ANCHOKO — hide any diagram, then learn it Image occlusion on your phone, free. Drop boxes over the labels on an anatomy plate, a circuit drawing or a map, and each box becomes its own card. IMAGE OCCLUSION THAT ACTUALLY WORKS ON A PHONE • Draw rectangles, ellipses or free-form shapes over any picture • Each shape becomes a separate card, so one diagram teaches you twenty things • Pinch to zoom while you place shapes — small labels stay reachable • Show the other boxes while you answer, or hide them • Works on photos, screenshots, textbook scans and imported PDF pages BRING YOUR ANKI DECKS • Import .apkg files and keep your cards, your images and your deck names • Cloze deletions come across as cloze deletions • Image occlusion notes keep their boxes, on the right part of the picture • Note types ANCHOKO does not know are still imported, front and back — nothing is lost • You are told what changed during the import. No silent edits PHOTOGRAPH A PAGE, GET CARDS • Photograph notes, a textbook or a handout and the text is read on your device • Cards follow the page layout — "term: meaning", "word translation", numbered lists • You see the recognised text before any card is made, so misreads never become cards RED AND COLOURED TEXT, FOUND FOR YOU • Anything written in red pen or pink highlighter is detected and covered automatically • Switch to green, blue or yellow when that is what you used • Popular with students in Japan, who use a red filter sheet for exactly this REVIEW AT THE RIGHT MOMENT • The SM-2 algorithm works out, card by card, when you are about to forget • Four ratings — Again, Hard, Good, Easy — reshape the interval • See your forgetting curve and how much is left • Cap how many new cards appear each day HANDS-FREE BROWSING Cards flip themselves at timings you choose, with read-aloud for commutes. Auto-advance never grades your cards, so your review schedule stays intact. • Also: cloze deletions, and annotations written straight onto a picture YOUR PHOTOS STAY ON YOUR DEVICE Text recognition, red-text detection and PDF rendering all happen on your device. Photos and PDFs never reach an ANCHOKO server. MORE • XP, levels, 18 achievement badges, and a weekly ranking with friends • Publish your own decks, or download and try decks other people made PRICING Free, for as long as you like: • Up to 200 cards you make yourself — they stay yours even if you stop paying • Unlimited image occlusion boxes on the cards you make • The full spaced-repetition engine, and unlimited community decks • Photo-to-cards and red-text detection, 3 a day ANCHOKO Pro adds: • Unlimited cards • Unlimited photo-to-cards and red-text detection • PDF import • Auto-advance • Backup export • Your progress follows you across devices (below) Three plans: monthly, yearly, or a one-time Lifetime purchase. Amounts are shown on the purchase screen in the app. PICK UP WHERE YOU LEFT OFF, ON ANY DEVICE • iPhone, iPad, Android and the browser share the same cards, study record, streaks and XP once you sign in • Started without an account? Signing in later keeps everything you already made SAMPLE DECKS, ONLY IF YOU WANT THEM Nothing is added behind your back.
