Every mistake gets caught, logged, and checked.
Homework and lessons run through a system built for exactly one thing: the specific ways your first language smuggles itself into English. Today that means French, German, Italian, Polish, Portuguese and Spanish. Every pattern is checked against your real history: collocations translated word for word, prepositions borrowed from the wrong language, false friends that sound right and mean something else. Nothing is guessed. In lessons, every correction comes from your teacher. On campaigns, Clara, Nuance's AI marker, marks the daily work, and your teacher validates the certificate.
Real people. Real progress.
Every resolved pattern becomes part of a handbook that's yours to keep: searchable, permanent, recoverable at any depth.
"Henri will show you that you're better than you think, and his approach is genuinely motivating without ever being pushy."
WiktoriaStudent since 2025"Structured, well-prepared lessons shaped around my actual work: he built role-plays around a real audit I was preparing for. You can tell he genuinely cares about your goals."
CyndieStudent since 2026"He never puts pressure on you. The environment is calm and safe, and it's clear he's experienced enough to make every discussion genuinely interesting."

AI now scores your first interview.
Async video interviews scored by AI are the default first round at most large employers. INT30 gets you ready for both rounds: the AI-scored one and the human panel that follows.
- Apps are good at vocabulary and at feeling productive. They don't teach you to use the language, hold you to anything, or show you whether you're improving. I'm the other end of that spectrum: a real human, real feedback, real evidence.
- On a marketplace, every lesson starts from zero. Nobody keeps a record of what you got wrong last month. Here, every mistake goes into a model of your English that gets sharper with time. You're not paying for an hour; you're paying for the hour and everything I remember from the ones before it.
- Some of the catching is. Lessons and homework are transcribed and checked against a library of interference patterns for speakers of French, German, Italian, Polish, Portuguese and Spanish, which a machine is good at. The explaining, the correcting, and the decision that a pattern is truly resolved are mine. Machines detect better than they teach, so that's how the work is split.
- Lessons: the lesson plus roughly an hour of homework. Campaigns: fifteen minutes a day. If you can't find that, tell me and we'll pick the lighter option rather than the one you'll abandon.
- Twenty minutes. We talk in English, I listen for how your first language is showing up in your English, and I tell you honestly which product fits, or that none does yet. You leave with a plan either way.
- Anything from A2 upward for lessons. Campaigns work best from B1, because they assume you can already produce sentences and we're refining them.
- Yes. A campaign alongside weekly lessons is common.
- Lesson packs don't expire. Your record stays yours. If you come back in a year, we pick up where the evidence left off.
- Not yet. Qualiopi certification is under way; I'll say so on this page the day it's live.
- Your lessons, homework, and progress live on my own server. Not sold, not used to train AI models, deleted on request.
Fluency in thirty days. Progress without homework. That a pattern is fixed because you got it right once. It counts when you get it right weeks later, unprompted. And no CPF funding, for now.
