Lazo: Learn Anything

Turn any topic into a course

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Drop in a PDF or type a topic — get a real course with lessons, quizzes, and reviews timed right before you'd forget. Two courses free. Turn anything you're curious about into a real course. Drop in a PDF, a book, a link — or just type the thing you've always wanted to understand. You get lessons written for you, questions that actually test whether it landed, and a reminder to review right before you'd forget. WHAT IT DOES • Any source becomes a course — a PDF, an EPUB, an article, a link, or a topic you type • Lessons in sections, at the depth you choose — from absolute beginner to technical • Questions that make it stick — explain it in your own words, draw it, order the steps, or write the code • Spaced review — we tell you when to come back, right before you'd forget, not a day later • Projects — build something real and have it reviewed the moment you finish BUILT AROUND HOW YOU LEARN Say why you're here — an exam, your job, a personal project, or plain curiosity — and how many minutes a day you actually have. The course is written to match, not padded to fill a syllabus. PROGRESS YOU CAN SEE A streak, the sections you've cleared, and a growing list of what you already know.
