Which one to choose

Choose Rask AI if you publish your own videos in other languages and want them to sound like you: it clones the speaker's voice and, from Creator Pro up, matches the lips. That is work Vocnu does not do.

Choose Vocnu if you want to understand videos in your language: to watch YouTube, online courses, streaming sites or live streams with a voice-over as you play them, or to add a voice-over and subtitles to a file. You keep the original sound under the translation, so the speakers' own voices still come through, and a minute costs €0.13 to €0.20.

What you get from a file

Upload a video or audio file to Vocnu, see the price before it starts, and download an MP4 with the voice-over as its main audio and the original sound as a second track, subtitles as SRT, VTT and ASS files, and the voice-over audio. A video with the voice-over costs 2 credits a minute, €0.13 to €0.20.

Watching with the extension

The extension charges by the minute you watch, and a video already in your language costs nothing:

With voice-overThe voice and subtitles in your language2 credits per minute
Already voicedA minute Vocnu plays from a voice-over it already made of the same video in your language and voice1 credit per minute
Subtitles onlySubtitles in your language over the video1 credit per minute
  • With the voice-over, a minute costs €0.13 to €0.20, depending on the credit pack.
  • New accounts get 40 free credits after confirming their email address: 20 minutes with the voice-over or 40 minutes of subtitles.
  • Watching the same minutes again within 30 days, in the same language, voice and mode, is free.

Questions and answers

Is Vocnu a Rask AI alternative?

For watching and understanding videos, yes, and it costs less per minute. For publishing your own channel in other languages in your own voice, with lip-sync, Rask AI does things Vocnu does not.

Does Vocnu clone voices?

No. You choose one of its voices, which reads the translation over the original sound. The original voices stay audible under it.

Can I translate a YouTube video with Vocnu without downloading it?

Yes, with the browser extension for Chrome, Brave and Edge: it voices the video while you watch, for 2 credits a minute.
