The problem

Your brain struggles to write and
listen at the same time.

Lectures move fast. Notes fall behind. You end up choosing between understanding and capturing — and either way, something gets lost.

Hand cramps, missed words

Writing fast enough to keep up means your notes are incomplete — or illegible.

ADHD makes it harder

Splitting focus between listening and writing is exhausting. Something always slips.

Non-native language

Following a fast lecture in your second language is double the cognitive load.

No notes = no studying

Without written notes, reviewing means watching the whole lecture again.

Our story

Built at the
kitchen table.

We're Victoria and Pierre — a couple from the south of France. Victoria is studying anthropology online — every lecture, every seminar, every workshop streamed from home. Pierre loves building things with code. This started as a side project to see if a little Chrome extension could help — and turned into something we think everyone deserves.

Victoria's days are hours of video lectures back to back. Taking notes while watching meant losing the thread. Rewinding, rewriting, rewatching. Notes too sparse to study from, or too rushed to read. On top of that, she has ADHD — which makes splitting focus between listening and writing not just hard, but exhausting.

So Pierre started building, and Victoria tested every version — broke things, gave feedback, explained what was actually missing. Evening after evening, laptop to laptop.

This is the result. We're making it available to everyone because no student should have to choose between listening and writing. If it helps you even once, it was worth it.

What it does

Everything you need.
Nothing you don't.

Accuracy you can trust

Audio is sent in chunks — 10 seconds in Normal mode, 30 seconds in Optimal for even better accuracy. A short delay, but far more accurate text than any real-time alternative.

Don't just read — work directly in the transcript. Highlight key phrases, bold terms, add headers and bullets, remove the parts you don't need. Most students finish their notes before the lecture ends.

Compatibility

Works everywhere
audio plays.

University internal platforms, protected videos, public sites — if audio comes out of your computer, we can transcribe it.

University platforms

Moodle, Canvas, Blackboard, Panopto — the ones with no download, no subtitles, and no help. If the video plays in your browser, we transcribe it.

Public video sites

YouTube, Coursera, Udemy — all the classics. But also any embedded player on any site, no matter how obscure or non-standard.

Works with headphones

AI mode captures tab audio directly from the browser — no microphone, no speakers needed. Study at 2am without disturbing anyone.

How the two modes capture audio

Free mode uses your microphone to pick up audio through your speakers. Works on every platform — but volume matters. Turn system volume up for best accuracy.

AI mode captures the browser tab audio directly, bypassing your mic entirely. Clean capture with headphones on, at any volume, on any protected platform.

Pricing

Free forever. Pay only
for what you transcribe.

Start for free with your microphone. Top up when you need AI-powered transcription — no subscription, no expiry.

Why does AI mode cost money? Free mode uses your browser's built-in speech recognition — local, instant, free. AI mode sends your audio to a state-of-the-art cloud AI model. That processing has a real cost. We pass it on transparently: credits are consumed second-by-second from your pack, they never expire, and you choose how fast you burn them based on the transcription mode you use.

Common questions

How do credits work?

Buy a credit pack and you'll receive a license key by email. Open the extension settings, enter the key, and your credits activate immediately. They're consumed second-by-second as you transcribe — nothing is wasted when you stop.

I lost my activation code. What do I do?

Check your inbox — the key was sent when you purchased. Your key is portable: it works on any computer, survives reinstalls, and your remaining credits are always preserved. Think of it as a prepaid balance, not a device licence.

My transcription is in the wrong language.

Make sure you've selected the correct language in the extension settings before starting. If you changed language mid-session, stop the transcription, select the right language, and start again. The speech engine needs a clean restart to switch languages.

The transcription isn't working at all.

Try these steps in order: (1) Make sure the extension is up to date — check for updates in chrome://extensions. (2) Reload the extension by toggling it off and on. (3) Reload the page with the video. (4) Check your internet connection — AI mode requires it. (5) If you're using mic mode, make sure your system volume is high enough (80%+) and that you've granted the extension permission to access your microphone.

Microphone mode isn't picking up the audio.

This is almost always a volume issue. Free mode relies on your mic hearing your speakers — the louder your system volume, the better the pickup. MacBook Air users typically need a higher volume than MacBook Pro users. Also make sure you've allowed microphone access for the extension.

Can I transcribe multiple videos at the same time?

Yes — but only with AI mode. AI mode captures tab audio per tab, so each video runs independently. Free (mic) mode captures whatever your speakers play, so mixing audio sources will confuse the transcription.
