Lectra is a professional workspace for the documents you think on. RECORD THE LECTURE, NOT JUST THE NOTES Start recording from a control that floats above the whole app, then keep writing. Tap a handwritten stroke to hear what was being said as the pen moved. Drag the playhead and watch the page fill back in, stroke by stroke. Transcription runs on device, and an hour of lecture compacts to about 15 MB. BUILT FOR STUDENTS AND ANYONE WHO READS CLOSELY Lecture slides, problem sets, papers, and textbooks. Annotate your readings, write notes beside them by hand, scan whatever you got on paper, and keep the whole semester in one library that works without a signal. READ AND MARK UP Open any PDF and work it over with Apple Pencil, pressure-responsive pen, highlighter, and eraser in a dark, distraction-free editor that keeps your ink sharp at any zoom. Select the document's own text with a finger. Apple Pencil Pro squeeze switches tools. ASK YOUR DOCUMENTS Ask a question about what you're reading and get an answer that cites the page it came from, computed by Apple's on-device model. Summarize documents and get to the point faster. Your documents are processed privately, on your iPad. NOTEBOOKS AND WHITEBOARDS Start from blank paper when the thinking hasn't found a document yet. Notebooks, paper styles, and room to sketch, then export your pages as PDFs. SCAN ANYTHING Bring paper into the record. Scan documents with the camera and mark them up like any other PDF. WHEN READING TURNS INTO WORK Run Python where you're already working, notebooks with charts, a real shell, Git, and a code editor, all on the iPad and all offline. The document and the work on it stay in the same place. A LIBRARY THAT KEEPS UP Everything in one place, available offline, and backed up when you sign in. Your documents are yours: export them anytime, in formats that open anywhere. YOUR MAC, TOO Lectra for Mac is a free download at canvascope.org/mac, the whole app on your desktop, plus your Mac on your iPad as a remote desktop, documents sent straight from iPad to Mac, and a shared clipboard. Now in Spanish and French. Lectra is free to use.

Add the word you just saw. Then actually remember it. And if you want, challenge a friend to a duel. Membra doesn’t force you to study from a ready-made word list. Add the words you hear in a show, see in an article, or write down in class. Membra brings them back when you’re starting to forget them. NO LIMITS ON LEARNING No energy. No lives. No daily lesson limits. Add as many words as you want, review as much as you want, and play as many duels as you want. YOUR PERSONAL DICTIONARY Type in a word and Membra detects the language, translates it, and places it on the correct side. Each language pair has its own dictionary. Your English dictionary stays separate from your German one, and you can switch between them in a single gesture. REVIEW BEFORE YOU FORGET Membra uses spaced repetition to bring words back when you’re starting to forget them. It doesn’t just ask whether you “knew” the answer. How quickly you respond, whether you use a hint, and the mistakes you make all affect when that word comes back. There are four review modes: flashcards, multiple choice, typing, and mixed. If you have nothing due that day, you can keep going with free practice. REAL-TIME WORD DUELS Compete against another player in live 1v1 vocabulary battles. When you attack, you choose the word your opponent has to answer. But don’t make it too easy — a fast answer can turn the advantage back against you. The match continues until a tower falls. Can’t find an opponent? 11 different training opponents are waiting for you, each with their own personality, speed, and way of talking trash. See a useful word during a match? Add it to your dictionary with one tap when the match ends. EXAM PREP Get a 600-word pack for YDS and YÖKDİL, IELTS Academic vocabulary, and English word packs from A1 to C2. They’re all free and can be added to your dictionary with one tap. BUILD THE HABIT Daily streaks, streak freezes, daily and weekly missions, ranks, monthly leagues, and leaderboards. Add friends, nudge them, send words, and compete for a higher spot. LANGUAGES Membra is available in English, Turkish, German, French, and Spanish. You can also create your own personal dictionaries between these languages. ONE HONEST NOTE Membra is not a language course. Instead of taking you through a fixed curriculum from A1 onward, it’s designed to help you collect the words you come across in real life and actually remember them. If you want to learn your own words and stop forgetting them, you’re in the right place. We don’t sell your data. We don’t use ad networks. You can permanently delete your account whenever you want.
