Features and mini-gamesEvery Cardvoo mini-game and study tool, from Fact or Bluff and Speed Grid to Podcast, Walk & Recall and Charades, and which plan each one needs.

Fact or Bluff (Free): Swipe right for true, left for false, against a 60-second clock. Your own cards, played fast.

Speed Grid (Free): Match every term to its definition on a shuffled 4×4 grid before three minutes run out.

Two Truths & a Lie (Free preview · Standard & Pro): For each term the AI writes two real facts and one very believable misconception. Spot the lie.

Flashcard Connections (Free preview · Standard & Pro): Sixteen terms, four hidden themes. Group them the way the NYT's Connections does.

Concept Taboo (Free preview · Standard & Pro): Describe a term in your own words without using its three banned words, then an AI checks you got it right.

Charades (Pro only): A Heads-Up!-style party game: hold the phone up, tilt down for correct, tilt up to pass.

Weak-Spot Blitz (Free): One round built from your weakest cards across every deck, not just one. Play the same game formats, aimed at what you're about to forget.

Recall Race (Free for every tier): Head to head on the same deck: send a friend a link and the first to 10 right answers wins.

Cardvoo Live (Free for every tier): Host a Kahoot-style room for up to 50 players, joined by a 6-digit code or a QR code.

Study Guides (Standard & Pro): Turn your notes or your mistakes into a study guide with cited concepts and self-check questions, then export it.

Test Loop (Free): Take a test, see which topics slipped, get a guide, and retest just those until they stick.

Walk & Recall (Pro only): An audio-first review session over every due card. Put your phone away, headphones in, and let Voo quiz you.

Podcasts (Pro only): Two AI hosts turn a deck into an episode: an overview, your weak cards, or a Pop-Quiz that asks you out loud.

Snap & Occlude (Pro only): Turn a photo of a labelled diagram or a textbook page into image-occlusion flashcards.

Leech Doctor (Standard & Pro): For cards you keep failing, the AI suggests a rewrite, a split into two simpler cards, or a mnemonic.

Exam Countdown (Free for every tier): Track an exam across several decks and get a daily study plan that leads up to the date.

Study-to-Earn (Free plan): On the Free plan, careful reviewing earns extra runs of Learn, Test and the mini-games.

Leagues & Leaderboards (Free): Earn XP by studying, climb a weekly league from Bronze to Diamond, and compare scores on deck leaderboards.

Courses (Free): Share one deck with your whole class: create a course from a deck you own and hand out a 6-digit code.

Explore (Free): Search public decks by keyword and subject, and look them over before you sign up.

Voo (Free): Voo is Cardvoo's index-card mascot. Study to earn skins and accessories, all free.

Usernames & public identity (Free for every tier): A public username stands in for you on leaderboards, in Recall Race, on Cardvoo Live and on public decks.

On-device AI (Free for every tier): On the Free plan the AI model runs on your own device, so text you paste isn't sent to a cloud model.
