    Custom Lessons Made for You

    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.

        Common Questions

        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 Duolingo course, or 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.
