Frequently Asked Questions
Everything you need to know about Saulvo and AI video lessons.
What is Saulvo?
Saulvo is an AI-powered educational video platform that turns concepts, code snippets, and PDF documents into animated, narrated video lessons. Powered by Remotion and Gemini 2.5 Flash, Saulvo automatically plans the curriculum, designs custom SVG diagrams, synchronizes voice narration, and renders crisp 720p/1080p videos.
How does Saulvo turn code into an animated video?
When you paste source code into Saulvo, our pipeline parses your logic and structures it into progressive explanation scenes. It syntax-highlights each line and animates code execution step-by-step alongside synchronized spoken audio explanations.
How is Saulvo different from avatar video tools like HeyGen or Synthesia?
Avatar tools focus on synthetic humans talking in front of generic slides. Saulvo is engineered specifically for deep technical and STEM understanding—animating actual data structures, code syntax, mathematical equations, and dynamic system architecture diagrams.
Can I upload PDFs, research papers, or lecture notes?
Yes. You can upload PDFs or documents directly into the composer. Saulvo extracts the key concepts, formulas, and structural takeaways, transforming dense documents into engaging, animated 5-minute video explainers.
What voice accents and languages are supported?
Saulvo provides high-fidelity AI narration with word-level caption alignment across multiple English accents, including US, UK, and Indian English, automatically optimized based on your region or preference.
Can I download the videos as MP4 files?
Yes. You can watch any lesson in the real-time web player with instant seeking, or render and download full MP4 files in 720p or 1080p resolution.
Is Saulvo free to use?
Yes. Saulvo offers a free tier allowing anyone to generate video lessons and explore interactive playback. Paid tiers (Learn, Pro, and Studio) unlock more video minutes, multi-chapter course planning, and MP4 downloads in 720p or 1080p; Studio adds priority generation.
