Start free
Every student gets 30 videos with transcripts and chaptered summaries, no card. Pro gives 100 videos a month and playlist import.
Got a code?
Student papers, societies and lecturers we work with have codes for Pro free until the end of the year.
One paste, a whole course
Paste the module's playlist link and the lectures import in batches. Each one gets a transcript and a chaptered summary while you get on with something else.
Timestamps that jump to the moment
Chapters come from the real transcript, each with a timestamp. Click one and the player seeks straight to it — revision without scrubbing.
Search every lecture at once
Half-remember a definition, a formula, a case name? Search your whole library and land on the second it was said, in whichever lecture it was.
Lecture recordings with no captions
Most lecture uploads have captions and cost nothing to transcribe. For one that has none, an on-demand AI transcript is available — the first two are free, then it's credits-billed.
Start with these

Questions
How do I get free Pro?
With a code from a student paper, society or lecturer we work with. Click their link or type the code above; it is applied when you sign up, by email or with Google. Each code has its own number of places.
Do I need a card?
No. The free plan needs no card, and neither does Pro from a code. There is nothing to cancel; at the end of the offer the account returns to the free plan.
What happens to my library at the end?
It stays. Everything you saved remains searchable. Adding more videos beyond the free plan's 30 needs Pro — £3.99 a month in the UK, $4.99 elsewhere.
Does it work for a whole YouTube course?
Yes — paste the playlist link. Pro imports it in batches of 5 videos, and each lecture gets its own transcript and chaptered summary.
Can I share notes with my course group?
Any video in the community library can be published as a public notes page you can send to anyone, no login needed to read it.
