OpenLanguage

OpenLanguage pairs a capable AI tutor with voice I/O so you can practice speaking and listening the way you actually learn a language — by using it.

The tutor adapts to your level, corrects you naturally mid-conversation, and never gets tired of your questions. Pre-made conversation topics for every level make jumping in a breeze.

• Fully Open Source.
• No accounts required.
• Bring Your Own Keys: Plug in your own API key from OpenAI, Anthropic, or any compatible provider. You pick the model and pay only for what you use. Your conversations stay between you and whichever API provider you configure.
• Voice I/O: Uses iOS's built in voice recognition and speech to text for free, on-device voice I/O.
