Podcastle

Podcastle is an AI-assisted platform for recording, editing, transcribing, and publishing audio and video content. The company announced its rebrand to Async in January 2026, while existing Podcastle accounts, projects, pricing tiers, and billing structures remained unchanged.

The product serves individual creators, marketing teams, communications departments, educators, and developers. Its creator tools run primarily in the browser, while its iOS app supports recording and remote interviews. Developers can use Async Voice API for real-time text-to-speech and speech-to-text applications.

Podcastle provides a browser-based recording studio for solo sessions and remote interviews. Users can record audio and video, work with separate participant tracks, and continue production in the same workspace.

Editing features include multitrack audio and video editing, transcript-based editing, silence removal, filler-word detection, background-noise reduction, and the Magic Dust audio enhancement tool. The platform also supports transcription and export for repurposing content.

AI voice tools include text-to-speech, voice cloning, multi-speaker narration, pronunciation controls, adjustable pauses, and voices organized by language, accent, and style. The current Async voice platform advertises more than 1,000 voices and support for 15 languages.

Async Voice API provides HTTP, streaming, timestamped, and WebSocket text-to-speech endpoints. It also supports speech-to-text, voice cloning, real-time streaming, and integrations with Pipecat, LiveKit, Twilio, n8n, and Picsart Flow.

The official pricing page lists a Free plan at $0 per month. It also lists Essentials, Pro, Teams, and Business plans, but the public page currently does not expose stable dollar prices for the paid creator tiers.

The Free plan includes limited lifetime allowances. The official pricing table lists one lifetime hour for AI-chat media uploads and 10 lifetime AI credits.

Async Voice API includes a free tier without a credit card. Official API information lists 10 free minutes and paid usage starting at $0.50 per hour. API billing is usage-based rather than subscription-based.

Annual creator subscriptions are advertised with savings of up to 40 percent on the official pricing page. Plan limits and included credits can change, so buyers should verify current terms before subscribing.
