SignValid: a demo made from its website address

SignValid, like OIData, is made by the same person as ShotDemo, which is why it could be used here with no one else's permission needed.

What ShotDemo did by itself

1. Read the brand from the home page: the name, the green accent colour and the logo.
2. Picked six pages worth showing, ranked by what a visitor would want to see first: the home page, the e-Aadhaar page, a page for Tamil Nadu building plan approvals, the list of trusted certificate authorities, the guides and the about page. It skipped the sign-in, legal and blog links, as it always does.
3. Captured each page twice: at desktop width for the wide video, and at phone width for the tall one, because the site has a real mobile layout.
4. Described every screen in plain words, from the screenshot itself.
5. Wrote the script, one caption and one spoken line per page, with an opening line and a call to action at the end, and chose a camera move for each page: a pan down the long home page, a push toward the upload box on the e-Aadhaar page.

The AI writer is told to use only what the website itself says. It still gets things slightly wrong sometimes, which is why the next step exists.

What a person changed

• Two lines rewritten: the line over the guides page and the line over the about page, so each says only what those pages say.
• Every claim checked against the live site. "Seven generations of India root" matches the site's trust store page, which lists seven root generations. "Checked in memory and never stored" is the site's own description of how it handles files.
• A pronunciation list added so the voice says "CCA" letter by letter and reads signvalid.in as "signvalid dot in", while the captions keep the normal spelling.

The whole check took a few minutes. It is worth doing on any AI-written script: a model can merge two true facts into one false one, and a product video is a public promise.

The phone version

In 9:16, ShotDemo shows the phone captures inside a phone frame and scrolls down each page, instead of squeezing a desktop page into a tall box. The 15-second ad keeps the home page, the e-Aadhaar page and the trust store, with one line across all three.

What the voice says

The full tour, scene by scene: the caption on the screen, then the line the voice reads. The player's captions button shows the same words over the video.
