MemoryForge turns any subject into lasting knowledge โ powered by proven spaced repetition science and AI that builds your cards for you. **Build cards faster. Remember longer.** Create memory cards from a topic with AI, then review and save them when they are ready. Turn notes, worksheets, and study material into memory cards with Photo to Card. Review on the train, at home, or anywhere โ your core decks and reviews stay available offline. Use Child Mode from the Parent Dashboard to suppress ads, tracking, and purchase screens while checking recent on-device study activity. **Study Smarter with SM-2 Spaced Repetition** MemoryForge uses the battle-tested SM-2 algorithm to schedule exactly which cards you need to review each day. Rate each card Again, Hard, Good, or Easy โ the algorithm adapts in real time. Cards you know well disappear for days or weeks; cards you struggle with return sooner. You learn faster and forget less. **AI Card Generation** Type a topic โ "Organic Chemistry", "JLPT N3 Vocabulary", "AWS Certifications" โ set a quantity, and let MemoryForge generate a full deck in seconds. Powered by GPT-4o or DeepSeek, the AI produces front/back pairs with optional study notes, ready to review immediately. **Offline-First. Always Ready.** Every core feature works without a network connection. Your decks, reviews, and statistics are stored locally on your device. Open the app and start reviewing โ no login required. **Two Review Modes** Reveal Mode: Tap to slide the answer into view for a clean, distraction-free experience. Flip Mode: Classic 3D card-flip animation for the tactile learners. **Text-to-Speech (TTS)** Tap the speaker icon to hear any card read aloud. Perfect for language learning โ train your ear while you train your memory. **Streak & Statistics** Stay motivated with a daily study streak. Track progress through weekly activity charts, grade distribution, total reviews, accuracy rate, and longest streak. **Card Library & Flexible Import** Browse curated card packs or import your own cards via JSON. Duplicate detection keeps your decks clean. **Privacy First** No account required. Your data stays on your device. API keys are stored in the iOS Keychain โ never on a remote server. --- MemoryForge is free to use โ no account required.

Kakushi

Kakushi turns any photo into a reusable study sheet. Paper red sheets only work on specially printed text. Highlighter pens are permanent and ruin your notes. Kakushi solves both: photograph any page, notebook, or textbook, brush thick black marks over the words you want to memorize, and tap each mark to reveal the answer. Tap again to hide it and test yourself once more โ as many times as you like. No typing. No setup. Just snap, brush, and tap. WHY KAKUSHI - Works on anything: your own notes, printed handouts, photos, textbooks - Precise tap to reveal: open one answer at a time, not the whole page - Freehand strokes, rectangles, and lines to cover exactly what you need - Reveal all or hide all in a single tap for a full run-through - Organize sheets into folders like "English Quiz" or "History Dates" - Gentle review reminders so you look again before you forget HOW IT WORKS 1. Take a photo or pick one from your library 2. Brush black marks over what you want to memorize 3. Open Study mode and tap each mark to check your answer KAKUSHI PRO Create unlimited study sheets with no ads, as a monthly plan or a one-time lifetime purchase. Free members can create up to five new sheets each month; editing and reviewing are always unlimited.
