Attach local photos and diagrams to either side of a card.
For Claude Code, Codex, OpenCode & any coding agent
A folder of files.
A rich deck back.
The AI Prompt page makes quick text-only cards in any chat. This is the other way: add one skill to your AI coding agent and it builds full JustFlip decks — with images, audio and Markdown — straight from the files on your disk. No copy-pasting, no hand-written JSON.
Add the JustFlip skill to your agent.
One command installs the justflip-create-flashcards skill into any agent that
supports skills.sh. Run it once
in your project, then just ask in plain language.
Read the skill source on GitHub before you install it →
Audio
Bundle pronunciation clips and spoken-form hints for TTS.
Markdown & math
Rich formatting, code blocks and LaTeX, rendered natively in-app.
Point it at a folder. Ask in plain words.
Say you have a folder of mushroom photos named after each species. Ask your agent to turn the file names into questions and the photos into answers — it reads the folder, builds the deck and packages the images for you.
$ ls mushrooms/
fly-agaric.jpg chanterelle.jpg porcini.jpg
morel.jpg death-cap.jpg shiitake.jpg
❯ This folder contains images of mushrooms. Take the file names as the question text and the mushroom image as the answer. Prepare the flashcards deck.

Import
It writes a .flashcards.zip. Open it with JustFlip and the deck is in.
Frequently asked questions.
How is this different from the AI Prompt page?
A chat AI can only return text, so the AI Prompt gives you a text-only .flashcards file. A coding agent can read files on your machine, so this skill returns a .flashcards.zip bundle with local images and audio already attached.
Which coding agents does this work with?
Any agent that supports skills.sh, including Claude Code, Codex and OpenCode.
Is it safe to install a skill from GitHub?
The skill's source is public — read it on GitHub before installing, the same way you would review any dependency.
What kind of media can be attached to a card?
Local images and audio clips on either side of a card, plus rich Markdown, LaTeX math and syntax-highlighted code — all rendered natively in JustFlip.
How do I open the finished deck in JustFlip!?
The agent writes a .flashcards.zip file in your project folder. Open it with the JustFlip app and the deck — with its images and audio — imports automatically.
