For private language teachers

An AI assistant for one-to-one language teachers

Lesson Studio records your online lesson and drafts what comes after it: the recap, the vocabulary, the homework and the progress. You approve it, and it lands in your student's own portal.

What you get after every lesson

  • A recap of the lesson, drafted from the recording a few minutes after it ends.
  • Every word that came up, as flashcards due the day they would slip.
  • Your student's mistakes, quoted back with the correction beside them.
  • Homework and practice tests built from what you actually taught.
  • Progress that charts itself: talk time, vocabulary and scores.
  • A portal for each student, under your name.

You stay in charge

Nothing reaches a student until you approve it. Every recap waits in your queue, and editing or re-sending one never uses up a recap.

How it differs from a meeting note-taker

  • No bot joins the call. A Chrome extension records the lesson tab and your microphone.
  • Two separate tracks, so it knows which words were yours and which were your student's.
  • Made for language learning: vocabulary with readings, corrections, flashcards and tests, not action items.
  • Written for the student, in the language they read best.

27 languages

Japanese, Korean, Mandarin Chinese, Cantonese, Vietnamese, Thai, English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, Czech, Ukrainian, Greek, Turkish, Arabic, Hebrew, Hindi, Indonesian, Swedish, Norwegian, Danish, Finnish. Where the script is not the Latin alphabet, every word comes back with a reading beside it.

Questions

Does it work for group lessons?

No. Lesson Studio is built for one-to-one lessons: one teacher, one student. The recorder hears your microphone and the call as two tracks, so with several students on a call their voices share one track and the recap cannot tell who said what.

Which lesson platforms does it work with?

Any lesson that happens in a Chrome tab: Zoom in the browser, Google Meet, Preply, italki. No bot joins the call.

Do I need a computer?

To record, yes: Google Chrome on a Mac, Windows or Linux computer. Your students open their recaps on any phone.

Does my student need to install anything?

No. They get a link to their own portal, and nothing is installed on their side.

Do I have to tell my student I am recording?

Yes. Ask for their agreement before you press record. Some countries require everyone on a call to consent, and Preply and italki have their own rules about recording.

What happens to recaps I don't use?

Plan recaps are for the month you pay for, so they don’t carry over. Away for a while? Pause your plan for up to three months and nothing is charged. Top-ups never expire.
