Aicademy

Aicademy turns a topic, your notes, or a PDF into a full study set: a lesson with clear explanations, then quizzes, spaced-repetition flashcards, notes and a learning path to go with it. Everything is saved in one place, so you can pick a subject back up days later, see your progress, and keep going. There's also a built-in tutor that answers questions about the exact lesson you're on.

The part that makes it different is that it adapts to how you learn. You choose the tone, how much detail you want, and what to optimise for (say, exam technique versus really understanding something), and the lessons, quizzes and explanations are generated to fit. Two people studying the same topic won't get the same lesson.

Alongside what you generate yourself, Aicademy has a large library of lessons written by people and mapped to real course specifications, so the content stays accurate rather than guessed. It works for almost any subject or level, from school and university to languages, computer science, or just teaching yourself something new.

The free plan covers 20 AI creations a month and 10 tutor messages a day. Pro (£4.99/month or £39.99/year) removes the limits.
