LangLearn

Learn A Language By Listening

Lessons and stories built from the words you already know, slowed down until you understand them. Listen on the commute or the dog walk — no flashcards, no desk.

Why Most Language Learning Does Not Stick

It needs a desk

Flashcards and drills need your eyes and your hands. Most people never find that half hour, so the app sits unopened.

The words are wrong for you

Textbook dialogues are full of words you have not learned yet, so every sentence is a puzzle instead of practice.

Real speech is too fast

Native speakers run words together. Jump straight to full speed and you hear noise, not language.

How it works

Three Steps To Your First Lesson

1Pick your languages

Tell LangLearn your first language, the language you want to learn, and the language your lessons are taught in.

2Start at your level

Choose where you are today: a complete beginner, a few hundred words, about a thousand, or ten thousand. Under a thousand words you start with the lessons; from a thousand you start with ready-made stories at your level.

3Press play and listen

Listen, listen again, then start repeating — the order you learned your first language in. Start slow and speed up as each story becomes familiar.

Inside LangLearn

Everything You Get Once You Sign In

Every screen is built around one habit: pressing play and listening.

A course taught in your language

Two short training lessons, then levels of twenty audio lessons each. You choose the language the lessons are taught in, and every new word comes with its meaning in it.

A player made for the road

Slow down or speed up, jump back or forward one sentence, repeat a story or a whole playlist, or shuffle it. Pauses in the lessons give you time to repeat and to answer.

Download it, listen offline

Save any playlist to your device and it plays with no connection — on a plane, in the metro or out on a trail.

Your progress at a glance

Your dashboard shows how many words you know, your estimated fluency and the words you are learning right now. Ask for new words only when you are comfortable with these.

Every word you know, ranked

Each word shows its meaning, how common it is and the lesson it came from. Mark one as unknown and generate new stories with it until it sticks.

Stories and conversations on demand

Pick a level, a length and up to ten stories at once — or a two-person conversation with its own voice for each speaker. Your Claude or ChatGPT writes them; LangLearn checks them and reads them aloud.

What we guarantee about every story

  • Every word comes from the words you already know, plus the handful of new words the story teaches — nothing else, not even names.
  • Every new word comes with its meaning in your first language.
  • You can hold every sentence to one new word at most, so you never have to guess twice at once.
  • Each story is checked word by word against your list before it is saved, and comes with its audio.
  • Nothing is marked as learned behind your back — you decide when you know a word.

Questions Learners Ask

Is LangLearn really free?

Yes, for now — as long as you sign in and use it at least once a week. An optional paid plan adds even better story audio.

Which languages can I learn?

The app lists every language that is ready today. If yours is missing, you can request it from that same list.

Do I need an AI assistant?

No. The lessons and ready-made playlists work on their own. Connecting Claude is optional: it lets your AI write new stories at your exact level.

Do I have to install anything?

No. LangLearn runs in your browser on a phone or a computer. An Android app is in early access on Google Play.

I want to learn English. Is this for me?

Yes. English learners have their own page: english.ctoteachings.com.

Can I listen without a connection?

Yes. Download any playlist to your device and it plays offline, with the text of every story.

What do my level and fluency percentage mean?

Your level is your place in the language's word list, ranked from the most used word down: level 800 means the 800 most common words. The fluency percentage beside it is an estimated app milestone, not a formal language assessment.

Can I listen to stories other learners made?

Yes. Stories generated by every learner are in one shared library, and you can add any of them to your own playlists.
