About this app

MemoMammoth helps you learn words from real content.

Read TXT files, select words, check their meanings, and save them with example sentences. You can also learn from videos by tapping subtitle words and saving them to your deck.

Saved words can be reviewed later with quiz-based practice, helping you build vocabulary from the content you actually read and watch.

Main features:
- Read TXT files
- Save words with meanings and examples
- Learn from supported video subtitles
- Translate selected text or subtitles
- Review saved words with quizzes
- Sync learning data when signed in

MemoMammoth is built for language learners who want to study naturally through texts, subtitles, and videos.
