A session, step by step

  1. Meet a new word

    A word page with the meaning in English, a short definition, example sentences with audio, and related words. Some concrete words get a picture too.
  2. Check it right away

    A quick question follows straight away, and the word comes back a few questions later in a different form.
  3. Reviews arrive just in time

    The app predicts when you're about to forget each word and brings it back right then: not too early, not too late.
  4. Questions get harder as you learn

    First you recognize the word, then pick it, then use it in a sentence, and finally type it from memory.

Reviews right before you forget

Every word has its own memory model. When the chance you'd remember it drops to 90%, it comes back. Each review makes it last longer, so you spend your minutes on the words that need them.

Why it works

Questions

Is it really free?
Yes. LenguaLearn is free for learners and teachers, with no ads and no selling data. It runs on a small budget on purpose.
Who is it for?
English speakers learning Spanish: independent learners aged 13 and up, and Spanish classes from first year through AP and college.
How much time does it take?
Sessions are 15 minutes by default, and teachers can change that. Learning comes from showing up most days, so a short session every day beats a long one once a week.
Where do the words come from?
Each word page is drafted with AI and checked field by field by a second, independent AI. Then a person reviews and approves it: nothing reaches a student before that. See how content is made.
Does it work on Chromebooks and phones?
Yes. It's a web app built and tested at Chromebook and phone sizes, and every action works by keyboard and by touch.
