Frequently asked questions

Seuil (French for “threshold”) is a mobile app for preparing to pass the TEF and TCF French exams. It builds a short, adaptive daily session around your goal and weak spots, covering reading, listening, writing, and speaking, with instant AI feedback on what to fix.

Seuil is modeled on TEF and TCF tasks and reports estimated CLB and CEFR levels, targeting B1–C1 / CLB 5–9. It’s designed for people preparing for Canadian immigration French requirements as well as students and anyone serious about reaching fluency.

No. You can tap “Get started” and use the full app as a guest. Creating an account is optional and only needed to sync your progress across devices.

When you speak or write a response, Seuil sends it for AI analysis and returns sentence-level corrections, an estimated CLB/CEFR level, and a clear “fix this next.” Feedback and levels are for practice and are not official exam scores.

Speaking practice and the conversation tutor use your microphone to record and score your French. Recordings are sent securely for feedback and are not shared. You can use all other features without it.

You can start practicing for free. Tap “Get started” and begin with one short lesson today.
