A video is the core output of Demomatic. You describe what you want to demonstrate in a prompt, and Demomatic navigates your live application, records the interaction, adds narration, captions, music, and effects, then stores the finished video in your library.

​
Video properties

Each video has the following properties:

​
Generation options

When you generate a video, you can customize how it looks and sounds:
  • Font — typeface for on-screen text ("Inter", "OpenSans", "Playwrite", "Poppins", "Roboto")
  • Voice — AI voice for narration ("ash", "onyx", "nova", "fable")
  • Music — background music track ("observer", "lawrence", "all_i_am", "lust", "denied_access", "75_and_lower")
  • Background — visual background style
  • Captions — whether closed captions are included

​
How video generation works

After you submit a prompt, Demomatic processes it through the following steps:
1

Researching domain context

Demomatic analyzes your domain to understand your application’s structure, pages, and available interactions.
2

Authenticating

Demomatic logs in to your application using the login steps you configured on the domain.
3

Determining actions and recording

The AI determines the browser actions needed to fulfill your prompt, then navigates and records the real application.
4

Analyzing and grouping actions into flows

Recorded interactions are analyzed and grouped into logical flows with titles and captions.
5

Trimming recorded video

The raw recording is trimmed to remove pauses and irrelevant footage.
6

Preparing video segments

The video is split into segments, ready for narration and effects to be applied.
7

Generating narration and adding effects

AI-generated narration is synthesized, and music, captions, B-roll, and text animations are added.
8

Storing video in library

The finished video is stored and made available in your library.

​
Video library

Your videos are organized in a library. You can create folders to group related videos—for example, by use case, audience, or feature area. When you retrieve videos from the API, you can filter by folder.

​
Sharing

Videos can be public or private:
  • Public videos are accessible to anyone with the link—no sign-in required.
  • Private videos require an authenticated session to view.
Toggle the is_public field on a video to control its visibility.

​
Embedding

You can embed any public video on your website or in your product using the embed endpoint:
This returns a self-contained HTML page with a full-screen video player. Drop it into an <iframe> to embed it anywhere.

​
Self-heal

Videos can be configured to automatically regenerate when your application changes, so your demos stay current without manual effort. See Self-Heal for details.
