AI Tutors Flashcards: Turn Any Topic Into Study Cards in Seconds

Most "make me flashcards" prompts produce something usable on the first try and something quietly wrong on the fifth — a hint that gives away the answer, a card cramming two facts into one front, a run of twenty cards nobody asked to review in one sitting. The flashcards skill from aitutors.me's public plugin repo exists because a card-generation prompt without guardrails degrades exactly that way, and the fix isn't a better prompt — it's a format spec an agent actually has to follow.

What it does

The skill turns source material — notes, a textbook page, a topic — into flashcards in aitutors.me's own JSON format, validated against the same QA rules the platform's in-app card composer enforces on every card a human or a tutor creates. It doesn't call an API, doesn't hold account state, and carries no curriculum content of its own. The output is plain JSON a person pastes into an import page, where it lands as a private draft deck. It's a format-and-quality-control layer, not a tutoring engine.

The rules that actually matter

Two constraints in the skill's design do most of the real work, and they're the kind of thing that's obvious once stated and easy to violate by default:

One fact per card. If a front needs "and" to describe the answer completely, it's two cards, not one. The instinct when generating cards quickly is to pack related facts together for efficiency — the skill's whole point is that efficiency at generation time creates a worse study artifact, because a card testing two things at once tests neither cleanly.

A hint can never contain a word that also appears in the answer. This sounds like a small rule and turns out to catch a genuinely common failure mode — writing a hint that half-gives-away the answer by echoing its own vocabulary back. A hint has to narrow the search without leaking the destination, which is a harder and more useful discipline than it first sounds.

On top of those two, the skill distinguishes six card kinds — basic, basic-reversed, type-in, cloze, cloze-multi, and image-occlusion — and picks the right shape for the material rather than defaulting to one format for everything. A name-and-definition pair becomes a reversible pair automatically; a sentence with several blanks fans out into one card per blank without the person asking having to split it themselves. There's also a hard ceiling of eight cards per import batch, matching the platform's own limit, so the skill offers to split a large set across multiple pastes rather than silently producing a batch that gets truncated past the eighth card.

Why the constraints are the feature

The value of this skill isn't "it makes flashcards" — plenty of things make flashcards. The value is that it encodes, in an enforceable way, the difference between a card that survives contact with a real study session and one that only looks fine in the moment it's generated. A hint-leak or a multi-fact front doesn't fail loudly; it just quietly makes the deck less useful every time the learner reviews it, and that kind of failure is exactly the sort a general-purpose "write me flashcards" prompt won't catch on its own.

It ships under the MIT licence, which matters practically: the format spec itself is free to read, adapt, or point any other flashcard tool at, unlike some of the other IP in the same repo. If you're building anything adjacent — a study app, a different tutoring product, your own spaced-repetition tool — the card-kind taxonomy and the hint-leak rule are worth studying even outside the aitutors.me ecosystem.

Who it's actually for

A parent turning a KS3 revision topic into cards for their child, a student converting their own lecture notes, or a builder who wants a reference for what a rigorous flashcard-authoring skill looks like before writing their own. It's deliberately narrow — no tutoring, no hint ladder, no account logic — which is exactly what makes it easy to trust for the one job it does.
