Want to understand someone? CastMind gathers their interviews from wherever they are, so you can follow them and publish what you took away. To understand Karpathy today, you dig through Lex for one episode, Dwarkesh for another, and YouTube for his own long videos. Podcast apps can't help — they subscribe by show, so search gives you shows, not the episode he was on. CastMind works by person. — What it does for you — · Gather one person Tap + on Listen and search podcast episodes, Bilibili, and YouTube by name. Select a batch, keep them in one collection, and put them in your own order. The collection is pinned to Deep Dive on Home. · Tap a line to understand it When an English interview has a transcript, tap a line to understand it on the spot, or turn on bilingual view. If the show publishes its own transcript, it's fetched when you open the episode; YouTube and Bilibili can pull platform subtitles. · A transcript even when there isn't one Download a podcast episode and make a transcript on this iPhone. Audio never leaves the device. I ran a 3-hour-32-minute Chinese interview (210 MB) on iPhone 15 Pro Max — about 6 minutes to a full draft. It's machine dictation, so expect typos; the bar stays labeled unproofread. · Traces that leave themselves Mark a moment from the lock screen, Control Center, Siri, or your headphones without opening the app. Lines you tapped and moments you marked land in the same place. · Write a teardown you'll sign What you marked is laid out in the episode's teardown. You only write your own take. One Markdown file per episode, ready for X or your blog. · Pick up where you left off Open and continue from your last position. Each show remembers its speed; Smart Speed skips silences and Voice Boost lifts voices. Bind shows you follow to a smart collection and new episodes land there automatically. · On runs, commutes, and in the car Lock screen, Control Center, and headphone controls are ready. In the car, open CastMind on CarPlay to continue a podcast, open a show, or play a collection. · Offline first Original text, marks, and notes are readable and editable offline. No account. Nothing uploaded to the cloud. — What we deliberately don't do — No recommendation feed, charts, or people directory — you search for the person you already care about; we won't scroll content at you. No pronunciation scoring, no flashcards, and AI never writes your take for you. castmind.ai is CastMind's website.
