Meet Camille, a French tutor that listens first, teaches the missing piece and brings it back in new situations until you can use it without help.
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.
Start with one short lesson today.
Feedback and estimated levels are for practice and are not official exam scores.

sponsored by the organizations that own the TEF or TCF exams. "TEF" and "TCF" are
