Lorebyte

Lorebyte is a flashcard app built on FSRS spaced repetition — designed for language learning and certification study. Review at the optimal moment, right before you forget.

◆ Science-based spaced repetition (FSRS)

• The modern FSRS algorithm picks what to review next
• Just rate each card: Again / Hard / Good / Easy
• Done for the day? Keep going in Practice mode without affecting your schedule

◆ AI-generated flashcards

• Paste text or import a PDF/photo, and AI drafts flashcards for you
• Runs fully on-device via Apple Intelligence on supported devices — nothing leaves your device
• Or bring your own API key (OpenAI, Anthropic, OpenRouter, and more) for cloud-powered generation
• Review and edit every generated card before saving

◆ Create cards fast from your materials

• Import from PDFs, photos, and screenshots (English/Japanese OCR)
• Bulk import from CSV and plain text with automatic format detection
• Optional Japanese translation aid for English study text (on-device)
