Koko: Language Practice

Koko gives you unlimited conversation practice while keeping your voice, information, and data private on your device. Nothing leaves your iPhone. It can even be run in Airplane mode :)

Learn a new language by speaking and listening more! A lot of people struggle to actually hold a conversation when learning a language because they don't practice speaking and immersing themselves in the language.

Features We Love:

• Fully private. Your voice and conversations never leave your device.
• Conversations are scaled to your level. For beginners, Koko uses small, beginner-friendly words and speaks slowly. For advanced speakers, Koko speaks quickly and uses advanced vocabulary.
• Quick translations
• Feedback on your responses to help you learn how to speak better
• Cloud mode: Get started quickly by using our private cloud LLM instead of downloading the models locally

Current languages:

• English
• Spanish
• French
• Italian
• German
• Japanese
• Polish
• Vietnamese

Koko requires iOS26+ in order to run the conversation models on your own device.
