Why product demos need care
Choose one integration task, such as authenticating or making a first request. Supply the relevant API guide and a local code folder when available, then review generated terminology, sample payloads and screens. Never include real secrets or customer data in examples.
How DemoVexa makes a video
Connect a product workspace with its code, website or documents. Start a project with a one-line idea and review the generated brief. Edit the script and on-screen captions, choose an AI voice, your own recording or captions with music, then review the planned scenes.
Approve the scene plan to build an animated preview. Check the screens, labels and timing, ask for changes if needed, then render the formats and languages available on your plan. Export and publish the files yourself.
- The product UI is recreated from the workspace context; it is not a captured customer session.
- DemoVexa does not automatically refresh an existing video when code changes.
- Review product claims, sample data, captions and the final preview before sharing.
What to provide
A fictional developer portal could demonstrate creating a test key, sending a sample request and reading its response. Use placeholder credentials and confirm each statement against the current API docs.
Add a local code folder or a reachable website, relevant how-to guides or product documents, and a clear idea of the viewer and task. Select the platform and length in the project brief. If you use a repository, clone it locally and pull the version you want to show first.
What you can export
Export an MP4 in Landscape 16:9, Reel 9:16 or Square 1:1, depending on your plan. A project can also provide on-screen captions, timed SRT or WebVTT subtitles, cover images and draft post copy. Each format and language is rendered separately.
Example workflow
A fictional developer portal could demonstrate creating a test key, sending a sample request and reading its response. Use placeholder credentials and confirm each statement against the current API docs.
Treat this as a sample scenario, not a customer case study or a published DemoVexa video. Use synthetic data and verify the behavior against your own product before release.
Plan your next step
Choose the video type that fits the story, check which formats and languages your plan includes, and leave time to review the finished preview before publishing.
Frequently asked questions
Can DemoVexa make an API demo video?
It can help create an explanatory video from local product code and documentation. Provide one focused task and review the technical steps and any sample values carefully.
Can I show a real API key or customer request?
No. Use placeholder credentials and synthetic data. Do not include API keys, personal information or customer payloads in your brief, scripts or scenes.
Does DemoVexa run API calls or test my SDK?
The documented workflow reads code and product docs to plan and build a video. It is not an API test runner and does not verify that an endpoint or SDK call works.
