About
Async (formerly Podcastle) is an AI-powered audio and video creation platform that enables creators, businesses, and developers to record, edit, dub, subtitle, generate clips, clone voices, and build voice agents. Originally founded in 2020 as Podcastle—a Chrome extension that converted articles into podcasts—the platform evolved into a full creative suite and rebranded as Async in early 2026. The platform offers an AI creative suite spanning video generation, image generation, text-to-speech, a recording studio, video editor, audio editor, AI transcription, voice cloning, translation and dubbing, and an open voice API for developers. Async is backed by AI Fund (Andrew Ng's firm) and targets both individual creators and enterprise teams including marketing, internal communications, and learning & development use cases.
