Pros

Covers the whole podcast pipeline — record, edit, enhance, publish — for less than Descript
Free plan with no card lets you test the full workflow
Asyncflow TTS and quick voice cloning are strong for the price
Low-latency developer Voice API exposes the same voices to apps and agents

Cons

The 2026 rebrand widened the focus — credits now stretch across video and image generation, not just podcasting
AI subtitles are English-only below the Teams plan
No Android app — mobile recording is iOS-only
3.5 Trustpilot score, with complaints about billing and feature churn

Our verdict

Best for: Podcasters who want one affordable browser studio for recording, cleanup, and publishing instead of stitching together a toolchain.

Skip if: Your show is a video-first production edited by transcript — Descript's text-based editor is still stronger for that.

Our review

Async — Podcastle until its January 2026 rebrand — remains the easiest way to run a podcast end-to-end in a browser. Remote recording drops each guest onto a separate lossless track, Magic Dust makes bad rooms sound respectable in one click, and the Asyncflow TTS model's 1,000+ voices with fast cloning handle narration and flub fixes. Where Descript asks $16/month (billed annually) to start, Essentials at $11.99/month undercuts it while including recording that Descript treats as an afterthought.

The rebrand cuts both ways. Bundling Kling and Veo video generation, image models, and a developer voice API into one subscription makes Async remarkable value on paper — but the shared credit pool means a heavy TTS month competes with video experiments, and podcasters who loved the focused tool now navigate a much broader product. The 3.5 Trustpilot score (against a 4.7 on G2) tracks the usual creator-tool complaints: credits, billing, and features moving between plans.

Gaps worth knowing: subtitles are English-only until the Teams tier, there's no Android app, and the editor — while capable — doesn't match Descript's transcript-first editing for video-heavy shows.

Verdict: the best all-in-one studio for audio-first podcasters on a budget, and the strongest free plan in its niche. Video-first shows edited by transcript should still pay up for Descript; developers eyeing the voice API should compare ElevenLabs first.

Frequently asked questions

What is Async, and what happened to Podcastle?

Async is the new name for Podcastle as of January 2026. Same company and accounts, broader product: the podcast studio now sits alongside AI video/image generation, 1,000+ TTS voices, and a developer voice API under one subscription.

How much does Async cost?

There's a free plan with basic recording and no card required. Essentials is $19.99/month ($11.99/month billed annually), Pro is $39.99/month ($23.99/month billed annually), Teams is $84.99/month per creator ($49.99/month billed annually), and Business is custom-priced.

Does Async have an API?

Yes — the Async Voice API offers streaming text-to-speech at roughly 300ms latency plus voice cloning, aimed at developers building voice agents and audio features.

Async or Descript for podcast editing?

Descript's transcript-based editor is still the stronger pure editor, especially for video podcasts. Async wins on price and breadth — recording, enhancement, TTS, and publishing live in one browser app, with a cheaper annual entry point ($11.99/month vs Descript's $16/month).

Can I record with remote guests for free?

Yes, within the free plan's limits — enough to trial a real remote session with separate tracks per guest, though serious use needs a paid plan's recording hours.
