CastNova is a web-based platform designed for coaches, consultants, and founders who produce weekly podcast episodes and want to efficiently repurpose their content for multiple online channels. The tool enables users to transform a single 30–60 minute podcast episode into over 15 pieces of content, including LinkedIn posts, Twitter (X) threads, standalone tweets, newsletter drafts, SEO-focused blog articles, and Instagram captions. All generated content is written to match the creator's own voice, aiming to avoid generic or templated outputs.
The process begins when users upload either an audio or video file of their podcast episode. CastNova uses Whisper AI to transcribe the episode in approximately 60 seconds. Following transcription, the platform analyzes the content to extract key quotes, hooks, and stories, which then serve as the basis for generating diverse posts tailored to each supported platform. The tool promises a turnaround of about three minutes from upload to final content, significantly reducing the manual effort typically involved in repurposing podcast material for social media and blogs.
Examples provided on the platform demonstrate outputs such as Twitter threads with multiple tweets, standalone tweets, LinkedIn posts referencing specific episode segments, newsletter drafts summarizing key insights, SEO-optimized blog posts, and Instagram captions. The service emphasizes that all content is ready to copy and publish, and that users retain full ownership of their generated material, with the ability to copy, download, or export their posts at any time. There is no lock-in, and cancellation can be done with a single click.
CastNova is currently in open beta and offers a free trial for new users, allowing them to upload their first episode without requiring a credit card or commitment. The platform highlights its transparency by stating that all demo content is generated from real, CC BY-licensed podcast episodes using the same pipeline available to users. This approach is positioned as a solution for creators seeking to save time—reducing what would be hours of manual repurposing to just minutes—while maintaining the authenticity of their voice in every post.
