Trust, but check
How to Check AI-Generated Anki Cards Before You Study Them
AI cards fail by omission more often than by invention. A ten-minute audit against your objectives and slides, and what to do with each thing you find.
"AI may leave holes in the content and not create flashcards you know you would need." That was the opening argument of an r/Anki thread titled, roughly, you should not use AI to make cards at all. The reply that drew the most agreement did not argue back. It said: fine, but "definitely don't do it without checking the output."
This page is the check. It exists because a generated deck can miss a detail or put the weight on the wrong slide, and because reading every card slowly is not a check, it is a second card-making session. Ten minutes with the objectives open and the slides beside you catches most of what matters, and the rest turns up during review.
Two failure modes that matter, and the one everyone fears
The fear is hallucination: a card that states a wrong dose or invents a mechanism the lecture never mentioned. It happens and you should look for it. But when the source is your own lecture and the generator is bound to it, invention is the rarer failure. Two others are more common and much harder to see.
- Silent omission. The professor spent four slides on the differential and the deck has one card on it. Nothing on any card is wrong. A card that should exist does not. You cannot find a missing card by reading the cards you have.
- Confident wrong emphasis. Five cards on the history-of-the-discovery slide, one on the mechanism the exam will ask three questions about. Every card is accurate on its own. The deck as a whole points you at the wrong material.
The ten-minute audit
Set a timer. Open three things side by side: the lecture's learning objectives, the slides, and the deck, either in Anki's card browser after import or in the library before it.
- 1
Objectives first (three minutes)
For each learning objective, find at least one card that tests it. Objective four has no card? Write it down. That is a hole, and you will fill it by hand in a moment.
- 2
Sample five cards against their slides (three minutes)
Pick five at random, not the first five. Find each card's slide. Does the card say what the slide says? Is there something on that slide the card should have carried and dropped?
- 3
Check the high-stakes numbers (two minutes)
Search the deck for every dose, lab value, cut-off, stage and grade. Check each against the slide. Numbers are where a wrong card does real damage, and they are also the fastest thing to verify.
- 4
Look for two cards testing one idea (one minute)
Skim the fronts. Two prompts approaching the same relationship from two angles are one card and a duplicate. Keep the one an exam question would ask.
- 5
Look for prompts that can mean two things (one minute)
"What is the treatment?" with no context has three correct answers. Add the context to the prompt or delete the card. A prompt you can answer two ways will teach you to argue with yourself during review.
What to do with what you find
Each finding has one action. Do the action and move to the next card. The audit fails when a wrong card turns into a twenty-minute rewrite of the whole subdeck.
- Wrong fact: edit the card to match the slide. If the slide does not support the claim at all, delete the card.
- Missing objective: write one card by hand. This is the one place manual card-making earns its time, because you have just located the exact hole.
- Wrong emphasis: suspend the cards on the footnote slide and add one or two on the heavy topic. Suspend rather than delete, in case the footnote turns out to be the professor's favourite.
- Duplicate: keep one. Ambiguous prompt: add the context or delete.
Edit during review, not before it
When the timer goes, stop auditing and start reviewing. The urge to polish every card before the first review is how the lost evening comes back through a different door. Making cards takes too long covers that trap in full. The short version is that review is a better auditor than reading.
A card you fail three times is either important and badly written or simply wrong, and either way you have found it. A card that reads fine but that no exam would ever phrase that way reveals itself the first time you try to answer it. Edit at the moment of failure, when the slide is one flip away and the context is in your head. Then move on. One learner on r/Anki described exactly this loop with their own generated cards: "instantly fix a potential error, decide not to add a card, or change the order." The fix happens in flow. It does not happen in a separate session before the deck is allowed to exist.
What the source slide on the back is for
Every card SynapticRecall generates carries the image of the slide it came from on its back, along with a short note on why the point matters. Step two of the audit becomes one flip: read the card, turn it over, see the slide. Practice questions do the same, with the source slide beside each explanation. On the Standard plan and above you can edit cards in the library and re-download the deck, so a fix lives in the source, not only in your local copy. The generator is instructed to prioritise learning objectives, repeated emphasis and in-lecture questions, and to stay under roughly three cards per content slide, which limits the damage a wrong emphasis can do but does not remove it. See PDF to Anki for the full flow and how many cards a lecture should produce for the cutting that follows.
To say it plainly: the tool can miss a detail. It can misread which slide was the important one. It is bound to your lecture, which makes invention rarer, and it still needs the objectives-first check above every time. These are study aids. They are not written, reviewed or supplied by NBME, NBOME or any examination board, they do not replace UWorld or your faculty's question bank, and they are not for patient-care decisions. Verify every dose, lab value, staging criterion and treatment against the lecture and current guidance. Our position on this is on the accuracy and responsible use page. This page exists because the check is necessary, not because it is optional.
Questions students ask
Quick answers
Can I trust AI-generated Anki cards?
Trust them after you check them, not before. A generator bound to your lecture rarely invents facts, but it can leave out an objective or weight the wrong slide. Ten minutes with the objectives and a five-card sample against the slides is enough to know whether a deck is usable.
What is the most common mistake in AI flashcards?
A missing card, not a wrong one. The deck skips an objective or under-covers the topic the professor spent longest on. You catch it by checking the objectives against the deck, because you cannot see an absence by reading the cards you have.
Do I need to check every card?
No. Check that every objective has a card, sample five cards against their slides, and verify every number. Then start reviewing. Failed cards will show you the rest.
What if a generated card has a wrong dose?
Edit it against the slide, then check the other numbers in the deck, because one wrong figure means the sample should be wider. Treat every number as unverified until you have seen it on the slide, and never use a generated card as a source for patient care.
Should I still make some cards by hand?
Yes, for the objectives the deck missed. Hand-making a card is worth the time when you already know exactly what is missing. It is not worth it as a substitute for the audit.

Check it in one flip
Generate a deck with the slide on the back of every card
Upload one lecture. Every card and every practice explanation shows the slide it came from, so the ten-minute audit is a flip, not a search.
