About this tool
Build an AI prompt that produces clean, importable question-and-answer flashcard sets in basic, cloze or term-definition format.
The Flashcard Prompt Builder creates an AI prompt that outputs a clean, importable flashcard deck — one fact per card, in basic Q&A, term-definition or Anki cloze format. The card rules follow the minimum information principle from SuperMemo's Twenty Rules of Formulating Knowledge, and output is tab-separated front/back lines that import directly into Anki. Decks over 40 cards are automatically split into batches so no response gets truncated.

The prompt enforces the minimum information principle — no compound questions, no yes/no cards, no duplicates.
Tab-separated front/back lines with no numbering or commentary paste directly into Anki's text import.
Requests over 40 cards are split into near-equal batches, keeping every response complete and on-format.
It is the rule that each flashcard should test exactly one small fact with the shortest possible answer, formulated in SuperMemo's Twenty Rules of Formulating Knowledge. Cards built this way are faster to review and produce more reliable recall than cards that bundle several facts, so the generated prompt enforces it explicitly.
Yes. With the tab-separated option on, the AI outputs one card per line as front, a tab, then back — the plain-text format Anki's File > Import accepts directly. You can also add a third tag column for organising the deck.
A cloze card hides a key word inside a full sentence, shown as {{c1::hidden text}} in Anki's cloze syntax. The prompt limits each card to a single deletion, because multi-blank sentences violate the one-fact-per-card rule and are harder to grade honestly during review.
A single AI response reliably holds format for roughly 40 cards; beyond that, decks get truncated or drift from the tab-separated layout. Decks up to 500 cards are therefore split into near-equal batches, and the prompt tells the AI to wait for "next" between batches.
