KarlLang

KarlLang is a typing-first vocabulary trainer for adult learners.

Instead of tapping multiple choice options, you type every answer yourself. This helps build real recall, not just passive recognition.

Learn across multiple languages including German, Japanese, Chinese, Spanish, French, and more.

Features: • Typing, copy, card, cram, and Word Drop training modes • Spaced repetition (SRS) review system • Typing hints and focused repetition training • Difficult word and bookmark review • Shareable learning summary cards • CEFR-based vocabulary (A1–B2)

KarlLang is designed for learners who want to actively train memory and build real output skills through typing and repetition.
