## What is CastMind?

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.

## Version history (last 5 releases)

### 1.6.1 — 2026-10-24

CastMind 1.6.1
• On New, swipe right for Want to Listen, left to dismiss. Picks expire if you don’t touch them; pressing play moves them to unfinished.
• On-device transcripts queue one at a time and keep going in the background; progress shows on the Lock Screen, and you can cancel.
• Paste an X post with native video to listen; collect a batch from an account’s media page; ended Space replays import as podcasts and can download for on-device transcription.
• Bilingual lines on the podcast detail page too; the current line follows along while you listen.
• Resume shows whether this trip fits, how much is left, and the line where you stopped; resume after a pause steps back a little.
• Active subscriptions refresh in the foreground (starred first). If you have picks, New opens on Want to Listen.
• A cold-launch headphone play resumes the episode you left.
• Fixes: dismissing Bilibili detail no longer crashes; deleting the episode that’s playing stops playback cleanly.

Thanks for sticking with us. Suggestions are always welcome.

### 1.6.0 — 2026-10-13

ContextEcho is now CastMind — the same name as castmind.ai. The name on your Home Screen becomes CastMind. Your library, saved moments, downloads, and settings stay right where they were. Nothing to do, and collection QR codes you already shared still work.

Also: video lengths follow your speed — when it isn’t 1×, the original length is struck through. YouTube and Bilibili videos imported from search now show their length. Going back while a video is playing no longer crashes. If Bilibili login leaves you on its web page, or you close the sheet, the app notices you’re signed in and fetches the subtitles.

Thanks for sticking with us. Suggestions are always welcome.

### 1.5.4 — 2026-09-27

• No official transcript? Download the episode and make one on this iPhone. Audio never leaves the device. I ran a 3-hour-32-minute Chinese interview on iPhone 15 Pro Max — about 6 minutes to a full draft.
• Tap a line while listening to understand it on the spot. Bilingual view translates the lines on screen, not the whole episode up front.
• If on-device transcription misspells a name, fix that line, then check other spellings in the episode that look like the same name.
• When the show publishes its own transcript, opening the episode fetches it. No extra tap.
• Connect CarPlay to keep listening, and to see Shows and Collections.
• Listen is now Continue, Deep Dive, and New. Search someone, start a topic, and it pins to Deep Dive.
• Each show remembers its own speed. Set a sleep timer and playback stops when time's up.
• Search this episode's transcript and tap a hit to jump there. Jump far, and you can go back to where you were.
• Episode notes and chapters show on the player. Shows splits into listening and paused.
• With a large library, Home, Shows, and Learning Stats open without a pause. Capturing This Moment from the lock screen is faster too.

Thanks for sticking with us. Suggestions are always welcome.

### 1.3.0 — 2026-08-06

• Search podcasts by name when you add content — and Bilibili or YouTube too. No more hunting for links to paste.
• Open a result to preview, then decide whether to subscribe. Getting to a show you want takes fewer steps.
• Smart collections: pick the shows you follow, and new episodes land automatically. Less manual tidy-up.
• Share a collection as a poster with a QR code. Friends scan it and get the same collection in their app.
• Filter by guest on a show page or in Inbox; search names when the list is long. Easier to find the episodes someone was on.
• Open a transcript while listening: copy a line, mark a moment, or loop a sentence — without guessing by ear alone.
• Sort Inbox by recently added so new imports don’t get buried under older updates.
• Mark an episode as listened when you’re done — no need to replay just to change the status.

Thanks for sticking with us. Suggestions are always welcome.

### 1.2.4 — 2026-07-22

Open Home and your starred shows now live in Following: what's new, where you left off — one glance and you're caught up. Every podcast card lays out an episode outline: three chapters sampled from the beginning, middle, and end. Skim them first; if it's worth your time, tap in and start playing from that very second. If not, swipe past — no guilt attached.

Also in this release: Bilibili keeps playing on the lock screen, playback speed fine-tunes from 0.1x to 3.0x, thoughts and transcripts export to Markdown in one tap, downloads can stay Wi-Fi-only, and downloaded files get their own management page.

No algorithmic recommendations. No manufactured anxiety. You chose your subscriptions — you should choose what to play, too. Miss nothing. Pile up nothing.
