Babbel doesn't teach Esperanto, and it teaches no other made language. Duolingo does teach Esperanto, and its course is covered in Is Esperanto on Duolingo?
Esperanto is a language made on purpose, and L. L. Zamenhof published its first book in 1887. Each letter has one sound, and six letters carry marks: ĉ, ĝ, ĥ, ĵ, ŝ and ŭ. Reading apps, tutors and more are in our best apps to learn Esperanto.
Bubblegum
For serious learners, Bubblegum is the best app to learn Esperanto. You learn from Esperanto you can mostly understand, which is called comprehensible input.
Tell Poppy, your AI tutor, your level and what you like, and she writes your Esperanto lessons. If a sentence is hard to follow, ask Poppy to explain it.
With Regenerative Review™, words you save show up again in new lessons, so that you can review words in new contexts without having to use flashcards.
When a long word stops you, such as malsanulejo (hospital), ask Poppy to split it into its parts and say what each part adds.
- Poppy writes each lesson for your level, on topics you pick.
- Each lesson plays AI audio while you read.
- Tap a word to see what it means, or ask Poppy to explain a whole line.
- Grammar topics explain how Esperanto works, such as the -n on a direct object.
- Regenerative Review™ brings saved words back in new lessons, and you can export them to Anki.
- Clear, expressive AI voices read every lesson aloud, with a different voice for each speaker.
- You can't turn your own Esperanto books or articles into lessons. However, you can paste a page in the chat, and Poppy will explain it.
- Bubblegum has no practice tests for the Esperanto language exams.
- Custom lessons cost us money to make, so you need Bubblegum Pro for unlimited custom lessons. Lessons Poppy wrote for other learners are free for everyone to read.

Which Esperanto app should a beginner choose?
If you are serious about learning Esperanto, start with Bubblegum. Poppy, your AI tutor, writes lessons at your level about things you like. Or start with the free lessons on Lernu, which are made for Esperanto only.
Do I need to learn special letters first?
No. You learn the six letters with marks as the words appear, because each letter has one sound. A long word like malsanulejo (hospital) is built from parts, and Bubblegum's Poppy can split it and say what each part adds.
Is Bubblegum free?
Yes. Lessons Poppy wrote for other learners are free for everyone to read. Custom lessons cost us money to make, so you need Bubblegum Pro for unlimited custom lessons.
