Record language lessons straight from the browser

July 7, 2026

People using LingoChunk don't upload much of their own audio. I think I know why, because I feel it too, so I built a browser extension to take the faff out.

Something I noticed in how people use LingoChunk: not many of them upload their own audio. Most stick to what’s already there.

I have a guess about why, and it’s the same thing that trips me up in my own studying. Getting your own audio into the app is more of a faff than it should be. To feed in my own material I’ve leaned on a couple of separate tools to capture the audio, then uploaded the file by hand. None of it is hard on its own. Together it’s the sort of small hassle that quietly stops you bothering.

So I built a browser extension to take that step out.

Recording a lesson in the browser

It records the audio straight in the browser and sends it into the app. If the lesson is playing in a tab, a tutor on a call for instance, it records that tab and your microphone together, so both sides land in one recording. In person, it records the microphone on its own. One button to start, one to stop, and it goes into LingoChunk ready to become a transcript you can pick apart word by word and shadow.

There’s an auto-stop, so you can set it to your lesson’s length and forget it, and an option to email you when the transcript is ready. It records to your own machine, and nothing leaves until you send it.

What it saves you

No separate capture tool, no file to dig out, no manual upload. The thing you wanted to keep is already in the app by the time you’ve finished listening to it, which for me is the whole difference between doing it and meaning to.

It’s a browser extension for Chrome and Firefox. Recording another tab’s audio is a Chrome feature, so on Firefox it’s microphone only, which still covers an in-person lesson or recording yourself.

You can install it from the Chrome Web Store. It’s open source too, so the code is on GitHub if you’d rather load it yourself or just see what it does.
