Turn application code into animated product demo videos.



DemoVexa is a local desktop application that creates narrated, animated product demonstration videos directly from software source code. Instead of capturing actual displays through screen recording tools, the software examines project repositories, documentation, and interface components to generate product walkthroughs. It handles script creation, voiceover synthesis, and interface animations while keeping source code stored locally on your device.
Software teams frequently struggle with maintaining up-to-date video demonstrations. Traditional screen recordings quickly become outdated whenever an interface updates, exposing sensitive test data or requiring manual editing, script adjustments, and fresh voice talent. DemoVexa resolves this maintenance bottleneck by recreating application interfaces using clean sample data and code-level representations that update whenever new code deploys.
What sets DemoVexa apart is its code-aware architecture powered by AI integrations like Claude, Codex, or GitHub Copilot alongside Remotion. It translates components and user flows into customizable React scenes. By working directly with your underlying code and personal API accounts, it renders crisp visuals across multiple aspect ratios without marking up third-party platform costs.
DemoVexa is built for individuals and teams looking to produce technical product videos without manual screen recording:
Software launches benefit from DemoVexa by generating full launch videos across YouTube, X, and LinkedIn from a single project folder, complete with aspect ratios adapted for both mobile feeds and desktop players.
Customer success teams can convert knowledge base tutorials and changelog notices into narrated walkthroughs, teaching complex user workflows step-by-step using dummy data instead of private client records.
Global product releases use DemoVexa to translate interface scripts and sync native voiceovers into dozens of languages, keeping UI terms accurate while timing scene transitions to fit each localized narration track.
