The free and open source conversational language tutor for iOS.
Overview
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.
- Free and Open Source: No accounts required, no subscription.
- 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.
- Zero Telemetry: No analytics. No tracking. Your conversations stay on your device and 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.
OpenLanguage is built with Expo / React Native, using only native SwiftUI components via expo-ui.
