What is Async AI
Async (formerly Podcastle) is an all-in-one AI platform for solo creators, businesses, and developers that enables studio-quality audio and video creation without the need for a physical studio. Its suite of AI-powered tools covers recording, editing, transcription, dubbing, subtitling, voice cloning, and one-click content repurposing — all within a single, prompt-driven workflow. The platform combines 100+ advanced AI generative models to make high-quality content creation faster and more accessible.
Key capabilities include ‘Magic Dust’ for automatic noise removal and audio enhancement, AI Clips for turning recordings into short-form social content, AI Dubbing in 30+ languages with lip-sync, and ‘Async Intelligence’ — an engagement-scoring system that analyzes recordings and applies one-click fixes to optimize watch-through rates. Multi-track recording captures separate audio and video tracks per guest locally, ensuring quality is not affected by internet instability.
Originally founded in 2020 as Podcastle, the platform rebranded to Async in early 2026 to reflect its expanded scope, which now includes a developer-facing Voice API (powered by the proprietary asyncFlow v1.0 model) for building voice agents and conversational AI applications. The company has raised $23.5M in total funding, backed by investors including Andrew Ng’s AI Fund, Mosaic Ventures, and RTP Global.

What makes Async AI unique
Async differentiates itself from alternatives like Descript and Riverside.fm by combining a creator-facing AI studio with a developer-facing Voice API (asyncFlow v1.0) on a single platform — meaning the same low-latency, human-like voice models used for podcast production can also be integrated into third-party apps and voice agents. Its 'Async Intelligence' feature, which automatically scores content engagement and applies one-click fixes without requiring manual prompt crafting, is a distinctive capability not commonly found in competitors like Murf AI or ElevenLabs, which focus primarily on TTS rather than end-to-end production.
