No textbooks, no guessing. Just data-driven practice.
Every drill is generated in real time based on your skill profile. Get it right and difficulty increases. Get it wrong and we zoom in on the gap.
We decompose each exam into atomic skill components and track them independently. No more guessing where to focus.
Ask anything about a question, grammar rule, or strategy. The AI tutor explains in as much detail as you need, so you actually understand — not just memorise.
Got 5 minutes? Do a speaking drill. Got an hour? Run a full simulation. Every session is timed, scored, and feeds back into your skill profile.
