Some apps give away a whole course, and others give away a reader, a word game, or a chat partner.
The 15 apps below are sorted by what they help you do.
Lessons Poppy Writes for You
Bubblegum
Bubblegum is the best app for serious learners. You learn from text and audio you can mostly understand, which is called comprehensible input.
Bubblegum teaches 60 languages, including Korean, Portuguese, Swahili, and Icelandic, and its menus come in 74 languages. Poppy, your AI tutor, makes every lesson fit your level.
If you want to study a text you picked yourself, try Readlang or LingQ further down.
- Pick a topic you care about, like cooking or a trip, and the lesson is about that.
- Tap any word for its meaning, and ask Poppy about grammar that puzzles you.
- Save a word, and Poppy puts it into a later lesson so you read it again. That's Regenerative Review™.
- Clear, expressive AI voices read every lesson aloud, with a different voice for each speaker.
- It can't turn a book, article, or show you found into a lesson.
- A new custom lesson costs us real money to make, so your first one is free, and Bubblegum Pro gives you unlimited custom lessons. The lesson library is free for everyone, because we believe everyone should be able to learn.
