Canviz

AI voiceover

Add an AI voiceover to a video, with captions timed to the voice

For any video that needs a narrator. Bring a script or give Canviz a topic and tone, choose a voice, and the video comes back narrated, captioned and cut to the script's length.

Free on your first video. No credit card required. See it in the demo.

How it works

AI voiceover, step by step

  1. 1

    Add a video

    Paste a YouTube link or upload an MP4, MOV, WebM or MKV, up to 6 minutes. A longer video is trimmed first or switched to Clips.

  2. 2

    Write or generate the script

    Type up to 4,000 characters, or give Canviz a topic and a tone and it writes the script. Tell it what to change in chat and it revises.

  3. 3

    Pick a voice and a mode

    Choose a voice from the list; each one has a preview. Narrate reads the whole script over the video; Hook only reads just the hook line at the start.

  4. 4

    Get the video

    Captions are timed to the voice and a hook title opens the video. Download the MP4 or schedule it to TikTok, YouTube or Instagram.

What you get

What comes out, and what you control

  • Narrate or Hook only

    Narrate has an AI voice read your script over the whole video. Hook only has it read just the hook line at the start.

  • Your script or a drafted one

    Paste up to 4,000 characters of your own, or give a topic and a tone and Canviz writes the script.

  • Voices with previews

    Pick a voice from a list and play a preview of each before you choose.

  • Cut to the script

    The footage is cut to the script's length. A 90-second script over a 6-minute video gives a 90-second video.

  • Captions timed to the voice

    Word-timed captions in 23 styles, placed so they never cover a face. Edit any word or turn them off.

  • Change voice

    Re-voice the speaker with another voice and keep the words the same. Not offered while narrating.
