How we make money

The tools are free and will stay free. To pay for the time it takes to build and maintain them we use the following, and this page lists all of it.

1. Ads

Some pages may show Google AdSense ads in fixed spots, never on top of the tool or inside your results. Advertising cookies are only used if you accept them in the consent message. See the privacy policy.

2. Affiliate links

When you finish (for example, after downloading your captioned video or your transcript) we may suggest a service for the next step: dubbing, music, a human-reviewed transcript… If you sign up through that link, the company may pay us a commission at no extra cost to you.

  • They are always labelled “Affiliate link”.
  • They only appear on the results screen, never before you use the tool.
  • They do not change how the tool works.

3. Optional one-time Pro version

We are preparing a one-time Pro purchase for people who use the tools every day: custom fonts, a saved brand kit, extra styles, 4K export, batch processing and Word export. Everything that is free today stays free and watermark-free.

4. “Made with Herramientas Libres”

Exported videos include, unless you remove it, a small “Made with Herramientas Libres” credit in a corner. It is a free way to help us. You can always turn it off with a checkbox, without paying.

What we don't do

  • We don't upload your audio, video or files to any server.
  • We don't sell or share personal data. We don't have any.
  • Nobody pays to rank higher in any list.
