Frequently asked questions
Short answers about what VoiceCards does, how it compares, and where data lives.
- What is VoiceCards?
- VoiceCards is a mobile flashcard app for memorization. Users put question-answer pairs into a Google Sheet, then study them on iOS or Android. The app reads cards aloud (TTS) and grades spoken answers (STT). It supports Speak mode for active recall and Listen mode for passive review, and can generate cards from a prompt or photo via AI.
- How is VoiceCards different from Anki?
- Anki stores cards in its own database; VoiceCards stores them in the user's own Google Sheet, so editing on a laptop is just opening Google Sheets — no third-party desktop app, no sync conflicts. VoiceCards also defaults to a voice-first study loop (speak the answer, hear the card) rather than typed or tapped recall, which suits language learning and verbal recall better than text-heavy SRS.
- How is VoiceCards different from Quizlet?
- Quizlet is study-set marketplace + multi-mode learning; VoiceCards is opinionated about one workflow (your sheet, your cards, voice in/out) and adds AI card generation from prompts or photos. There is no marketplace and no social/share-set feature — content is private to the owner's Drive unless they share the sheet themselves.
- Is it free?
- Core features (importing a sheet, Speak mode, Listen mode with the device's built-in TTS, statistics, study reminders) are free. Premium TTS voices and AI card generation use a per-request credit. New users get a starter grant of credits.
- Which languages are supported?
- Card content can be in any language Google Sheets accepts. Recognized TTS/STT languages include Korean, English, Japanese, Chinese (Simplified), Spanish, French, German, Italian, Portuguese, Russian, Vietnamese, Thai, Indonesian, and Arabic among others. The app UI is localized to 7 languages.
- Where is my data stored?
- Cards stay in the user's own Google Drive — VoiceCards does not keep a duplicate copy on its server. Learning statistics (attempts, accuracy, streaks) and per-card metadata live on Supabase, scoped to the signed-in user.
- Does it work offline?
- Cached cards and previously synthesized TTS audio play offline. New AI generation, premium TTS synthesis, and fresh sheet imports require a connection.
- Who is it for?
- Language learners, students prepping for exams, professionals studying certifications (e.g. CDL, medical, civil service), and anyone who memorizes question-answer pairs as part of their routine.
