Screen recordings and product demos are the fastest way to show how software works. But most of them are silent, and recording a good voiceover takes time, a quiet room and often several takes. SonaVid closes that gap: it turns silent videos into narrated stories with AI.
How it works
- Upload your video. Drag and drop a screen recording, product demo or tutorial (MP4, MOV or WebM).
- The AI writes the script. SonaVid watches the video, identifies every UI transition and action, and writes a narration script that is timed to what happens on screen.
- Download the narrated video. Review and edit the script if you like, then render. The finished video comes with a natural AI voiceover.
What is included
- Narration in 27 languages, including English, German, French, Spanish and Japanese
- Natural AI voices powered by Google Gemini TTS, with pauses and emphasis
- A script editor with timestamps: add, remove and reorder segments
- Fast server-side rendering, no local software needed
- A REST API and an MCP server, so you can drive the whole pipeline from your own code or from Claude, VS Code and Cursor (Pro plan and above)
Who it is for
Product teams who publish feature walkthroughs, consultants who document solutions, trainers who create tutorials, and anyone who needs the same video in several languages.
