Learn anything in five minutes a day.
Pip the otter turns a language, math or any topic you pick into short, game-like lessons that fit your level.
bite-sized
Lessons written for your level
Tell Pip what you know and how much time you have. Each lesson is a handful of quick exercises: pick the meaning, build the sentence, match the pairs, type the answer.
Get one wrong and it comes back at the end, with a short “why” whenever you ask.
stay motivated
Streaks, hearts and daily quests
A streak grows every day you learn. Hearts keep you careful, XP keeps score, and three small quests a day give you a reason to come back.
Pick a streak goal and Pip will cheer you all the way there.
any subject
Languages, math, or anything you type
Sixteen languages and math are one tap away. Or type a topic, like chess openings, music theory or Python, and Pip lays out a whole course of units for it.
Finish every unit and Pip writes the next ones.
