Overview

Castos is podcast hosting and distribution, with two AI capabilities that address the work surrounding an episode rather than the recording itself.

Transcripts are generated for every episode automatically. That matters more than accessibility alone – a transcript is the only way podcast content becomes searchable and indexable, and audio is otherwise invisible to search entirely. The AI Assistant then handles what Castos calls the tedious part of podcast marketing: producing the show notes, titles and promotional copy that every episode needs and that most independent podcasters skip once the novelty wears off.

Around that sit podcast analytics, hosted podcast websites, private and commercial feeds, and a mobile app, with tiers for enterprise and agency use. It is a complete hosting platform rather than an AI tool with hosting attached – the AI is the layer that makes consistent publishing sustainable.
