I run a finance channel in English with 40K subscribers. Every comment section had the same question: '¿Subtítulos en español?' I kept saying 'soon' until I realized 'soon' meant never — manual translation of 90 videos was going to cost me $9,000. A friend in Miami told me about this tool. First test: my 12-minute explainer on index funds, English to Spanish, done in four minutes. The Spanish voice didn't sound like a robot reading a script; it sounded like a presenter. I hired a native speaker to review the subtitles — she fixed two terms. That was it. My Spanish channel hit 15K subscribers in six weeks.

Generates natural-sounding Spanish speech from English audio, using selectable AI voices.
Exports time-aligned Spanish subtitles in SRT format, ready for YouTube upload or editing.
Both dubbed MP4 and SRT files export cleanly—no logos, overlays, or branding added.

Yes—you’ll see the AI-translated Spanish transcript on screen before generating the dubbed video + SRT. You can’t edit the text, but you can cancel and adjust settings if something seems off.
Accuracy depends on clarity of the original English audio and complexity of terms. For technical topics, some phrases may require light human review. The dubbed video + SRT reflects the AI’s best interpretation without manual correction.
Free processing works on most standard YouTube clips. On longer files, the system completes after a short pass—output quality remains consistent, but very long recordings may truncate at the server level.
