What they are
Podcastle
Podcastle, recently rebranded as Async, is a browser-based audio and video production platform aimed at podcasters and solo creators. It handles remote recording, AI-powered noise removal, transcription-based editing, and voice cloning in one workspace. The free tier covers basic recording but caps exports and AI features. Paid plans start around $11.99 per month, making it competitive with dedicated tools like Descript for audio-first workflows.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
