How to use it

Add spoken explanations to a product demonstration using a script you control. Generate an MP3 for your screen recording, then align the narration with clicks, transitions, and results in your video editor.

01

Match the script to the interface

Use the exact names of visible buttons and fields. Explain the purpose of an action before describing it, and remove steps that no longer match the product.

02

Check a representative section

Generate narration for a section containing product names or technical terms. Listen carefully and adjust the wording before continuing with the rest of the demo.

03

Align audio with the recording

Download the MP3 and import it into your editor. Leave each important screen visible until its explanation finishes, and remove waiting time that adds no useful context.

What you can make

  • A walkthrough of a first-time setup
  • A narration explaining one software feature
  • A short support video showing a repeated task

Privacy first

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

Make the result useful

Keep narration useful when the screen changes

Prefer named controls to phrases such as 'click here.' If the layout changes later, specific action descriptions are easier to review and update. Record with demonstration data and check for private information before sharing the final video.

Separate stable explanations from changing details

An overview may stay useful longer than a sequence of interface instructions. Save those sections separately so a renamed button only requires a small update. Review the final video against the current product rather than relying on an older script.

Open your project and select the activity tab. You can now review the latest changes in one place. Use the date filter to focus on the period you want to check.

Questions about this workflow

Can this tool see my screen recording?
This text-to-speech workflow uses the text you paste. It does not inspect the recording or generate an explanation from the interface.
Does it time the narration to my clicks?
No. You synchronize the MP3 and recording in your editor. Adjust the script or screen duration when an explanation needs more time.
How should I handle product abbreviations?
Try the abbreviation in a short section, then listen. Spell out the term or revise the phrasing if the pronunciation is unclear.
