Seuil

Daily, adaptive French practice for TEF/TCF: speaking, writing, reading, and listening with instant AI feedback. Build a streak and reach your target level.

Seuil ("threshold") is your daily companion for crossing into French fluency and passing the TEF and TCF exams.

Instead of generic drills, Seuil builds a short, adaptive session around your goal and your weak spots, then gives you instant, specific feedback, the way a tutor would.

WHAT YOU GET • Adaptive daily sessions: a focused mix of review, lessons, and practice sized to the minutes you have (5 to 60). • Four skills, exam-style: reading, listening, writing, and speaking, modeled on TEF/TCF tasks. • AI feedback that's actually useful: speak or write a response and get corrections, a CLB/CEFR estimate, and what to fix next. • A conversation tutor: practice real French dialogue at your level, hands-free. • Smart review: vocabulary comes back right before you'd forget it (spaced repetition). • Placement test: a quick adaptive check sets your starting level. • Progress that motivates: streaks, skill levels, and a clear path to your target.

WHO IT'S FOR Newcomers and applicants preparing for Canadian immigration French requirements, students, and anyone serious about reaching B1–C1 / CLB 5–9.
