## Flashcards (32 Cards)

| # | Front (Term / Prompt) | Back (Definition / Answer) | Example | Multiple-Choice Options |
| :--- | :--- | :--- | :--- | :--- |
| 1 | How do you batch-generate Neural TTS audio or local M2M-100 translations for an imported 500-card CSV deck? | Select the deck, open Batch Actions, and run local M2M-100 translation or enable offline MOSS Neural TTS voice synthesis across the deck's language pair. |  |  |
| 2 | How do the 'Quick-Reference Tables' and 'Sample Cards' in Flashcards.world Study Guides connect to the interactive app? | Every module in a Flashcards.world Study Guide embeds direct one-click links (`/flashcards/sets/<set_id>/`) that open that exact 32-card deck inside the interactive 11-mode study app. |  |  |
| 3 | If a PDF page contains a high-yield comparison table (e.g., Gram-Positive vs. Gram-Negative bacteria), how does the AI PDF Generator convert it? | It decomposes each contrasting row of the table into separate atomic discrimination cards rather than dumping the entire table onto a single unreadable card. |  |  |
| 4 | Why do duplicate flashcards hurt your FSRS-6 spaced repetition accuracy if left uncleaned? | If the exact same question exists twice as Card A and Card B, seeing Card A today artificially boosts your short-term recall when Card B appears 2 days later, corrupting the independent Retrievability ($R$) calculation of both cards. |  |  |
| 5 | How does the 'Visual PDF Page Picker' work when you upload a PDF textbook or lecture slide deck to Flashcards.world? | Instead of blindly processing an entire 500-page PDF (including table of contents, blank pages, and bibliographies), the Visual PDF Page Picker renders thumbnail previews of every page so you can click or drag-select the exact high-yield pages (e.g., Pages 42–55) to convert into flashcards. |  |  |
| 6 | Why is 32 cards per set the ideal modular deck size in Flashcards.world? | A 32-card set takes exactly **10 to 15 minutes** to complete in a focused Pomodoro session—large enough to cover a full syllabus module thoroughly, yet compact enough to finish in a single sitting with zero fatigue. |  |  |
| 7 | What are the 4 ways to create or import a full flashcard deck in Flashcards.world without typing every card manually? | 1. **AI PDF-to-Flashcards** (with Visual Page Picker); 2. **AI Notes / Text-to-Flashcards** (paste lecture notes or outlines); 3. **Universal File Import** (Anki `.apkg`/`.colpkg`, Excel `.xlsx`, `.csv`, `.tsv`, `.txt`); 4. **Curated Library & Topic Generator**. |  |  |
| 8 | How does Flashcards.world handle Anki's `{{c1::answer::hint}}` Cloze Deletion syntax during `.apkg` import? | It preserves Anki's `{{c1::…}}` and `{{c2::…}}` cloze syntax natively (or converts them seamlessly to interactive Tap-to-Peek Cloze pills) so every cloze card works immediately upon import. |  |  |
| 9 | What happens inside Flashcards.world when you upload an Anki `.apkg` archive? | The importer unpacks the ZIP container, reads the internal SQLite database (`collection.anki2` / `collection.anki21`), extracts all Notes, Cards, and Media files (images & audio), and maps them into your Flashcards.world deck. |  |  |
| 10 | What configuration parameters can you set before running the AI PDF or Notes-to-Flashcards generator? | 1. **Target Card Count** (e.g., 15, 30, or 50 cards); 2. **Difficulty / Expertise Level** (`basic`, `intermediate`, `advanced`); 3. **Card Style** (Atomic Q&A, Cloze `[…]`, Bidirectional `⇄`, or Exam Vignettes); 4. **Front & Back Output Language**. |  |  |
| 11 | How does the AI Generator avoid creating 'Yes/No' or bloated paragraph cards when converting your PDF? | Its prompt engineering enforces Piotr Wozniak's Minimum Information Principle—requiring concise, unambiguous cues on the Front and atomic 1-to-15-word core answers on the Back. |  |  |
| 12 | How can you export your Flashcards.world decks for backup or sharing with classmates? | Export any deck as JSON, CSV/TSV, Excel, or share a direct deck link (`https://flashcards.world/flashcards/sets/<set_id>/`) so classmates can open and study the exact same curated set immediately. |  |  |
| 13 | How does the 'AI Notes / Text-to-Flashcards' workflow work for students taking live lecture notes in Notion, Obsidian, Google Docs, or Apple Notes? | Copy your raw bulleted lecture notes or markdown outline, paste them into the Notes-to-Deck box, choose your card count and difficulty, and review the generated atomic cards in the staging preview before saving. |  |  |
| 14 | How does the 'Anki Multi-Field Mapper' work when importing a complex Anki note type that has 6 fields (e.g., `Expression`, `Reading`, `Meaning`, `Sentence`, `Audio`, `Notes`)? | The import wizard displays all detected fields from the `.apkg` note template with live sample values and lets you choose which field(s) go on the **Front**, which go on the **Back**, and which map to the **`💡 Mnemonic` / Extra Notes** field! |  |  |
| 15 | How can you use the AI Generator to create 'Bilingual or Cross-Language Flashcards' from an English PDF? | Set the source PDF input in English and select your desired target language (e.g., Spanish, German, Japanese, or Hindi) for the Front or Back output—or use the on-device M2M-100 translator. |  |  |
