How to use it

Generate a separate narration track for a video you are editing in CapCut. Paste your script, download the resulting MP3, and add it to your project through CapCut's media or audio import controls.

01

Write the words you want to hear

Remove shot directions and editing notes from the script. Keep the opening concise and divide longer explanations into sections that match your clips.

02

Generate and save the MP3

Choose a voice suited to your script's language, then review the narration. Save the downloaded file somewhere accessible from the device where you edit in CapCut.

03

Import and position the audio

Open your CapCut project and import the audio file using the controls available in your version. Place it on the timeline, align the clips, and balance it with music.

What you can make

  • A narrated vertical product walkthrough
  • An explanation accompanying a craft tutorial
  • A voice over for a short travel montage

Privacy first

Your draft stays in your browser until you generate. Guest audio is not saved to a personal history.

Make the result useful

Make short videos readable and audible

Avoid asking viewers to read dense text while listening to a different explanation. Give the narration room to finish and preview the result on a phone. If background music hides consonants or the final words of sentences, lower it in the editor.

Keep the source audio easy to replace

Store the script and MP3 together with a clear version name. If you revise a sentence, check that the replacement fits the existing clip timing. CapCut's import controls differ between desktop, mobile, and web, so follow the available file import workflow.

Questions about this workflow

Is this a CapCut plugin or integration?
No. This is an independent text-to-speech workflow. You download an MP3 and import it into CapCut yourself.
Why use a separate file if CapCut has voice tools?
A separate MP3 lets you keep narration as a reusable audio asset alongside your script. You can also use CapCut's own available voice features if they suit your edit.
Will the tool change my CapCut project?
No. It generates audio only. Clip editing, caption creation, audio positioning, and video export remain in CapCut.
