Study on your own.
Just don't lose it.

langNote is an AI language-learning app that turns your own study material — a photo of a worksheet, a PDF, a class recording or a screenshot — into seven practice missions (podcast, dictation, shadowing, vocabulary, grammar, role-play and quiz), then schedules spaced-repetition review so you actually remember it.

Duolingo teaches its own fixed course and Anki needs you to write every card by hand. langNote starts from the material you are already studying — your class, your textbook, your worksheet — and builds the drills and the review schedule for you.

Photos of worksheets or textbook pages (PNG, JPG), PDFs, class or conversation recordings (M4A), screenshots and pasted text. You can also record straight into the app and watch a live transcript appear.

You can study English, Korean, Japanese, Mandarin, Spanish, French, German and Portuguese. The app interface itself is translated into 10 languages, so you can learn a language you barely know while reading instructions in your own.

It reads the material — including handwriting and audio — and builds seven practice missions: a podcast episode of the lesson, dictation sentences, shadowing drills, vocabulary with examples, grammar patterns explained in context, a role-play scenario and a quiz. Each item then enters a spaced-repetition schedule.

Yes. Each lesson becomes a podcast episode — two hosts talking through what you uploaded — and it keeps playing with the screen off or in the car. Shadowing and role-play also work by voice, so you can practise speaking while your hands are busy.

langNote is $10 per month, or $96 per year which works out to $8 per month. Every account starts with a 7-day free trial that does not ask for a card, so you only pay if you decide to continue.

Yes — 7 days with full access to every feature, and no card is required to start. You enter payment details only if you choose to subscribe when the 7 days are up.

Yes. Your uploads are never used to train models, files are stored in a private per-user bucket, and the links used to read them expire within minutes. You can delete your account and all its data from inside the app.

Yes for uploading and analysing a lesson, since the analysis runs on the server. Reviewing already-generated material is fast and light, but langNote is an online app.

People who already study a language somewhere else — a class, a tutor, a textbook, a drama they are working through — and lose most of it because nothing turns those notes into practice and review.
