You can reread a chapter five times and still not be able to explain it. The words look familiar, so it feels like you know it. You don't, not yet. Usually you find that out at the worst moment, in an exam or when a coworker asks you to walk them through it. You learn. Pip runs the rest. Drop in lecture slides, a PDF, a work doc or a YouTube video. Tutor takes it one concept at a time and checks you've actually got it before moving on. Sometimes that's a quick question. Sometimes it asks you to explain the idea back in your own words, then shows you what you left out (harder than it sounds, honestly). And if an explanation doesn't land, ask for it another way. The stuff you struggled with doesn't vanish when the lesson ends. So Pip brings it back as quizzes and flashcards, and the day after you study there's a short Daily Practice pack waiting. Five minutes, maybe less. Working toward something with a date on it, like an exam or a certification? Pip plans back from it. Learning around a job works too, the sessions just get shorter. And if you're only curious about a topic, tell Pip and it'll find sources to start from. Also in the app: • A reader for PDFs, slides, articles and videos, where you can highlight a line and ask Pip about it • Study Notes from only the chapter you need • Listen mode, for when you'd rather hear it on the bus • Mind maps • Timetable import and scheduled study sessions • Group study sessions with friends, plus streaks, XP and leaderboards if a bit of competition helps • Assignment help that walks through a question step by step It's in 12 languages.
