SignalCast is a podcast-summary service that helps listeners keep up with new episodes without having to listen to every one. Users choose from more than 200 curated podcasts or add any show with a publicly available RSS feed. SignalCast uses Claude AI to process episode transcripts and create concise summaries focused on key arguments, insights, frameworks, notable quotes, and practical takeaways. Each summary links to the original episode, making it easy to check details or continue listening.

The free plan includes one show and access to a weekly digest by email and on the web. Digests are delivered every Monday, bringing selected episodes together in a brief designed to help users decide what merits a full listen. The Pro plan costs $5 per month and includes up to five shows, with a choice of daily, weekday-only, or weekly delivery. SignalCast presents its service as a way to reduce podcast backlogs and start the week better informed, while clarifying that summaries are intended to support listening decisions rather than replace full episodes.
