How to use it
Turn your own YouTube script into an audio track for a tutorial, explainer, or narrated video. Generate the voice over here, then combine the downloaded MP3 with footage in your usual editor.
Prepare the spoken script
Write the words viewers should hear. Remove camera directions, timestamps, and editing notes, and separate the introduction from the main explanation.
Listen before editing
Select a voice and generate a short section. Check names, numbers, and the opening sentence; revise awkward wording before generating the next part.
Build the video around the audio
Import the MP3 into your editing timeline. Match footage to each point, adjust background music levels, and watch the complete sequence before exporting.
What you can make
- Narration for a screen-recorded tutorial
- A spoken introduction to an educational explainer
- Commentary accompanying original travel footage

Privacy first
Your draft stays in your browser until you generate. Guest audio is not saved to a personal history.
Make the result useful
Give each sentence a visual purpose
A sentence that introduces a new idea needs enough screen time for its supporting image or demonstration. If the audio feels rushed, shorten the script or extend the relevant shot in your editor. Avoid packing several instructions into one breath.
Keep production notes outside the script
Save source references and shot directions separately from the text sent for narration. Use recognizable filenames for each section so you can replace a correction without losing track of the final edit. Check the finished mix on headphones and speakers.
