Reanthesis Solves Your Huge Flashcard Backlog, and More
Type "anki backlog" and Google suggests "anki huge backlog" and "anki clear backlog." No moment ends more study streaks: two weeks off, a due count with four digits, and no plan. Reanthesis makes the comeback simple, and it does the same for three other problems where the usual answer is a tough workaround: uploading a deck with thousands of new cards, cramming the night before the exam, and connecting your AI to manage decks.
Clearing a huge backlog after a break
Vacation a week and a collection you kept up with has over 1,000 cards due. People describing this moment on study forums try options: grind it down, suspend everything, reset the deck, and, most often, quit.
Resetting is a non-starter. Delete years of history and every card starts over, including the hundreds you still know cold. Anki's own documentation gives the same advice after a long absence: keep the history, study as normal. But most quit.
Reanthesis doesn't want you to quit. It clears a backlog with a one-time spread. You say how many cards a day you can sustain, and every overdue card is assigned a specific day at that rate, counting the regular reviews that keep landing in the meantime. You see the date you will be caught up before you commit. The comeback is ordered by memory strength: the first sessions hold the cards you most likely still know, and the weakest cards arrive once you are moving again, on days of their own. That means you can clear lots of the easy cards right away as you get back into it. The spread is a single action, built to keep you studying.
Installing a massive premade deck
Premade decks changed how the big exams are studied, and they created a second problem: thousands of new cards on day one. A steady 20 new cards a day settles near 200 reviews a day. At 20 a day, a 4,800-card deck takes eight months to even see, and installing one mid-course means choosing between an unaffordable new-card rate and suspending most of the deck by hand.
Reanthesis MCAT is 4,800+ cards across all six subjects, with sources named on every card, and installing it changes nothing about your day: every card arrives dormant. Dormant cards hold their place and their progress, produce no reviews, and consume no new-card allowance. You wake cards when your course reaches them, three ways. Pick tags in Quick Wake Tags, and the matching cards become active. Or type one sentence about what you covered today, and Quick Wake Describe lists the matching dormant cards for you to confirm. Finally, the AI connectors let your Claude or ChatGPT wake and rest cards for you. Rest is quick too, including rest from the review screen by tapping the '...' on a card and picking to rest it.
Cramming before an exam
The night before a test, spaced repetition gives an unhelpful answer: most of the deck is not due. Alternative tools hide the workaround deep in their settings.
Reanthesis builds full-deck review in, called practice. Practice writes nothing; tomorrow's plan is exactly what it was this morning. You can cram for the exam and keep the long schedule intact, because the two never share state. Practice even lets you choose to review all, active, or studied, since sometimes rested cards will appear on the exam.
Turning lecture notes into flashcards with your own AI
Making cards is its own study session. An hour of lecture yields dozens of facts, and typing, formatting, and tagging them takes most of an evening. Reanthesis does make that easy to do by hand. You can try image occlusion right now, no account needed. But AI makes it faster still. A whole product category now exists for this: AI flashcard generators that take pasted notes and return a deck as a CSV for you to import, into a tool your schedule does not live in.
Reanthesis ships official plugins for ChatGPT and Claude instead. You open the AI you already subscribe to, upload the lecture PDF or paste your notes, and talk through the material in the same conversation. When you ask for cards, they are created directly in Reanthesis: basic and cloze, tagged, filed into your decks, a hundred of them if the lecture deserves it. What the connection can and cannot reach is written plainly on our trust page.
The review is best in Reanthesis - Tap, Flick, Bloom
Easy to read cards, tap to reveal, then swipe-to-grade, with the next card already loaded. Every card carries a plant that tells the truth about the memory underneath. Sessions open in seconds from any device; do a 2 minute speed round (just click the speed round button) between clinicals.
If your collection is in Anki today, it moves in one click: decks, media, and every review you have ever logged, with scheduling continuing on FSRS without a seam. If you are comparing tools first, start with our ranking of the alternatives.
Common questions
Should I reset my deck after a break?
No. Resetting deletes the review history behind every card, including the many you still know, and restarts them all from zero. Keep the history and spread the backlog across days you can sustain. Anki's documentation gives the same advice: study as normal after a break.
How do I clear a huge Anki backlog?
Raise the daily limit enough to see the real number, pick a daily amount you can sustain, and work the backlog at that rate starting with the cards you remember best. Or move the collection to Reanthesis in one click, history included, and spread it there the day it lands: every overdue card gets a specific day and you see the caught-up date up front.
Can my AI really make my flashcards?
Yes. Official Reanthesis plugins for ChatGPT and Claude work inside the AI subscription you already have: it drafts basic and cloze cards from your notes and PDFs, tags them, and files them into your decks, and you approve what it proposes.
