Turn YouTube into flashcards without transcribing a thing.
A ClipMark card is a moment, not a paragraph you retyped. Save the timestamp, write a line (or let the on-device AI draft it), and you have a card whose answer is the video itself, playing from the exact second it came from.
Why making cards from video is normally so slow
The standard route is manual: pause, scrub back a few seconds, retype the point into a card app, invent a question, and — if you're diligent — paste a link so you can find the moment again. Five minutes of admin per card, on top of watching. Anyone who has tried it on a full lecture series knows how that ends.
The transcription step is the part that isn't actually doing anything for your memory. ClipMark drops it. The card keeps a pointer to the source instead of a copy of it, which is both faster to make and better to review — you check yourself against the real explanation rather than against your own hurried paraphrase.
Three keystrokes to a card
- 01
Alt+B while it plays
The timestamp is saved silently — no dialog, no pause. Keep watching; come back to the side panel when the section ends.
- 02
Add the prompt, or let AI draft it
Type the line you want to be asked about, or let ClipMark draft a note from the transcript around that second using Chrome's built-in on-device model. Any
#wordbecomes a tag. - 03
Enrol it for review
Enrolled cards enter the recall schedule — 1, 3, then 7 days, doubling to 60 — with your note hidden until you have answered.
A video flashcard has something a text card can't
The answer is the footage
Reveal replays the exact second. You are corrected by the lecturer who explained it, in the words and diagrams that made it land.
Made in seconds
No transcription step, so the marginal cost of one more card is a keystroke — which is why the habit survives past week one.
Kept in context
Cards stay grouped by video and tag, so a card never arrives stranded without the lecture it came from.
It works on whatever you actually watch — a conference talk, a pharmacology lecture, a three-hour podcast, a framework tutorial you'll need again in six months. Anything with a timeline can carry cards.
Cards, decks, and what free covers
Saving bookmarks is unlimited on Free and stored locally. Enrolling them as recall cards is capped on Free at 25 standing cards and 30 reviews a month; Pro makes both unlimited and adds cloud sync so a card made on your laptop is due on your desktop. Free also includes 10 Anki exports a month, and Pro makes that unlimited.
Can it build cards from a summary or transcript?
Partly, today. ClipMark drafts the note for a card you've saved from the transcript around that timestamp, so the text is written for you — but you choose the moments, one card at a time. There is no bulk “generate 40 cards from this whole video” step, and deeper transcript features (permanent transcript archiving and search inside transcripts) are marked coming soon on the pricing page rather than shipped. Choosing the moments yourself is the part worth keeping anyway: a card you decided mattered is one you will actually answer.
Four things we refuse to get wrong.
The player stays clear, the free tier stays honest, the permissions stay narrow, and the thing that makes it stick is built in.
Lives in the side panel, not on top of your video
ClipMark opens in Chrome’s own side panel beside the player. Nothing floats over the video, nothing covers the controls, and YouTube’s keyboard shortcuts keep working — ClipMark only claims Alt+B to save, and [ / ] to step between clips while you’re actively revisiting.
A free tier with the numbers printed on it
Free means unlimited bookmarks stored locally, on-device AI notes, 25 Active Recall cards, 30 reviews a month, and 10 Anki exports a month — no card, no trial clock. Those are the real limits, listed on the pricing page rather than discovered after you install.
Two hosts. That’s the whole permission list
ClipMark asks for youtube.com and clipmark.mithahara.com — its own sync domain — and nothing more. It cannot read your banking tab, your email, or any other site, because it was never granted them. AI notes run on Chrome’s on-device model, so transcripts aren’t shipped anywhere for that.
Your note is the question. The clip is the answer.
Tools that quiz you on a video generate the questions themselves, from the transcript. ClipMark does the opposite: it hides the note you wrote and replays the exact second, so you check your own recall against the source. Every saved moment goes on a schedule — 1, 3, then 7 days, doubling up to 60. That retrieval loop is the product, not a bullet point.
