ABOUT ORATIUS

For people who study
how languages work.

Oratius is built for people who have learned languages before and want to understand the next one in depth. You can begin a new language here without beginning again as a learner.

Our approach

Work through structured lessons, formulate your own answers, and examine the choices behind them. The AI tutor gives one useful hint at a time, explains directly when needed, and asks you to apply what you understand.

Precision in service of expression

Grammar provides a vocabulary for understanding language. We use technical terms where they clarify a distinction, alongside examples and reference material. The aim is independent expression, not simply naming rules.

Oratius uses OpenAI to teach. When you ask for feedback, hints or placement, we send your answer, relevant conversation and learning history, and the exercise to OpenAI. If you choose to record speech, we send that recording to OpenAI for transcription. Oratius does not save the recording; submitted text and feedback are saved with your progress. Avoid sharing sensitive personal information. AI can make mistakes. You can withdraw permission in Privacy settings; browsing your lessons remains available.
