Async

Async is an AI video and podcast editor (the platform formerly known as Podcastle) that edits recordings from plain-language chat instructions, built for creators, podcasters and marketing teams who publish often. Instead of cutting by hand on a timeline, you describe the edit you want and the assistant applies it to your footage.

What is Async used for?

It gets you from raw recording to a publish-ready video in fewer steps. The chat-based editor removes filler words, pauses and retakes, syncs cuts to the beat of the music and adds captions. Magic Dust cleans up voices, reduces background noise and trims silences. From the same chat you can generate supporting assets such as B-roll, music or voiceovers using third-party video and image models, and turn a long episode into vertical clips for TikTok, Reels or Shorts.

How does Async work?

Upload a file or record in the browser-based remote recording studio, which captures 4K video and uncompressed WAV audio on a separate track per speaker and uploads to the cloud while you record. Then ask for changes in natural language, review the result and export. You can save your editing style as a reusable Skill, apply templates and a brand kit, and use AI dubbing with lip sync in 30+ languages while keeping your cloned voice.

Who is Async for?

• Podcasters who interview remote guests and want to edit without technical skills.
• Creators and marketing teams who repurpose long videos into short social clips.
• Brands that want to take their content into other languages with dubbing and captions.

Async pros and cons

• Pro: recording, editing, audio cleanup, asset generation and dubbing live in one platform.
• Pro: chat-based editing cuts most of the manual timeline work.
• Con: AI features consume credits, so usage needs watching on long projects.
• Con: after the rebrand from Podcastle, some docs and reviews still use the old name.
