Learning doesn't happen in one place. It happens in fragments — a link you stumble on, a voice memo between classes, a photo of a whiteboard, an article shared by a friend.

Capture any fragment of learning from anywhere on your phone. Lykke pulls it in, organizes it automatically, and connects it to your coursework — building a knowledge base that grows stronger the more you feed it. Once everything is in one place, your learning becomes truly personal: chat with your notes, ask questions out loud, and get answers shaped around what you already know. Bits in. Understanding out.
