How is this different from PowerPoint's export to video?
PowerPoint records slides as-is. Lecturn writes natural spoken narration with AI, lets you edit every slide, adds styled captions, and syncs audio precisely to each slide.

Yes — every slide has a full script editor with autosave, per-slide regenerate, and audio preview before you approve the final video.
What languages and voices are supported?
24 language and region options including English, Spanish, French, German, Arabic, Hindi, Chinese, Swahili, Romanian, and Albanian — each with curated Piper TTS voices.
What file formats do I get?
MP4 video at 1080p with optional burned-in captions, plus a separate SRT subtitle file for LMS or YouTube upload.
