Hook + Demo video maker
Pair a short attention clip with your product screen recording, then tune the copy, timing, and handoff in one vertical video workflow.
Two-part story
Hook earns attention. Demo proves it.
Three reaction hooks
A strong Hook + Demo opening feels like a real reaction to something the creator just discovered. It makes the next shot necessary, then lets the demo or receipt close the loop.
Generate a hook from your demo
Curiosity reaction
Since when do we have to do pushups to get on Instagram? 😩
The reaction makes the new rule sound unbelievable and leaves one obvious question: is that real? The screen recording answers it immediately.
No-way discovery
No way I found out my brother has to do pushups to scroll...
“No way” gives the clip a real reaction while the brother detail makes it feel overheard rather than written like an ad. The demo reveals what she found.
Relationship reveal
No way my boyfriend is this clingy...
The relationship detail raises the stakes without explaining the moment. Her phone-first reaction hands the story directly to the message reveal.
The editor
Select the opening clip, bring in one focused screen recording, then refine the overlay and transition instead of rebuilding a timeline from scratch.

It is a vertical video with two clear parts: a short opening clip and message that earn attention, followed by a product screen recording that demonstrates the promised action.
The Media Library accepts MP4 product recordings up to 60 seconds and 100 MB. Portrait recordings work best for the 9:16 canvas.
You can choose the hook clip, select or upload the demo, rewrite and reposition text, change the viral text style, alignment, size and outline, trim clips, set a 0.5 to 3 second hook duration, and adjust or swap audio.
Viraal can render a Hook + Demo MP4 in recent Chrome and Edge using browser WebCodecs when the selected media is ready and compatible. Safari and Firefox export are not supported, and a recording that is still processing must finish before export.
The browser export path has a soft composition cap of about 64 seconds. Keeping the hook short and the product recording focused also makes the handoff easier to understand.
