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. The problem has never been finding information. It's bringing it all together — and making it work for you, specifically. That's what Lykke does. 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. Personal to you. Capture from anywhere, in any form Use the share sheet to send anything to Lykke in one tap — links, screenshots, PDFs, images. Snap a whiteboard photo, use the stylus for handwritten notes, drop a voice memo, or paste a URL. Every format. Every moment. Every source. Auto-organize, so you never have to Lykke titles, and files every capture automatically — linked to the right course, ready to find. No folders. No manual sorting. Just a knowledge base that stays tidy with minimal effort from you. Chat with everything you've captured Once your bits of learning are in one place, Lykke brings them to life. Ask questions, get summaries, connect concepts across subjects. Your notes stop being static — they start answering back, shaped by exactly what you know and where you need to grow. Learn out loud, your way Tap to speak. Lykke's voice mode turns your knowledge base into a conversation built around you. Ask anything, hear an answer shaped by your own captured content. Perfect for commutes, walks, or any moment away from a screen. Never miss a deadline Lykke surfaces your assignments, due dates, and course commitments automatically — so your week is figured out before it starts. Offline, always No signal? No problem.
