Are the AI-generated cards accurate?

We engineer the AI prompt for exam-grade accuracy: every card must have a non-empty, factually correct back; no placeholder text; no tautological cards (front equals back); all fronts within a deck must be unique. Every response runs through a server-side validator that drops cards which fail those checks, and if zero usable cards survive validation, the server makes one corrective retry before returning an error. We still recommend skimming the deck once before high-stakes study — AI is a strong assistant, not infallible.

Is Quick Cards free? Do I need to sign up?

Yes, completely free. No signup, no email, no credit card. We do not write your deck to a database — Quick Cards is anonymous and browser-local by design. If you want to save and re-study a deck across days, FlashDeck Builder (Phase 2) will offer that with optional account creation, but Quick Cards itself will always stay anonymous.

Can I study in dark mode?

Yes. Quick Cards has full light and dark mode support with explicit color pairs on every surface (no auto-derived washed-out tones). Use the Sun/Moon toggle in the header. The card itself has separate indigo (front) and purple (back) gradient backgrounds tuned for readability against both themes.

Can I study on my phone?

Yes — the entire experience is mobile-first. Cards fill the viewport on phones, tap targets meet WCAG 2.5.5 (minimum 44×44 px), and you can swipe up on the card to flip in addition to tapping. The modal sticks to the bottom of the screen on phones (iOS-style sheet) and centers on tablets/desktop.

What keyboard shortcuts does Quick Cards support?

Space or Enter = flip the card. 1 / 2 / 3 / 4 = rate Again / Hard / Good / Easy (only active when the back is showing, so you cannot accidentally rate before reading). H = reveal the hint when one is available. F = toggle Focus Mode (browser fullscreen + hidden chrome). Esc = exit Focus Mode.

Can I save my deck and share it with classmates?

Yes — after finishing a session, tap Save & Share on the Summary screen. SpinWheelGo creates an anonymous, shareable URL (e.g. spinwheelgo.com/d/p4q8m2j6z3) that any device can open to study the same deck. Saved decks are kept for 24 hours, then auto-purged — no account, no email, no PII required. Use it for study groups, classroom drills, or just to re-open your own deck on a different device later in the day.

How long are shared decks kept?

24 hours from creation. After that the deck is automatically and permanently deleted by Firestore's TTL sweeper — there is no way to recover it. This is the same anonymous-retention pattern as Live Audience Survey, intentionally short to keep the feature lightweight and privacy-friendly. Permanent deck storage with cross-day spaced repetition arrives in Phase 2C (FlashDeck Builder), which will require optional account creation.

Can I edit, reorder, or add cards to my deck before studying?

Yes — tap Edit deck on the Summary screen to open the manual editor. You can rewrite any card's Front, Back, and Hint in place, reorder cards up and down, delete cards, and add brand-new ones (up to 100 per deck). Per-field caps mirror the backend save schema. Hit Save and study to restart the deck with your changes. If you opened the deck from a /d/ share link, your edits stay local until you tap Save and Share again — that mints a new share URL so the original link you sent to friends stays stable.

Will a shared deck link show a rich preview when pasted in iMessage, Slack, or WhatsApp?

Yes — every /d/ URL returns Open Graph and Twitter Card meta tags built from the actual deck title and a snippet of the first card-fronts. iMessage, Slack, WhatsApp, Discord, LinkedIn, Twitter/X, and Facebook all render a preview card with the deck title and a short description, not just a bare URL. Backed by a tiny Cloud Run endpoint with a five-minute crawler cache so viral shares stay snappy without hammering the database.

Can I upload a PDF, Word document, or PowerPoint and turn it into flashcards?

Yes — Phase 2C-lite (May 26 2026) added a Document tab to the Quick Cards INPUT screen. Drop or pick a PDF, DOC/DOCX, PPT/PPTX, ODT/ODP, RTF, TXT, or MD file up to 25 MB and AI builds a deck from the actual document content (headings, key terms, callout boxes) rather than generic knowledge of the topic. An optional focus hint (e.g. 'only Chapter 3') narrows card selection to a specific section. Files are processed in an isolated per-request workspace and deleted right after the response — no retention.

