Study and Master
Anytime, Anywhere

Flash Deck is a modern, AI-powered flashcard application designed to make studying more efficient and effective. It uses AI to automatically generate well-structured flashcards from your text, PDF documents, or images. The app features an intelligent spaced repetition algorithm, swipe-based study interactions, and comprehensive progress tracking. Whether you're a student preparing for exams or a professional learning new skills, Flash Deck combines the power of AI with proven spaced repetition techniques to accelerate your learning.

Flash Deck uses advanced AI to automatically generate flashcards from various sources: Text Input (paste or type any text), PDF Documents (upload PDFs up to 25MB), Images (upload images or take photos up to 5MB), and AI Instructions (describe what you want to learn). The AI automatically detects the language, identifies key concepts, and creates balanced question-answer pairs optimized for learning.

Free Tier: 5 AI generations per month, 5 image scans per month, 100 manual entries per month, full access to study mode and spaced repetition, basic statistics, and CSV import. Pro Tier: Unlimited AI generations, unlimited image scans, unlimited manual entries, advanced statistics and analytics, priority support, and all free tier features.

Flash Deck uses an enhanced spaced repetition algorithm with swipe-based interactions. Swipe right when you know a card - it appears less frequently. After 3-5 consecutive right swipes, the interval increases (daily → every 3 days → weekly). Swipe left when you need more practice - the card appears more often. The system adapts to your performance, showing difficult cards more often and mastered cards less often. Study sessions are capped at 20-50 cards to prevent fatigue.

Yes! Flash Deck supports multiple import methods: CSV Import (question/answer columns), JSON Import, PDF Import (AI generates flashcards automatically), and Manual Entry (create flashcards one by one or in bulk). The import system automatically detects column mappings and validates your data before importing.

Flash Deck's study mode features intuitive swipe-based interactions: Swipe right when you know the answer - the card appears less frequently. Swipe left when you need more practice - the card appears more often. Tap any card to flip between question and answer sides. Study sessions are optimized for 20-50 cards to maintain focus. Your performance is automatically tracked to optimize future sessions. Use the speaker icon for text-to-speech auditory learning.

Yes! Flash Deck includes deck sharing functionality: Generate shareable links/tokens for your decks, make decks publicly accessible (optional), and anyone can study public decks without creating an account - just use the share link. You can also use share tokens to import decks created by others into your own account. This makes it easy to collaborate with classmates or access community-created content.

PDF Files: Maximum size 25MB, supports both text-based and scanned PDFs, AI automatically extracts and processes content. Image Files: JPG, JPEG, PNG, GIF, WebP formats, maximum size 5MB, can take photos directly with device camera, AI uses OCR to extract text. CSV Files: Standard CSV format with question/answer columns, automatic column detection and mapping.

Flash Deck includes built-in Text-to-Speech functionality: Tap the speaker icon to hear flashcard content read aloud, automatically detects language and uses appropriate voice, strips HTML formatting for clean audio output, and helps with pronunciation and auditory learning. TTS works offline using your device's built-in speech synthesis capabilities.

Yes! Flash Deck provides comprehensive progress tracking: Statistics Dashboard (overall progress, study streaks, performance metrics), Deck Analytics (statistics for individual decks), Goal Setting (set and track learning goals), Performance Insights (understand which cards need review), and Study History (track study sessions and review patterns). Pro users get access to advanced analytics and detailed insights.

Absolutely! Flash Deck takes data security and privacy seriously: Secure Authentication (Supabase Auth with industry-standard security), Data Encryption (all data encrypted in transit and at rest), Privacy First (your flashcards and study data are private by default), Account Control (delete your account and all data at any time), No Data Sharing (we don't share your personal data with third parties), and GDPR Compliant (follows data protection best practices).

Flash Deck includes a built-in dark mode feature: Go to Settings from your profile menu, switch between Light and Dark themes with a single tap, choose to follow your device's system theme preference, and your preference is saved automatically. Dark mode reduces eye strain during extended study sessions, especially in low-light environments. All features work seamlessly in both light and dark modes.

Managing your Pro subscription is easy: View subscription status in your Profile page, upgrade to Pro from Profile settings or the Upgrade page, manage subscription through the "Manage" button if you're already Pro, update payment methods through Stripe customer portal, cancel subscription at any time (access continues until end of billing period), view billing history and receipts, and subscriptions automatically renew unless cancelled. Contact support for help with subscription management.

Flash Deck uses a soft limit system for Pro users: Pro Tier: 100 AI generations/month, 100 image scans/month. Limits reset monthly and if you exceed Pro soft limits, you can contact us to request additional quota. Soft limits exist for cost control (AI services have usage costs), to prevent abuse, ensure fair usage, and most users won't hit them.
