Make a product demo video without opening an editor
A software founder had agents record, edit and script an 81-second product demo, and build a fake store with 25 campaigns checked by 932 automatic checks.

What they did
The founder of Sembot, an ad software company, had an agent record his product's dashboard in a browser and edit the video. He gave feedback on each cut. Two models designed a fictional outdoor store with 25 ad campaigns as demo data. A developer agent added it to the product, and the script was rewritten for the new data.
How it went
He says the first cut had no intro and jarring camera jumps. The second added an intro, smooth fades and a slow zoom. The final version runs 81 seconds, and he says his main contribution was complaining.
Worth knowing
His biggest note was not about editing: an empty dashboard makes a weak demo. A separate checker ran 932 automatic checks so the numbers on screen agree.
Try it yourself
Help me make a short demo video of [product name] for [audience]. First, review the product in the browser and propose realistic demo data that shows [the problem it solves], with checks that all numbers agree. Then draft a script under [length] seconds with an intro and a clear finale. Show me the data and script for approval. After that, record the screen, edit with smooth transitions, and add narration in [my voice file or chosen voice]. Share each cut for feedback before finalizing.
Swap the highlighted [parts] for your own details.
