Async (Podcastle) offers one of the most complete browser-based podcast recording and editing experiences available. The Revoice voice cloning for text-based corrections is a genuine time-saver and multi-guest remote recording quality is strong. At $11.99/month for the Solo plan, it competes well with more expensive professional podcast tools.
Users who need advanced audio engineering controls or complex multi-track mixing will find the feature set limiting compared to dedicated DAWs. The video editing capabilities are basic compared to tools like Descript. For podcasters prioritising simplicity, AI-assisted editing and clean recordings over advanced production control, Async is a strong and cost-effective choice.

Podcastle became my complete podcasting solution. Studio-quality audio from my browser, automatic filler word removal and the Revoice feature means I can fix mistakes just by typing. I have not touched audio editing software since switching.
Really strong AI features for podcast production. The automatic noise removal is reliable and the filler word detection is better than I expected. Multi-guest remote recording works well even at different internet speeds.
Podcastle replaced my entire podcast hardware setup. I cancelled my expensive audio interface subscription and now record studio-quality audio directly in the browser. The AI filler word removal handles my nervous ums perfectly.
