Drop in any lecture, podcast or talk. Get back four layers of knowledge — an enriched article, the principles, the mental models, and key ideas for recall.
Richard Feynman · Lecture · 9 min read
Feynman frames discovery as a loop: you guess a law, compute its consequences, then compare with nature. If it disagrees with experiment, the guess is wrong.
A guess is a provisional law proposed before its consequences are known — judged only by whether its predictions survive experiment.
Guess → derive consequences → test against nature → keep or discard. The loop is indifferent to authority and beauty.
No amount of elegance rescues a theory that disagrees with experiment. Evidence outranks intuition.
Predictions, not prestige, decide whether an idea stands.
An idea earns trust by surviving honest attempts to break it.
The law is a model of nature, never nature itself.
The loop that turns a hunch into knowledge.
Experiment overrules elegance and authority.
No setup, no notes-app gymnastics. Paste, wait less than a minute, and start learning.
Drop in any lecture, podcast, talk or interview — long-form is exactly where it shines. That's the whole setup.
It works through the full transcript — not a clip — and builds a structured, color-coded article in under a minute.
Every article feeds a personal knowledge base you can search across — principles and models, all in one place.
A summary tells you what was said. We extract how it works, why it's true, and what to remember.
The full talk rewritten as a clean, readable article with color-coded definition, mechanism, example, pitfall and takeaway boxes.
The underlying rules that make the topic work — each paired with the reasoning chain that justifies it.
The transferable abstractions you can carry to new problems — named, defined and ready to reuse.
The handful of points worth remembering, written for spaced recall so they actually stick.
Everything turns watching into a library you can actually use.
Principles and mental models from every video you process, aggregated and browsable in one place.
Key terms are highlighted with hover tooltips, so you never lose the thread on jargon.
Find an idea by meaning, not just keywords, across everything you've saved.
Read the article in your language regardless of the video's original language.
Classic, Nocturn and Dark — comfortable reading day or night.
Send any article to a friend with a single private link.
This is a real article in the public library — generated from a full talk, not hand-written.
