Joe Rogan Experience #1470 — Elon Musk

Press play — that is the episode on YouTube, with the panel it produced: 58 references, each at the second it was said. Scrub, and the panel follows.

The catalogue

We keep a short list
of shows indexed.

3 of these are indexed already, so the panel is filled in before you press play. The rest are queued. Anything else with captions you can index yourself — it takes a few minutes and then it is there for everyone.

    Where it goes wrong

    Why not just summarise it

    A summary is somebody
    else's paragraph.

    What a summariser hands you

    In this wide-ranging conversation, the guest discusses ancient history, archaeology and the origins of civilisation, touching on several controversial theories before turning to his own research and recent book.
    • A model decided what mattered.
    • Nothing in it is a link.
    • Nothing in it is a timestamp.
    • The book is "his own book". You still don't know the title.

    What the panel hands you

      • No model picked the highlights. You do.
      • Every line is a link to a public record.
      • Every line is a second in the video.
      • The book is The Sign and the Seal, by Graham Hancock.

      Every mention in a two-hour episode, plotted.

      Every dot is something named, at the second it was said. A line means two of them came up inside the same ninety seconds.

        If the episode is indexed, the references are there. If it is new, the panel offers to index it, and takes a few minutes.

      Where the words come from

      Nothing in the panel
      was written by a model.

      Every description is copied, word for word, from a public record — and the link to that record sits under it. The models find what was named and where. They do not describe it, rate it, or check it.

      What Mentionaut looks things up in
      RecordWhat it answersIn #2530

      An episode uses what it needs. #2530 is archaeology and scripture, so almost everything resolves to one encyclopaedia. An episode about training and longevity leans on PubChem and MedlinePlus instead, and barely touches Open Library.

      98 of the 182 things named in this episode have no link.

      They are still listed — the name and the second it was said. What they do not get is a description or a link, because nothing matched confidently enough. A wrong link is worse than no link, so we leave it blank.

      No link means we could not match it. That is worth knowing too.

      Before you install

      The questions we get.

      What does it cost?
      Installing is free. Indexing an episode nobody has done yet costs you one of five free runs a month. Reading an episode someone else already indexed is always free.
      Which shows does it work on?
      Any YouTube video with a caption track, which is nearly all of them. It is not restricted to a list of approved podcasts.
      What if nobody has indexed the episode I'm watching?
      The panel offers to index it. It takes a few minutes, and once it is done it is there for everyone who watches that episode afterwards.
      Will it slow YouTube down?
      No. One card in the sidebar, one request per video. It never touches the player or the video stream.
      Which browsers?
      Chrome and Brave. Other Chromium browsers — Edge, Arc, Vivaldi — should work. Firefox and Safari are not supported yet.
      Will it tell me when someone is wrong?
      No — and it is built so it can't. It shows what was named and links the source. What you make of the claim is yours to decide.
      Can it see my browsing?
      It runs on youtube.com and nowhere else, and reads the video identifier. It keeps no record of what you watch unless you switch history on yourself.

      Everything found so far

        What it adds up to

        Every episode leaves something behind.

        A book you'll actually read. An idea you keep coming back to. A name you would have lost by morning. Mentionaut catches them while you listen, so the hours add up to something you can go back to.
