Four steps, and the first three cost nothing. You go all the way to a complete path — the whole shape of the subject, every lesson in order — before anything is written or charged for.
Starting is one sentence. The questions take a minute. Then the part nobody else built: it keeps teaching you for four months.
A sentence, your slides, the handbook PDF, a YouTube lecture, a stack of links. Type it, paste it, or say it out loud.
I want to learn
Slides, PDFs, links, a voice note — or one plain sentence. Whatever you have.
Your level, your goal, your deadline, the hours you actually have. The questions a tutor asks in the first five minutes — one tap each.
How much do you already know?
What’s the goal?
Time each week?
The path draws itself, topic by topic. Lessons get written in the format their knowledge needs, land on your calendar, and come back for review before you forget.
Live, topic by topic — no spinner. Green means do it, amber means “this or that”, blue means anytime. Click any box and the lesson opens right there.

Un caffè e un cornetto, per favore
A coffee and a croissant, please
Nice — “cornetto” came out as “coretto”. Lean on the rn, then the double t.

29 voices, 20 languages. It hears what actually came out of your mouth, marks the word that slipped, and a role-play partner answers back in character.
Anyone can start a course. This is the machinery that gets you to the end of one.
No red badges, no pile of guilt. Mark a day done or skipped and everything after it re-flows to fit the hours you actually have.
Re-flowed. Nothing lost.
Finish a lesson and it quietly queues for review. Recall it easily, the gap widens. Fumble, it comes back sooner. Free forever, on every plan.
The Today screen: what's due, what slipped, what's next, where you left off — and whether your streak is alive. A morning digest lands daily.
Just try it and see if it fits you. Takes a minute. Costs nothing.
