Vocnu vs Rask AI
Rask AI dubs videos for creators who publish them in other languages, in a clone of the speaker's voice and, on its higher plans, with lip-sync. Vocnu adds a voice-over and subtitles for people who want to understand a video: in the browser as they watch, or from a file they upload, for a fraction of the price per minute. Here is how they differ.

Side by side
| Feature | Vocnu | Rask AI |
|---|---|---|

| Watch without uploading | Yes: a browser extension voices YouTube, streaming sites and live streams as you watch | No browser extension: it dubs the videos you add to its app |
| Languages | 35 languages to translate into | 135+ languages, voice cloning in 57 |
| The speaker's own voice | No: one voice you choose reads the whole video | Yes, voice cloning from the free trial on |

| Free to try | 40 credits on sign-up: 20 minutes with the voice-over | 3 minutes |

| Longest video | 5 hours | 5 hours |
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 language | 2 credits per minute |
|---|---|
| Already voicedA minute Vocnu plays from a voice-over it already made of the same video in your language and voice | 1 credit per minute |
| Subtitles onlySubtitles in your language over the video | 1 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.
