Field notes for your brain

Stop watching. Start keeping.

Any long-form YouTube video becomes a structured course: modules, recall questions, a confidence-sorted review queue, and a notes margin that fills up as you go. Quoted by length, from $5.99.

STEP 1
Paste a link

Any long YouTube video. You see the price — quoted from the video’s length — before anything runs or costs a cent.

STEP 2
Approve the outline

We propose the modules; you rename, merge, or split them. Nothing is built until you say so.

STEP 3
Learn it, keep it

Real questions on every module — and the ones you miss come back as different questions until the idea sticks. Your notes live in the margin.

The notebook grades you back.

You rate your confidence before every answer is revealed. What you got confidently wrong becomes its own review list — the page most worth rereading. Miss it, and a different question on the same concept comes back until you get one right.
