What you get

🔁

Spaced repetition

Cards come back right before you forget them. Grade a card and it picks the next day for you.

📥

Bring your Anki decks

Import an .apkg file or paste a plain list. Loopky finds the separator and builds the cards.

🗣️

Listen and speak

Language decks read the card out loud and check how you say it back.

🤝

Share decks with friends

Publish a deck, follow someone else's, or clone one and make it yours.

🤖

Your AI writes the cards

Ask your AI to build a Japanese deck from the first season of Naruto. Loopky has a terminal app, so it can.

AI flashcard maker

Let your AI build the deck

Tell your AI what you want to learn, from the show you love to next week’s interview, or hand it your notes. Pick an idea, make it yours, and paste it into Claude, ChatGPT, Gemini or the agent you already use.

Hand it anything: a PDF, slides, a spreadsheet or a photo of your notes.
Works in the AI app you already use, on your computer or in the browser.
You approve the sign-in on your phone, and it only touches your decks.

Using Claude Code or Codex?

Install the Loopky plugin once. Then just ask for flashcards: it knows every step, and on Claude Code on the web it installs the CLI itself.

Claude Code

/plugin marketplace add jvsena42/loopky
/plugin install loopky@loopky

Codex

codex plugin marketplace add jvsena42/loopky
codex plugin add loopky@loopky

Read the CLI docs

Prompt for your AI

Your request

Copy adds the setup steps, so your AI can install Loopky, write the cards and publish the deck.
