What's New in CastKeeper

2026.5.3

August 16, 2026

INTRODUCING SMARTKEEP — YOUR INTELLIGENT ARCHIVER Never miss archiving an episode again. SmartKeep is CastKeeper's fully automatic archiver, completely at your control. Head to any subscribed podcast in your Library, enable SmartKeep, choose your storage destination, and let it run. Four options to fit how you collect. Zero effort to keep collecting and full sync across your devices! Love an episode and never want it to disappear? Lock it. Episodes locked by SmartKeep stay in your archive forever — and every episode you archive manually is always locked by default. Your storage, your podcasts, your rules. SmartKeep is included with your one-time purchase — no subscriptions, no ongoing costs. We'd rather see people collecting podcasts than collecting subscriptions. Other improvements in this release: • Smart Summaries for episodes start faster • AI Chapters tuned for better chapter names and more accurate markers • Fixed an issue where transcription and AI Chapter generation would queue unexpectedly when a device was connected via USB-C • General UX refinements and performance improvements

This is a have to have

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

Awesome App

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.

Response from developer

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!

Feature Requests and Bug

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
