Why DemoVexa
Your product, explained. Everywhere people look.
Short product videos help people learn your product, get you found in search and AI answers, and sell it. DemoVexa makes them from your app's code, so they're quick to make and never go out of date.
Getting found
Search, YouTube and AI answers
Every video comes with the text search engines and AI assistants read: a blog post, titles and descriptions, and subtitles.
YouTube is a search engine
People search “how to … in [product]”. A how-to video for each feature puts you in those results, with a title, description and tags written for search.
Video results on Google
Pages with an embedded video can show its thumbnail in search results. DemoVexa writes the blog post the video sits in, with SEO title, meta description and keywords.
Cited by AI assistants
ChatGPT, Perplexity, Gemini and Claude answer from pages that explain clearly. A blog post and subtitles give them the exact steps, in your words.
Subtitles that get indexed
Upload the SRT or VTT file with the video: YouTube and LinkedIn index captions, and they make the video accessible too.
Rank in every language
A native voiceover and translated script in 31 languages lets you reach people searching in their own language, not just English.
Reach on social
Native video for LinkedIn, X, Instagram and YouTube Shorts, in the right format for each, with posts written for each platform.
Growth
Launch, sell and explain
The same video works across the whole funnel: from the launch post to the sales follow-up.
A video for every release
Ship a feature, then make its launch video the same day from the code you just merged, with posts, a blog post and covers.
Sales without a live demo
Send a short demo of exactly what the prospect asked about. No scheduling, no live demo going wrong.
A website that shows, not tells
Replace static screenshots with videos of the real product on your home page, pricing and feature pages.
Content for marketing, ready to share
The marketing kit hands your team the videos, covers, posts and blog post as Word files, or emails them to anyone.
Investors and partners
Show what you've built in a monthly update or a partner pitch, with a video that explains it the same way every time.
Release notes people watch
Turn each release note into a short video, so customers actually see what changed instead of skimming past it.
Why from code
Why DemoVexa makes them from your code
Screen recordings go stale with every release and take hours to redo. Videos built from the code don't.
Always matches the latest app
When the app changes, rebuild the video from the new code or ask Claude to change a scene. No re-recording, no re-editing.
No customer data on screen
Screens are recreated with clean sample data, so there's nothing to blur and no test accounts or notifications in shot.
On brand, every time
Your logo, colours, fonts and call to action in every video, set once per product.
Crisp in every format
One build renders 16:9, 9:16 and 1:1, sharp at any size, with a cursor that clicks on the word that names each action.
Minutes, not days
No recording sessions, no timeline editing, no video team. Write a line, approve the script, and Claude builds it.
Accessible by default
Captions on screen, subtitle files and a script with timings, for people who watch without sound or use a screen reader.
