce it to a green checkmark. AcquiLingua treats it as a core skill.
Privacy
Built differently from the start
AcquiLingua does not keep a permanent conversation-history feature. To make chat delivery reliable and prevent duplicate processing, we temporarily retain limited chat-response data and technical metadata. Completed chat-turn records are marked to expire after about 24 hours; deletion and backup retention are described in our Privacy Policy. Your data is not sold.