Can I export my deck to Anki, Quizlet, or a spreadsheet?

Yes — Quick Cards offers a Download CSV button on the Summary screen. The CSV is in the Anki / Quizlet two-column convention (Front,Back,Hint) with UTF-8 BOM and RFC 4180 escaping, so it opens cleanly in Excel, Google Sheets, Numbers, LibreOffice, Anki, and Quizlet. Native Anki .apkg export will follow in Phase 2C.

Q: What subjects can I make flashcards for?

Anything you can describe in a sentence. Common use cases: K-12 (math, science, history, geography, civics, English, languages), college and grad-school subjects (engineering, biology, economics, law, computer science, medicine, finance), standardized exam prep (SAT, ACT, GRE, GMAT, LSAT, MCAT, AP exams, IB, NEET, JEE, UPSC, CFA, FRM, PMP, USMLE, Bar exam, Praxis), tech certifications (AWS Cloud Practitioner / Solutions Architect / Developer / SysOps, Azure Fundamentals / Administrator / Architect, GCP ACE / Professional, CompTIA A+ / Network+ / Security+ / CySA+, Cisco CCNA / CCNP, Kubernetes CKA / CKAD, ITIL, Scrum / PSM / CSM, Six Sigma), languages (vocabulary, grammar, conjugation drills in English, Spanish, French, German, Italian, Portuguese, Mandarin, Hindi, Tamil, Arabic, Japanese, Korean, Russian, and dozens more), medical study (anatomy, physiology, pharmacology, drug names, MOA, side effects), legal study (case names, statutes, definitions), corporate training (onboarding glossary, compliance, security-awareness, product knowledge, sales playbook), continuing education (medical CME, legal CLE, teacher PD), and hobby trivia (sports, music, film, pop culture, gaming, history).

Q: How does the 4-rate study queue work?

Quick Cards uses a Leitner-lite session scheduler. After you flip a card you rate how well you knew it: AGAIN (sent to the back of the queue and shown again before the session ends), HARD (reinserted ~5 positions ahead so you see it again soon), GOOD or EASY (mastered for this session — removed from the queue). The session ends when every card has been rated GOOD or EASY at least once. It is the same '4-rate' pattern made popular by Anki and Quizlet, simplified for an in-browser single-sitting flow.

Q: How is Quick Cards different from Quick Quiz?

Quick Quiz is a 4-option multiple-choice quiz with a correct-answer key — best for fact-recall and exam-style assessment. Quick Cards is a flashcard deck with front/back study cards — best for memorization, vocabulary, definitions, formulas, languages, and any topic where the learner needs to recall an answer rather than recognize it from 4 choices. They share the same AI engine but have completely separate prompts, validators, controllers, and study UX.

Type a topic. AI builds a real flashcard deck. Tap to flip, rate Again / Hard / Good / Easy, and the queue loops missed cards back until you've mastered every one. Light & dark mode, mobile-friendly, zero signup.

How is Quick Cards different from Quick Quiz? ▾

Quick Quiz is a 4-option multiple-choice quiz with a correct-answer key — best for fact-recall and exam-style assessment, especially when you want a graded shareable link. Quick Cards is a flashcard deck with front/back cards — best for memorization, vocabulary, definitions, formulas, languages, and any topic where the learner needs to recall an answer rather than recognize it from 4 choices. They share the same AI engine but have completely separate prompts, validators, controllers, and study UX. Use both together: skim the cards to learn, then quiz yourself to verify.

Can I save my deck and study it later? ▾

Not in Phase 1 — Quick Cards is single-sitting and browser-local by design (anonymous, no Firestore write). Cross-session deck saving will arrive in Phase 2 (FlashDeck Builder) with optional account creation, spaced-repetition scheduling, sharing, and progress tracking. If you need a permanent record today, screenshot the deck after Generate or finish the session and capture the per-session summary.
