Async, formerly known as Podcastle, has launched its first major platform update since rebranding, introducing a fully agentic production workflow that enables creators to produce ready-to-publish audio and video content through natural language chat instructions. The new system automates cutting footage, structuring narratives, generating voiceovers, and enhancing audio/video quality, reducing post-production time for a typical one-hour recording from 20–48 hours to minutes.

Revolutionizing Content Creation with Agentic AI The rapid adoption of generative AI among creators has highlighted inefficiencies in traditional production workflows. While tools assist with specific tasks, much of the effort—reviewing raw footage, selecting moments, editing sequences, and polishing output—remains manual and time-intensive. Async's agentic update transforms this by making natural language the central interface. Creators describe their vision in conversation, and the platform autonomously executes complex production steps, delivering publish-ready results with minimal intervention.
From Editing to Directing “Our mission is to democratize video and audio production. You shouldn’t need a dozen different apps to bring one idea to life. We’re moving past tools and into systems that understand intent,” said Arto Yeritsyan, CEO and Founder of Async. “The manual editing job is disappearing. With this update, we’re making production invisible — connecting creative intent directly to execution. You don’t edit anymore; you direct.”
This shift empowers creators to focus on storytelling and strategy rather than technical execution, streamlining the journey from raw recording to final output.
Opening the Voice Engine via Async Voice API For developers and engineering teams, Async is providing direct access to its proprietary voice production infrastructure through the Async Voice API. The API delivers high-quality, low-latency voice generation at competitive cost, supporting applications such as real-time conversational agents, live streaming enhancements, and interactive audio experiences. By exposing this core technology, Async aims to foster innovation across broader AI-driven audio ecosystems.
Flexible Pricing for Scalable Usage To accommodate the compute-intensive nature of agentic workflows, Async adopts a hybrid model. Standard subscriptions grant access to the production studio, while generative AI features consume credits from monthly allowances or on-demand top-up packs. The Async Voice API follows a separate pay-as-you-go structure, enabling precise cost control for both creators and developers.
Immediate Availability and Future Expansion The agentic production workflow and Async Voice API are live on the Async web platform. Audio content creation is fully operational today, with video production features scheduled for later rollout. New users can start with a one-week free trial to explore the chat-based system.
Async continues to evolve as a comprehensive creative operating system, backed by leading investors and recognized for product excellence. The rebrand and this update mark a significant step toward making high-quality content production accessible, efficient, and intent-driven for creators worldwide.
