From real classrooms
I'd been looking for these features for a couple of years. I'd built parts of this myself, but never to the level KOKU offers. I feel closer to my students now, and honestly, I feel like a better teacher.
Honestly, I was so excited for KOKU's launch, and I can't recommend it enough. As an online teacher, it's a real time saver. I can track all my students and see where they're heading. It improves my teaching overall.
KOKU takes my lessons to a whole new level. All my students love the platform. They can't wait for their recaps and to see their progress in English with me. If you haven't tried KOKU yet, you have no idea how much time you could be saving.
Across every lesson
Lesson Studio reads all of a student's lessons together: their level, the mistakes that keep coming up, what's improving, and what to do next.

Lucas is progressing toward confidently handling job interviews and workplace conversations, especially around experience and achievements. He is consolidating core grammar for talking about work and practicing interview-specific structures, with growing fluency and some lingering grammar pitfalls.

We spent the hour on contrast — although, even though, though — and then took it into the restaurant scene you asked for. You reached for although three times unprompted, and put it in the right half of the sentence twice.
The corrections below are nearly all about where the clause sits: although opens one of the two halves, it never stands between them the way but does. Worth a slow read before the homework.
The food was expensive, although. Although the food was expensive, we stayed.
although joins two halves — only though can be left at the end of a sentence
I am agree with you. I agree with you.
agree is a verb on its own in English, so it takes no am
We are living here since 2019. We have been living here since 2019.
since + a starting point takes the present perfect, not the present
Can you explain me the bill? Could you explain the bill to me?
explain never takes the person straight after it — the thing first, then to me
We started from the sentences you wrote last week and joined them up, one pair at a time.
Although the restaurant was full, they found us a table.
Contrast first, result second — the order that sounds most natural.
Pattern: Although + [clause], [clause].
Note: although and but do the same job, so one sentence never needs both.
Your answers, recorded here and saved with the lesson.
You caught two of your own mistakes today before I said anything — that is new. Next lesson we take the same contrast into writing: a short review of somewhere you liked but would not go back to.

Every word from your lessons, split by what kind of word it is. Cards you get right come back later; ones you miss come back today.
Recap, corrections, vocabulary, audio, flashcards and every chart — built from the recording, none of it typed by the teacher.
The recorder
Lesson Studio records from inside your browser. No bot joins the call, nothing is installed on your student's side, and nothing leaves your laptop until you press send.
You'll need Google Chrome. It's a Chrome extension — free, one click from the Web Store, and it works on Mac, Windows and Linux. Not Safari, not Firefox.
Student
Records this tab and your mic on separate tracks.
What you get
Teach as usual. The extension records, the draft writes itself.
Every recap waits in your queue until you approve it.
Every word from the lesson becomes a flashcard, due the day it would slip.
Lessons, vocabulary, homework and audio — in one place, under your name.
Scores, talk time and vocabulary chart themselves.
Reading, writing and speaking — built from what you actually taught.
Languages
Type the language you teach. Twenty-seven of them come back as a full write-up, with vocabulary, corrections and a practice test.
Set per student, so you can teach two of them at once.
All twenty-seven, and the same twenty-seven a learner keeping their own journal can pick from.
The arithmetic
A teacher with twenty students. Four lessons each this month, at $30 a lesson. Here is the whole month — one dot per lesson.
Every one of those 80 lessons comes back written up — recap, vocabulary, homework, progress — for less than 2 of them earn you.
Pricing
Three recaps free, no card. Then one plan a month, pause or cancel any time. A recap costs less than what you charge for two minutes of a lesson.
Every plan includes
Reviewing, editing and re-sending a recap never uses one up.
Questions
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.
Any lesson that happens in a Chrome tab: Zoom in the browser, Google Meet, Preply, italki. No bot joins the call.
To record, yes: Google Chrome on a Mac, Windows or Linux computer. Your students open their recaps on any phone.
No. They get a link to their own portal, and nothing is installed on their side.
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.
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.
3 recaps free. No card. Your first lesson comes back already written.
