Ultra-Realistic AI Voices
20+ neural voices that sound like a professional narrator — no robotic monotone, no recording booth, no retakes.
20+ Languages, Auto-Detected
Write speaker notes in any supported language and the right voice and pronunciation are selected automatically — or mix languages across slides.
Script = Speaker Notes
The narration reads exactly what you write in each slide’s notes. Edit the script in the built-in editor until it’s right.
Composed Automatically
Slide timing follows the narration length per slide. Out comes a clean 1080p MP4 — no timeline editing, no video software.
Publish Anywhere
The MP4 works everywhere video does: course platforms, YouTube, intranets, sales follow-ups, social posts.
Course Content at Scale
Turn an existing deck library into video lessons in an afternoon — ideal for trainings, onboarding, and e-learning.
