The problem
Your brain can't 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.
Who made this
Built for
online students.
Victoria is studying for a bachelor's in anthropology at a French university — entirely by distance, with ADHD. Hours of video lectures, workshops, seminars every week.
Taking notes while watching meant losing the thread. Rewinding, rewriting, rewatching. Notes too sparse to study from, or too rushed to read. The cognitive load of listening and writing at the same time, with ADHD, is brutal.
Pierre is a geek. So he started building. Victoria tested every version, gave feedback, broke things, explained what was missing. Weeks of iteration — a real back-and-forth.
This extension is the result. We hope it lets you focus on what actually matters — understanding what you're learning, not fighting to write it down.
Who it's for
Built for people who learn by reading along

University lectures, online courses, MOOCs — capture everything without losing the thread of what's being said.
Free mode works greatADHD Learners
Reading along while listening dramatically reduces cognitive load. Stop losing focus mid-lecture.
Accessibility firstOnline Course Takers
Udemy, Coursera, YouTube tutorials — turn any video into searchable, editable notes automatically.
Any video siteLive editing
Edit while you watch.
Highlight in 5 colors, bold key terms, add headers and bullets — turn a raw transcript into study-ready notes without leaving the video.
What it does
Everything you need.
Nothing you don't.
Accuracy over speed
Audio is chunked into 10-second windows (3 seconds optimal) — exactly how the AI model was trained. The trade-off: a short delay, but far more accurate text than any real-time alternative.
Rich note editing
Format your transcript as it arrives — highlight key phrases, bold important terms, add bullet points, and toggle headers on the fly.
Export anywhere
Download as .txt or .md, or copy to clipboard. Your notes, your format.
14 languages
English, French, Spanish, Arabic, Hindi and more. Transcribe in the language of your lecture.
Privacy first
Everything stays local by default — no account, no cloud processing in free mode. Your audio, your data.
Timestamps + history
Optional timestamps on every line. Resume past sessions without losing your work.
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 Premium cost money? Free mode uses your browser's built-in speech recognition — local, instant, free. Premium 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.
Free
Uses your browser's built-in speech engine and your microphone. Fully local — no audio sent anywhere.

Premium — Pay as you go
Buy a pack once. Your hours are consumed second-by-second as you transcribe — nothing is wasted when you stop. Time shown is for Normal mode. Live mode sends audio more frequently and burns ~3× faster. The extension shows your live burn rate so there are no surprises.
Works with headphones on. Tab audio is captured directly — no microphone, no speakers needed.

Common questions answered.
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.
What is player sync?
Player sync is a beta feature for Premium users. It links the transcript to the video timeline — when you click a line in the transcript, the video jumps to that moment. When the video plays, the transcript follows along. It works best with standard HTML5 video players.
What are the premium formatting features?
Premium unlocks additional formatting tools: text highlighting with colours, toggling section headers on and off, and hiding/collapsing parts of your transcript. These work on top of the free editing features (bold, bullets, auto-save) and are designed for students who want to turn a raw transcript into study-ready notes.
