## What is CastKeeper For Podcasts?

CastKeeper is the podcast app that thinks with you — and keeps what you'd otherwise lose. Ask Siri AI anything about your podcasts in plain language, get transcripts that read like a real conversation, and archive any episode permanently, independent of the podcast's own feed. Free to download, free to use, no subscription ever. Never lose an episode again. Podcasts vanish — feeds get pruned, shows get pulled, back catalogs disappear overnight. CastKeeper lets you archive any episode permanently, independent of the podcast's own feed.

A GREAT EXPERIENCE FROM PEOPLE WHO LOVE PODCASTS:
Ever CastKeeper user gets a great experience, including:
- Archive and save the podcasts you love. Free users can archive up to 10 episodes to iCloud Drive.
- Subscribe, listen, and collect your podcasts in a beautiful native user interface that puts your podcasts first.
- No ads. Period. There's already enough ads about mattresses and supplements in your episodes, so we kept it out of the UI. 
- Complete privacy. No logins, no analytics. What you listen to is your business.
- Discover new podcasts and search for anything, powered by Siri AI and fully private.
- Full audio and video podcast support with picture-in-picture and audio only mode 
- Full Spatial Audio support and EQ.
- Silence Trimming and Loudness Normalization
- Cross-device sync. Listen to your favorite podcasts and archives on any supported iPhone, iPad or Mac. 
- CarPlay Support
- Siri Intents and Shortcuts Support. Play, archive, queue, and more with just the sound of your voice.

TAKE YOUR EXPERIENCE TO THE NEXT LEVEL WITH CASTKEEPER UNLIMITED:
With a one-time purchase, take your experience to the next level. No subscription, no recurring charges. Share it with your family group. CastKeeper Unlimited enhances your podcast experience with:

- Deeper, more intelligent Smart Summaries. Know before you listen not just what the episode is about, but why it is important.
- Archive across multiple different storage providers. CastKeeper Unlimited allows users to save their podcasts to other storage locations besides iCloud Drive. Use Dropbox, S3, Cloudflare R2, Backblaze B2, or even your own S3-compatible server. 
- Recap before you resume. Forgot where you left off, CastKeeper will catch you up and tell you exactly what was being discussed before resuming.

NATURAL LANGUAGE SEARCH POWERED BY SIRI AI
Type or say what you're after — "episodes about the American Revolution" or "recent episodes about grief, nothing religious" — and Siri AI searches your library and the broader podcast catalog, ranked by relevance with a reason for every match. Siri AI can also generate chapters and a Smart Summary for every episode automatically, and polishes every transcript — filler words removed, punctuation fixed, proper nouns corrected. All of it free, for everyone, on-device.

PODCASTS ARE FOR EVERYONE: 
CastKeeper includes full accessibility options for all users, including:
- Live Captions. Turn on Live Captions and CastKeeper will automatically caption any episode in real-time. 
- Dyslexia font 
- High-contrast mode
- Mono audio mode

Siri AI requires iOS 27 or later.

### 5/5 — This is a have to have

*2026-08-21*

I don’t have to worry about losing great podcasts if the channel or podcasts are no longer available.

### 5/5 — Awesome App

*2026-07-19*

Fabulous app and great support from the app developer. Easy transcript export just what I was looking for youtube integration if possible would be great and so much potential for the future road map please keep up the great work.

**Developer response:** Thank you for the review and glad you’re loving the app. Unfortunately, Google’s YouTube restrictions make it difficult to fit our model, but definitely in the research folder. 

Look forward to even more new features soon! And welcome to our community of users!

### 5/5 — Feature Requests and Bug

*2026-05-17*

Hello, I really like this podcast app. It is the best podcast app that I have found and I really like the UI. 

I just bought the app. Whenever I go to download an episode, the progress bar reaches 100%, but then the episode says that it is not downloaded and it shows that I can download it again. I click the download button and it does the same thing. 

Also, when clicking the transcribe or generate chapter buttons, they stay greyed-out, and nothing resolves. I’m unsure if this depends on the podcast episode being downloaded or not, but the transcription and generate chapter buttons do not seem to work. I don’t know if they have progress bars to monitor them, but if they do not, could you add that feature?

EDIT: I did figure out that I needed to enable “AI Processing on Battery”. However, I am still unable to generate chapters on battery. Even if it is not recommended for one to do this, could you add the ability for one to do so? Also, I’m unsure if the SOTA models are less intensive. 

Also, I have bought the podcast app Aisten as well. It does a wonderful job in transcribing podcast. It uses the SOTA V1, V2, and V3 engines to transcribe the podcasts. I was wondering if you could also add these as options to select to do the transcriptions? 

It also has a feature to both bookmark (saved only when viewing that specific podcast) and favoriting (a global way to view all favorites across all podcast) different lines of texts within the transcription. Could you add a feature similar to this? It would also be nice to have bookmarks for specific time codes. It would be nice to have a way to add notes to time codes, as well as having a note section for the given episode. I would like to use this app to do a little research. 

Another feature that would be cool is to be able to export a selected segment of the podcast’s audio. 

Thank you for your efforts. This podcast app is amazing. If there are other features I think of, I will update my review. 

Thanks

**Developer response:** Thank you so much for your feedback, and that you enjoy CastKeeper! 

Your feedback and suggestions for features are wonderful, and I will be looking at these suggestions and seeing how to incorporate them into a future release. CastKeeper was made for podcast enthusiasts like yourself, and your feedback will certainly be evaluated and put in my backlog for review. 

Be sure to keep an eye out for updates to not miss any of the new features and fixes! Thank you!
