You record remote interviews, clean audio in one click with Magic Dust, generate narration from a library of 1000+ AI voices across 15 languages, and clone your own voice with Revoice on Pro plans. Recent additions include AI dubbing, subtitle generation, and a viral clip generator for TikTok, Reels, and Shorts.

Frequently Asked Questions

What is Podcastle?

Podcastle is an AI-powered audio and video creation platform for podcasters and creators, covering recording, editing, transcription, and AI voices. As of early 2026 it rebranded to Async, and podcastle.ai now redirects to async.com, though the underlying recording and editing tools remain the same.

Is Podcastle free?

Yes, the platform, now Async, keeps a free tier so you can record and edit at a basic level. Paid plans start around 12 dollars a month and scale up toward roughly 40 dollars a month for heavier creators, with annual billing saving about two months compared to paying monthly.

What is Podcastle best for?

Podcastle, now Async, is best for solo podcasters and creators who want recording, AI cleanup, and editing in one browser tool without a studio. It handles remote interviews, noise and silence removal, transcription, AI clips, dubbing, and subtitles, making it strong for repurposing one recording into many formats.

Is Podcastle the same as Async now?

Yes. Podcastle officially rebranded to Async in January 2026 to reflect its move beyond podcasts into video and developer-facing AI voice tools. Existing accounts, projects, and pricing carried over unchanged, and the old podcastle.ai address now redirects to async.com where the expanded platform lives.
