Use tool ↗About Flexi Cards
Flexi is a mobile flashcard app that generates vocabulary cards automatically instead of asking you to write them by hand. For a given word it can produce up to five related cards with translations, example sentences, and audio pronunciation across more than twenty languages, then schedules reviews with a spaced-repetition algorithm. It can import existing decks from Anki, Quizlet, or a CSV file, and includes an AI chat mentor for asking about a card's content. The base app and CSV import are free; a Premium subscription at $5.99 a month (or $29.99 a year, or $99.99 once for lifetime access) unlocks the AI tutor chat and importing from Anki or Quizlet. It's a solo indie project by developer Tomer Beilinson, not a company.

Pros & cons of Flexi Cards
Flexi is a capable AI-assisted flashcard app for people who already keep vocabulary decks in Anki or Quizlet and want AI to fill in translations, examples, and audio automatically. It's mobile-only, so it won't suit anyone who studies at a desktop.
Pros
- Auto-generates up to five card variants per word with audio
- Supports over twenty languages
- Imports existing Anki/Quizlet/CSV decks
- Real user traction — tens of thousands of installs and a high app-store rating
Cons
- Anki and Quizlet import is locked behind Premium, not free
- iOS and Android only, no web app
- Solo-developer project with no visible support team
Best for
- Language learners who want auto-generated card content instead of typing it
- People migrating existing Anki or Quizlet decks
- Users who want audio pronunciation built into review sessions
Not for
- Anyone wanting a web or desktop version
- Users who don't want a subscription for tutor chat or deck import
Watch out: The 7-day free trial converts to a recurring charge automatically unless cancelled first.
