About
Every release deserves a great demo.
Software teams ship every week. Product videos still take weeks of scripting, recording, voice work and editing, so most features launch without one. DemoVexa closes that gap.
DemoVexa turns code into demos. It reads your product the way a new engineer would, writes a script the way a product marketer would, and builds the video the way a motion designer would, then renders every format you need to publish.
We build on the best tools for each job: Claude by Anthropic for understanding code and writing, ElevenLabs for voices that sound native in 31 languages, and Remotion for frame-perfect video made of React components.
Your product, not stock footage
Videos should show the real screens, names and flows of what you built, so we recreate them from your code.
Local-first by default
Your code is your company. DemoVexa runs on your computer and talks to the AI through your own accounts.
Honest costs
You pay us for the app and pay the AI providers what they charge. No credits, no mark-up.
Show the work
Every step, from brief and script to voice and build, is visible and editable. Nothing is a black box.
Your next release deserves a video.
