Overview
Podcastle (now Async) is a recording-first studio. You record remotely with a guest, capturing each speaker on a separate track, then clean up the audio with noise reduction and AI tools, transcribe it, and cut clips. It has 1,000+ AI voices in 15+ languages, text-to-speech, AI dubbing, and Revoice, which clones your voice on paid plans. In early 2026 it rebranded to Async (async.com) and repositioned around video, describing itself as a chat-based AI creative suite for video content production, so audio podcasting is no longer its main focus.
Podcastle assumes you will record. With Jellypod you bring source material (a topic, an article, a PDF, slides, or a video) and it generates a finished episode: an editable AI script, AI hosts with their own personalities, voice cloning, a much larger voice library (see the table below for current counts), and a timeline editor for music. It then hosts the show on an RSS feed, publishes a podcast website, and distributes to Spotify, Apple, and YouTube through that feed, with audience analytics.
If you are weighing recording studios specifically, our Jellypod vs Riverside comparison covers that angle.
Podcastle rebranded to Async in early 2026 and now leads with AI video, with podcasting a smaller part of the suite.
Our Verdict: The Best Podcastle Alternative
Async is the better choice if your podcast begins with a microphone. Its remote multitrack recording, transcription, and audio cleanup work well, and at $11.99/mo billed annually for Essentials (with a free plan to try) it is an affordable way to record and edit a conversation-driven show.
Jellypod is the better choice if your podcast begins with a document or a topic and you do not want to record. It generates the episode from your sources, gives you persistent AI hosts, and covers hosting, distribution with a podcast website, and measurement. Educators, healthcare and CME teams, L&D departments, faith leaders, and non-profits use it to turn expert material into a published podcast without a studio.
