The AI perfectly captures terminology.
The AI perfectly captures math terminology and equation explanations. My students say the captions help them follow along better. Even added Spanish subtitles for my ESL students haha.

been creating courses for 3 years and updating content was always a nightmare. now when info changes, i just record the new section and match my original voice with the clone. saved me from re-recording, thanks!

The translation feature is solid.
The translation feature is solid - legal terms stay accurate. Created one harassment prevention course, exported in 8 languages. HR loves the consistency. Rendering gets slow when exporting multiple languages simultaneously, but still faster than hiring translation services.
@brandon_trains

Helped me improve production quality.
Auto-captions catch code syntax perfectly, voice stays consistent across 15 hours of content. Only downside - would love direct Udemy integration. But my course rating went from 4.2 to 4.8 stars after adding professional captions.
