Flashcards that live inside Moodle, built on the Leitner box method.

LeitBox turns any course material into a deck of flashcards learners can practise on their own — six learning boxes, fast AI-ready card creation for teachers, and no data ever leaving your Moodle server.

Moodle Marketplace listing: coming soon

LeitBox dashboard with six learning boxes and an overall progress bar — Six-box dashboard: New, Beginner, Learner, Advanced, Experienced, Expert — with overall progress at a glance.

Flashcard front side showing a question and an optional hint — The question first — with an optional hint if a learner gets stuck.

Flashcard back side with the answer and three rating buttons — Flip the card, then rate yourself: Got it, Again, or Hard. A single mistake never resets all progress.

Bulk import screen with a ready-to-use AI prompt template — Copy a ready-made prompt into any AI assistant, then paste the result back in to import a whole deck at once.

Card management table listing every flashcard with edit and delete actions — Manage every card in a simple table — edit, delete, or export the whole deck as text.

What LeitBox is for

Named after Sebastian Leitner, the Austrian scientist who invented the flashcard box method in 1972. LeitBox brings that method natively into Moodle — no extra login, no external tools.

Cards in minutes, not hours

Bulk import from a simple text format, plus built-in prompt templates for six question types — paste your material into any AI assistant and import the result directly, no CSV, no file upload.

Nothing gets lost

A wrong answer moves a card back exactly one box, never all the way to the start. Cards and progress are included in standard Moodle course backups.

No external services

All flashcards and learning progress stay on your own Moodle server. No third-party login, no external API calls, no tracking.

Calm by design

No ranking, no leaderboards, no game points, no images on cards — built for focus and memory rather than competition.

Features

For teachers

Two ways to create cards: type them one by one, or paste a whole deck at once using a simple text format — including decks written by an AI assistant from a ready-made prompt. Full card management table with edit, delete and export. Three combinable completion conditions tied to Moodle's Activity Completion system.

For learners

Six learning boxes from New to Expert, three simple rating options per card, an optional hint, and a calm, distraction-free interface with no ranking or competition. Practise at your own pace — there is no fixed schedule.

Six ready-made question templates

Each template comes with its own copy-paste AI prompt, so a teacher can turn existing material into a finished deck in minutes:

Standard Q&A (factual knowledge)
True or False (with explanation)
Vocabulary & Terms (translations, definitions)
Fill in the Blank (cloze-style)
Jeopardy (answer first, guess the question)
Transfer & Real-World Application (highest didactic level)

Three completion conditions

Combine any of these with Moodle's Activity Completion system:

Learner has interacted with a minimum number of unique cards
Learner has promoted a minimum number of cards to Expert level
Learner has promoted all cards to Expert level

Quality and privacy
