Async (Podcastle)

Async is a web-based creative studio for audio and video that was previously known as Podcastle. It started as a podcast recording and editing tool and now centers on a chat-based AI suite in which users describe the edit they want and the assistant carries it out.

The assistant can fix a rough cut by removing filler words, pauses, repeats and bad takes, sync edits to a music track, clean noisy audio, generate B-roll, voice or music, add and style captions, and find moments to turn into short clips for TikTok, Reels, Shorts or ads. Templates are provided for creators and small businesses, and formats range from podcasts and interviews to vlogs and explainers.

Async is a hosted commercial service with plans on its pricing page, and edits should be reviewed because the vendor notes that AI can make mistakes. It suits creators and small teams who want to produce finished videos without a dedicated editor.
