DemoVexa

Why it exists

DemoVexa is an AI-powered desktop application that transforms your software codebase into professional product demo videos. Built for SaaS founders, developers, product marketers, and agencies, DemoVexa analyzes your code and documentation, generates demo scripts, creates animated UI walkthroughs, and adds natural AI voiceovers. Unlike traditional screen recording tools, DemoVexa generates code-driven animations, helping teams create polished, consistent product demonstrations without manually recording every interaction. When your product UI changes, you can update your demos through code instead of starting the entire recording process again. With support for multiple video formats, including 16:9, 9:16, and 1:1, DemoVexa helps you create product launch videos, feature announcements, onboarding tutorials, social media content, and marketing demos. Its desktop-first workflow keeps your source code on your computer while you create videos using your configured AI tools.
