No card needed.

One paste, a whole course

On Pro, 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, so you revise 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 billed in credits.

Start with these

Courses already in our library. Each one has notes for every lecture and one search across all of them.

Questions

Do I need a card?

No. The free plan needs no card, and there is nothing to cancel.

What happens when I reach 30 videos?

Your library 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.
