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.

Struggling to retain what you study? Most flashcard apps just let you type cards by hand and flip through them randomly. Revv-AI Flashcards takes a fundamentally different approach - it analyzes your study material, tracks how well your memory is holding up, and adapts every session to focus on the cards you are actually at risk of forgetting. Revv-AI is built for students, professionals, and lifelong learners who want every minute of study time to count. Import a PDF, let the AI generate a complete flashcard deck, then follow a session designed around your personal recall data. The app monitors your overall recall probability across each deck, grades your retention health from A+ to F, and shows you exactly how many cards you remember, which ones are slipping, and which ones are already forgotten - so you always know where to focus next. KEY FEATURES - AI Deck Generation - Import any PDF and the app extracts content page by page, then generates ready-to-study flashcard decks automatically. - Recall Probability Tracking - Each card is scored with a recall probability. The app separates your cards into Recallable, At Risk, and Forgotten groups so you can prioritize intelligently. - Health Grade System - Your deck receives a letter grade (A+ through F) based on your overall retention, giving you an instant snapshot of how well you know the material. - Adaptive Study Sessions - Sessions are structured around your current recall data, not a random shuffle. Cards you are losing track of come up more often. - Study Insights - After each session, review a personal insights summary covering session duration, cards reviewed, and progress trends over time. - Streak and Calendar Tracking - A built-in study streak and calendar view keep you consistent day after day. - Deck Categories - Organize decks by subject or category so your library stays easy to navigate as it grows. - Revv Pro Subscription - Unlock expanded limits and premium capabilities through an optional in-app subscription. - Sign in with Apple - Create your account securely with a single tap using Sign in with Apple. - Local Data Persistence - Your decks and study history are saved on-device so your progress is always available. HOW IT WORKS Start by importing a PDF of your study material - a textbook chapter, a set of lecture slides, or a reference document. Revv-AI processes each page, extracts the key content, and generates a flashcard deck for you. Once your deck is ready, you can review and organize it before your first study session. During a session, the app presents cards based on your recall data. As you progress through cards, your recall probabilities update in real time. When the session ends, head to the Insights screen for a full breakdown of your performance - how long you studied, your overall recall score, and which areas still need work. Over time, the home screen streak tracker and calendar show your study consistency, helping you build the kind of regular practice that leads to lasting retention. Whether you are preparing for a standardized test, a professional exam, or a university course, Revv-AI keeps your study plan grounded in data rather than guesswork. Your data stays on your device and is tied to your secure Apple account. No complicated setup, no manual card entry required to get started. Download Revv-AI Flashcards today and study with the clarity that only real recall data can give you.
