Type in any subject. Arti builds your course, teaches one concept at a time, and asks you to explain it back before moving on.
You read a clear answer. It feels like learning. A week later it is gone, and you never found out what you missed.
Arti builds the curriculum, teaches one concept at a time, and will not move on until you can explain it back. You find out in ten minutes whether you actually understand it.
Type any subject, or upload a book, manual or PDF. You get a full personalized learning system, built live.
Short lessons, each followed by a real comprehension check. No scrolling past it, no skipping ahead.
Gaps get fixed on the spot. What you proved comes back on a review schedule, right before you would forget it.
Books, trade training, a skill you are teaching yourself, a policy manual. If you can name it or upload it, Arti can turn it into a course.
You do not advance on a nod. Each concept ends with a check, and you get two tries on it. After that, "Still stuck? Get unstuck →" asks a few short questions to find where it broke down.
Spaced repetition brings each idea back before it fades, so what you learn this month is still there next year.
In 1984, educational psychologist Benjamin Bloom published a finding that has shaped the field ever since: students taught one-to-one performed about two standard deviations better than students in a conventional classroom. The average tutored student scored above roughly 98% of the students in the control group. Kurt VanLehn's 2011 review in Educational Psychologist found human tutoring produced an effect size of about d = 0.79 against no-tutoring instruction, and intelligent tutoring systems about d = 0.76 — against the 2.0 and 1.0 that had been widely assumed for each: both real, substantial effects, neither one two sigma. MasteryLoopHQ is built to bring that kind of attention to anyone with a phone.
