Anaptu

Write one sentence about what you want to learn - pass an exam, ship a REST API, understand how vaccines work. In under a minute Anaptu builds a focused plan of topics (it calls this a compass), then teaches each one through a back-and-forth lesson with quizzes, flashcards and exercises, and keeps track of what you've finished. You can open a side thread to ask a question without losing your place, or build a plan from your own lecture PDFs. It works in English and Hebrew, including a right-to-left interface. Free to start, no card needed. Pro is $9 a month and raises the daily limits (messages go from 200 to 2,000 a day, learning plans from 5 to 100). Still in beta. Built by Nadav Oxenberg.
