What we build

Leitner Learner is a web application for studying vocabulary and phrases with the G5 five-box Leitner method. You choose a learning language and a translation language. Cards can include definitions, examples, and synonyms when you add them.

Correct answers promote a card one box. Misses return it to Box 1. Scheduling is driven by the G5 review queue rather than fixed calendar intervals.

How to use the app

• How spaced repetition works — explains the G5 method in plain language.
• Pricing — the learning engine is free, with a shared limited AI allowance in the initial release.
• Install — add the app to your home screen as a PWA.
