I built my first flashcard generator as a study aid for a certification exam. The export was easy — a CSV with a front and a back column, rendered as HTML. The part that took me three rewrites was deciding what question to put on the front.

My first version just turned each bullet point into "What is X?" and the answer into the definition. It produced 60 cards in seconds and I learned almost nothing from them. The reason is obvious in hindsight: a question that hands you the concept in its own phrasing tests recognition, not recall. I was building a deck that felt productive and taught nothing.

The question is the product

Good flashcards come from the answer backward. Start with the fact you want to retrieve — say, "TCP closes with a four-way handshake" — then build a question that hides exactly the part worth recalling: "How many segments are exchanged to close a TCP connection, and what is the sequence?" That forces the learner to reconstruct, which is what sticks.

So I split my generator into two jobs. One job picks candidate facts from the source text. The other job rewrites each fact as a question that withholds the key term. The second job is where quality lives. A model is decent at it if you constrain the output to a single question and a single answer and forbid restating the answer in the question. FlashGen does this in one paste: you give it notes or a paragraph and it returns question/answer pairs you can copy straight into a deck, with a count you choose. I like that the count is explicit — 10 cards from a dense page beats 40 I'll never review.

Pick count matters more than people admit

I used to generate as many cards as possible, figuring more is safer. It isn't. A 40-card deck from one page means most cards test trivia, and the review burden kills the habit. Picking a smaller number forces the generator to surface the load-bearing facts instead of the footnotes. If you hand-roll this, set the count before you generate, not after.

No signup, copy-ready

The detail I cared about most as a solo learner: I didn't want an account, a sync service, or a locked format. I wanted text I could paste into Anki or just read. FlashGen returns copy-ready pairs, which fits the way I actually study — paste, skim, delete the weak ones, keep the rest.

The failure mode I keep seeing

The decks that fail aren't the ones with bad questions — they're the ones with too many fine questions. I've watched myself generate forty cards from a chapter, feel productive, then review three of them before quitting. The review habit dies under volume, and a dead deck is worse than none because it breeds guilt instead of study.

So now I cap generation hard and prune aggressively. If a card's answer is longer than two lines, it's testing reading comprehension, not recall, and I cut it. If two cards test the same fact from opposite sides, I keep one. The point of the generator is to hand me a draft I can argue with in two minutes, not a pile I'll feel bad about. Treat the output as candidates, not a curriculum, and the tool earns its place in the loop.

FAQ

Do generated flashcards replace writing my own?
They replace the tedious first draft. You should still delete the cards that don't test recall and rewrite any question that gives the answer away.

How many cards should I generate per page?
Fewer than you think. Five to ten from a dense notes page usually covers the load-bearing facts without burying you in trivia.

Will this work for non-technical subjects?
Yes. The question-from-answer logic applies to any factual material — vocabulary, history dates, formulas. The source just needs clear facts to pull from.

Is my notes text stored anywhere?
The tool is paste-first and copy-ready; nothing you paste needs to be saved to use it. Check the product's own privacy note if you want specifics.
