Podcasters and video creators who want recording, editing, chat-directed repurposing, and publishing handled in one browser-based tool
Standout Feature

Alternatives
Overview
Podcastle has rebranded to Async, a chat-based AI video creation, editing, and repurposing suite that still includes the original record-podcast and edit-audio workflows rather than dropping them. You can direct edits and content transformations through a chat interface, and the platform continues to support the core podcast recording and cleanup features that made Podcastle popular, alongside newer video-focused tools. Its Magic Dust feature, carried over from Podcastle, automatically removes filler words, levels audio across speakers, and cleans background noise in a single click.
AI voice cloning lets you fix mispronunciations or add lines post-recording without reshooting. Remote recording captures each participant locally at studio quality and syncs tracks automatically.
Our Take
Evaluate whether its workflow fits the edits you actually make, including transcript corrections, audio cleanup, and delivery formats. The former Podcastle name describes the product’s history, not a separate current platform, and the old processing-speed claim should not be treated as a measured promise for today’s product.
- • Magic Dust makes a full hour of audio edit-ready in under a minute
- • No software install: entire workflow runs in the browser
- • Voice cloning for corrections is unique among podcast tools
- • Voice cloning accuracy degrades on complex sentence corrections
- • Export quality on the free tier is capped at lower bitrates
- • Not as powerful as Descript for detailed word-level editing

Trust & Data

- Training on your data
- Not publishedAsync's (formerly Podcastle's) AI terms of use say user input may be processed to improve services and ensure policy compliance, a broad improve-services framing rather than an explicit statement that customer data trains models, and no opt-out mechanism is described; this is treated as not-published/ambiguous rather than a confirmed 'yes'. The privacy policy explicitly covers voice recordings and voice-clone or biometric data, including a right to request deletion of voice clones. A specific retention period could not be confirmed: the retention/destruction schedule section returned no retrievable body text during extraction.