| 16 | How do you merge two or more smaller decks into a single unified master deck in Flashcards.world? | Select the decks in your library (or use 'Import into Existing Deck'), assign a source tag to each sub-deck (e.g., `#week1`, `#week2`), and run Duplicate Cleanup so all cards share a single interleaved FSRS-6 queue. |  |  |
| 17 | Can the AI PDF-to-Flashcards generator extract concepts from both native digital PDFs and scanned/slide PDFs? | Yes—it parses digital text layers directly and extracts structured definitions, mechanisms, tables, and numerical values from lecture slides and textbook pages. |  |  |
| 18 | How do you use 'Paste from Quizlet / TSV Copy-Paste' to migrate a deck in 10 seconds? | Export or copy your term/definition pairs separated by tabs (`\t`) or semicolons and paste them directly into the Bulk Import box in Flashcards.world—creating a full deck instantaneously. |  |  |
| 19 | Can you choose whether to import or reset existing scheduling history when importing an Anki `.apkg` deck? | Yes—you can either start the imported deck fresh as unseen cards OR convert existing review intervals and ease factors into initial FSRS-6 Stability ($S$) and Difficulty ($D$) states. |  |  |
| 20 | How does Flashcards.world handle HTML tags (`<b>`, `<i>`, `<br>`, `<ul>`, `<img src="...">`, `[sound:...]`) inside imported Anki cards? | It automatically sanitizes and converts formatting tags into clean Markdown/rich text, links extracted images to the card's visual slots, and binds `[sound:...]` references to the card's audio player. |  |  |
| 21 | Summarize the fastest 60-second workflow from a 50-page lecture PDF to a live FSRS-6 study session. | 1. Upload PDF → 2. Select key pages in Visual Page Picker → 3. Choose 32 cards & `intermediate` level → 4. Quick-audit in Staging Preview → 5. Save & launch Flashcards Mode with FSRS-6. |  |  |
| 22 | Can you append newly generated AI cards from Chapter 2 directly into your existing Chapter 1 deck? | Yes—choose 'Add to Existing Deck' in the AI Generator staging view and tag the new batch `#ch2` so your deck grows progressively across the semester. |  |  |
| 23 | What character encoding does Flashcards.world use for all CSV/Excel/Anki imports to ensure CJK, Arabic, Cyrillic, and math symbols never corrupt? | Full UTF-8 Unicode encoding (with automatic BOM detection for Excel CSVs), preserving Kanji, Hangul, Arabic diacritics, Devanagari conjuncts, and mathematical symbols without mojibake. |  |  |
| 24 | How does the 'Interactive Column Mapper' work when importing an Excel (`.xlsx`) or `.csv` file? | After uploading your spreadsheet, you preview the first 5 rows and map which column corresponds to `Front`, `Back`, `Mnemonic / Hint`, `Tags`, and `Category / Level`—with a toggle to skip the header row. |  |  |
| 25 | What Anki file formats can be imported directly into Flashcards.world? | Both standard Anki Deck Packages (`.apkg`) and Anki Collection Packages (`.colpkg`), including decks exported from desktop Anki, AnkiMobile, and AnkiDroid. |  |  |
| 26 | What spreadsheet and text file formats does the Flashcards.world tabular importer support? | Microsoft Excel workbooks (`.xlsx`, `.xls`), Comma-Separated Values (`.csv`), Tab-Separated Values (`.tsv`), and structured plain text files (`.txt`) with custom delimiters. |  |  |
| 27 | What is the 'Duplicate & Near-Duplicate Card Cleaner' during deck import or deck maintenance? | An automated deduplication tool that scans your deck (or across multiple decks) for identical or near-identical Front prompts (ignoring case, whitespace, and punctuation) and lets you merge, keep newest, or delete duplicates in one click. |  |  |
| 28 | How do you verify that an imported deck has zero empty fronts, zero empty backs, and zero front==back errors? | The built-in Deck Validator automatically checks every imported card for non-empty Front/Back fields, strips trailing whitespace, flags any card where Front equals Back, and warns of duplicate prompts. |  |  |
| 29 | What happens if a CSV file uses semicolons (`;`) or pipes (`\|`) instead of commas (`,`) as column separators? | The Flashcards.world CSV/Text importer auto-detects the delimiter (`,`, `;`, `\t`, `\|`) and lets you override it manually with a live table preview before importing. |  |  |
| 30 | What is the '6-Set Progressive Curriculum Matrix' structure used by official Flashcards.world study guides? | Every flagship exam or subject topic is structured into 6 progressive 32-card decks (192 cards total): Modules 1–2 (`basic`), Modules 3–4 (`intermediate`), and Modules 5–6 (`advanced`). |  |  |
| 31 | Why is selecting specific page ranges in the Visual PDF Page Picker far superior to whole-file PDF dumping? | 1. It skips cover pages, references, and fluff; 2. It keeps each generated deck aligned to a single coherent lecture or chapter (~25–40 atomic cards); 3. It maximizes AI extraction density on every selected page. |  |  |
| 32 | What is the 'Staging Preview & Audit Step' right after the AI generates a deck from your PDF or notes? | Before saving the deck, Flashcards.world shows all generated cards in an editable preview list where you can tweak wording, delete any unneeded card, toggle Reverse `⇄`, or add a `💡 Mnemonic`—ensuring 100% quality control. |  |  |
