Type a skill — in a minute you get a course that teaches, checks you, finds your weak spots and won't let you forget.
You are reading these lines — and right now they feel obvious. But memory is honest: a week from now, without review, only this remains.
That was the forgetting curve — from the inside. Alerne reviews with you before knowledge disappears.
Any chat can generate text. Alerne builds a closed learning loop — a system that takes you from “read it” to “still remember it a month later.”
AI assembles a program of modules and lessons — with goals, examples and logic built for your request, not a template from a catalog. The first lessons are ready in a minute.
A 7-question quiz adapts to your answers: doing well — questions go deeper, struggling — back to the foundations. Questions test understanding, not memorized wording.
Alerne analyzes not what you answered but why. It finds the systematic misconception — and turns it into a personal drill before it settles in.
You're confusing ser and estar: permanent traits vs. temporary states.
Without review, most of what you learn fades within days. The FSRS algorithm computes the moment a topic starts slipping and brings it back as a card — minutes a day.
Forgetting curve, schematic. Markers — reviews scheduled by FSRS.
The knowledge map shows mastery of every concept and a forgetting forecast. Not “finished the course” but “own the topic” — and you see exactly what to shore up.
A real Alerne-style question. Answer it — and watch what the engine does with your answer.
Flashcard apps do intervals — but you write the course, the questions and the deck yourself. Alerne does it for you.
Ebbinghaus, 1885: memory fades along a predictable curve. Which means the moment to review can be computed.
An open next-generation spaced-repetition algorithm — schedules every card for your memory.
Question difficulty follows your answers — like serious examination systems.
A wrong answer is a symptom. The engine finds the cause and treats it with a targeted drill.
Stuck? Ask right inside the lesson: it explains differently, gives an example.
A separate practice mode: questions hit exactly your gaps and misconceptions.
Learn a little every day — the system keeps your rhythm and reminds you in time.
