Async (formerly Podcastle)

Async is what Podcastle became: the company behind the browser-based podcast studio has renamed itself and moved podcastle.ai to async.com, widening the product from podcasts to video in general. The recording side is still the core for shows. Its remote studio records every participant locally on their own device as a separate audio and video track, up to 4K video and 48 kHz audio on paid plans, and uploads in the background so a shaky connection does not ruin the master. Hosts get a branded waiting room, a teleprompter, producer mode, screen-share recording and sessions of up to ten participants, and each recording arrives with a full transcript.

Editing happens in a multitrack timeline or by chatting with the AI editor: ask it to remove filler, pauses and bad takes, cut to the beat of a music track, add synced captions, or find the strongest moments and turn them into vertical clips for TikTok, Reels and Shorts. Magic Dust and the AI noise reducer clean speech recorded in poor rooms, silence removal tightens a conversation in one click, and eye-contact correction fixes presenters who read from a script. Generative tools sit in the same project — text-to-speech and voice cloning for narration, B-roll, music, sound effects and image generation from third-party models — along with AI dubbing, lip-sync and thumbnails. Finished episodes can be hosted and published to the major podcast directories from inside the app, and an iOS app covers recording, clips and the teleprompter on the phone.

Pricing is a free plan plus Essentials, Pro and Teams subscriptions and a custom Business tier. The free plan includes one lifetime hour of remote multitrack recording, recording at up to 720p and 44 kHz, 10 lifetime AI credits and 2 GB of storage. Paid plans raise recording to 2, 20 or 50 hours a month, add monthly AI credits (450, 1,200 or 3,000 per user), 4K and 48 kHz on Pro and Teams, watermark removal and up to 1 TB of storage, with team workspaces on the higher tiers.
