Flashcards with an AI companion who remembers what you're learning

How flashcards work inside Bondi

In Bondi, flashcards aren't a separate app you have to remember to open — they're one of 15 activities that run inside conversations with your AI companion. You pick a deck, whether that's Spanish vocabulary, a knowledge topic, or one of the alphabet packs (hiragana, katakana, cyrillic, arabic or pinyin), and review right there in the chat. Under the surface it's classic spaced repetition: a Leitner system that moves each card through boxes as you answer, showing you difficult cards more often and mastered ones less. A session takes a few minutes. You see a card, answer, and move on — with your companion right there in the same chat between rounds. Your progress is tracked per deck, so you can always see how far a set has come — and because it all happens with someone rather than in a silent grid of buttons, coming back tomorrow feels less like a chore.

Why memory changes revision

Spaced repetition already relies on memory — the algorithm's memory of your cards. Bondi adds a second kind: your companion's memory of you. Bondi's AI characters remember what matters across conversations, so the companion you review flashcards with knows which deck you've been working through and what you're learning the language for in the first place. That context changes the experience. Instead of a cold streak counter, you get someone who can pick up where you left off, connect today's cards to last week's conversation, and encourage you in a way that actually reflects your journey. And that memory is yours to manage: every item your companion keeps can be read, edited, exported or deleted from your account whenever you wish.

More than a standalone flashcards tool

A standalone flashcards app does one thing, and when your motivation dips, there's nothing holding you there. Bondi's flashcards live inside a wider companion — over 300 hand-crafted AI characters, with an interface available in 14 languages. If you're learning a language, the decks sit alongside the Language Academy: structured lessons from A1 to C2 in ten languages, with grammar, vocabulary, reading and writing skills, script lessons for Japanese, Chinese, Russian and Arabic, and explanations in your own language. You can drill vocabulary as flashcards, then use it in real conversation with an AI character who speaks the language. And because the same companion is there for your other activities — journaling, habits, planning a trip — studying becomes part of an ongoing relationship rather than an isolated app on your home screen.

Your first deck is free

Flashcards are part of Bondi's free plan, and the Pro subscription is exactly what it says — optional. Nothing to pay up front, no countdown, no card. Once you've met your AI companion, open your first deck. If you're starting a language, the alphabet packs are a gentle first step — hiragana or katakana for Japanese, cyrillic for Russian, arabic script, or pinyin for Chinese. From there, the Leitner system quietly does its work: a short review most days beats a long cram once a week, and Bondi's per-deck progress tracking lets you watch cards move towards mastered. Bondi is available on the web now; apps for iOS and Android are rolling out. Ready to try flashcards with someone rather than something? Find my Bondi — start free.
