Async is a browser-based recording studio and AI video editor: you record remote guests, clean up the sound, cut the video and turn it into clips, dubs and subtitles in one place. It has a free plan with small lifetime allowances, and the paid plans run on monthly credits. What decides whether it suits you is how many hours of remote recording and how much AI work you need each month.

What is Async?
Async was called Podcastle. The company is Podcastle Inc., a Delaware company in the United States that now trades as Async, and the old podcastle.ai address leads to async.com. The site is published in English and Spanish.
Async runs in the browser, with Chrome recommended, and comes with a Chrome extension. An iPhone app handles recording and clips, though it does not work on iPads. There is no Windows or Mac desktop app.
Recording and editing with Async
Remote recording brings up to 10 participants into one session and records each person locally, with a backup in the cloud, so every speaker lands on a separate track. Screen share recording is built in. The monthly recording allowance is 2 hours on Essentials, 20 on Pro and 50 on Teams.
Video is edited on a multitrack timeline or by giving the AI chat instructions. The cleanup tools cover filler word and silence removal, Magic Dust to bring any audio up to studio quality, noise reduction and auto leveling. Background Removal takes the background out of a video recording, and Eye contact adjusts your eyes to face the camera even while you read.
Automatic subtitles come on every plan, and paid plans can translate subtitles into more than 70 languages. Transcription covers English, Spanish, German, French and Italian. AI dubbing translates your video into more than 30 languages in your own voice, with options to remove background audio and add lip sync.
For voice work, text to speech offers more than 1,000 AI voices in more than 15 languages, and voice cloning makes a digital copy of your voice that speaks whatever you type. AI Clips finds the strongest moments in a recording and turns them into short clips for TikTok, Reels, Shorts or ads, in the web app and the iPhone app.
Async also generates media from credits. Its video models include Seedance 2.0, Veo 3.1, Kling 3, Wan 2.7 and Grok Imagine, alongside image models, HeyGen avatars and music. A 4-second Seedance 2.0 clip at 720p costs 18 credits. The stock library adds images, video and more than 7,000 royalty-free music and sound effect tracks.
Exports reach 4K on Pro and Teams, Full HD on Essentials and 720p on the free plan. The watermark can be switched off at export on any paid plan.
Working with other people
Async offers team workspaces with reviewer, creator, admin and owner roles. The Teams plan adds a Brand Kit that holds logos, fonts, colors, images and voices, so content matches your brand.
Async's public API is a Voice API covering text to speech, speech to text and voice cloning. It does not create or edit videos.
Async pricing: what each plan gives

Credits are Async's main cost unit. AI tools, media generation, dubbing and chat editing all draw on a monthly credit allowance that resets each cycle.
The Free plan needs no credit card. Its allowances are lifetime totals: 10 AI credits, 1 hour of media in AI chat, 1 hour of remote recording and 1 hour of automatic subtitles. Exports run at 720p with the Async watermark, limited to one export file, with 2 GB of storage.
Essentials costs $19.99 a month, or $11.99 a month billed yearly, with 450 credits a month and Full HD export. Pro costs $39.99 a month, or $23.99 a month billed yearly, with 1,200 credits a month and 4K export. Teams costs $84.99 per creator a month, or $49.99 a month billed yearly, with 3,000 credits a month per creator, 4K export and the Brand Kit. Business is custom priced and aimed at enterprises that need team collaboration and commercial usage.
A 7-day free trial covers every paid plan, but only on yearly billing, and the full year is charged when the trial ends. You own the content you produce.
Privacy and security
Async is SOC 2 certified and GDPR compliant. Data is encrypted at rest and in transit, and the platform runs advanced vulnerability checks.
Support on the free plan is by email. Paid plans add live chat inside the app, Monday to Friday, and Business adds a dedicated Slack channel. There is also a Discord community.
Who Async suits
Async suits podcasters, interviewers and video creators who record remote guests and want to edit, clean up, subtitle and clip the result without leaving the browser. Creators who publish in several languages get dubbing in their own voice, and the credit plans also cover AI video and image generation from several model makers.
It suits less well anyone who wants a desktop app or editing on an iPad, since it runs in the browser and on iPhone. The free plan's lifetime allowances are enough to try it but not to keep working on, the trial is only on yearly billing, and remote recording hours on Essentials are small next to Pro and Teams.
