Past your allowance
The vendor sells one-time Top-Up Packs on top of each plan and shows a Top-up packs row, but it publishes no pack size or pack price anywhere on the pricing page.

Commercial use
The vendor states outright that generated audio may be used commercially, naming YouTube monetization, podcast ads and corporate training, and names no plan floor for that right.
Yes! When you use Async for your business, you retain ownership of the output. This means you can use your generated audio for YouTube monetization,…

Consent of the voice’s owner
The vendor places the duty on the user, barring impersonation deepfakes without consent and telling dubbing users to clone only voices they may use, but documents no proof or verification step before a clone is made.

Video dubbing
You upload a video or paste a YouTube link, pick a target language, and the tool clones the speaker's voice, translates and syncs the new track across 30+ languages.
Auto-translate your message, preserve your voice and tone, and deliver perfectly lip-synced dubs across 30+ languages.
Lip sync
Lip sync is an option you switch on in the dubbing settings, matching mouth movement and timing to the dubbed track rather than overlaying it.
AI matches timing and mouth movement so the dubbed voice lines up naturally with the original speaker.
How long a video you can dub
Dubbing bills one credit per minute of video and the plan table caps it at 300 minutes a month on the Teams plan; no maximum file length or file size per dub is published.
AI Dubbing & Lipsync 1 credit / 1 min 300 min (5 hours) Custom

Captions and subtitles
Captions are generated automatically, styled, translated into many more languages, and can be exported as a separate caption file as well as burned into the video.
Once you are happy with your video and the captions, simply export the final video or export the captions in a separate file.
async.com/ai-subtitlesChecked
Voice to video
Generated speech lands in the same browser multitrack timeline as the footage, so voice-over, captions and cuts are placed against the picture in one project.
This online video editor brings recording, editing, captions, audio cleanup, and publishing into one browser-based workspace
Team seats
The Teams plan is priced per creator at EUR 84.99 a month; Viewer roles are free and unlimited, while Creator and Admin roles each need their own subscription.
Viewer roles are unlimited, but the others will require additional subscriptions.

Who owns the audio
The terms say you keep ownership of both input and output and may use the output for any lawful purpose, with no clause ending that right on cancelation, though Async keeps a perpetual license of its own.
As between you and Async, you retain ownership of your Input and the resulting Output, in each case to the fullest extent permitted by law.

Free plan or trial

No credit card is required to sign up for an Async account with the Free plan.
