Hook testing
Three hooks for one product before you render any.
Ad Script Generator: Free Hooks and Spoken Lines
Reviral's ad script generator writes a free storyboard from your product photos and facts: a hook, then one spoken line and one camera note per scene of a 15-second ad. Writing and rewriting the script costs nothing; rendering it as a video costs 278 credits (~$3.47) at 720p.

- Free script: hook plus a line per scene
- Every line editable before any render
- Script studio: 15 to 120 seconds, 3 versions
- Turn the script into a 15-second video ad
What the script looks like
In the UGC studio press Write my ad. Each storyboard card has two parts: What you see, the shot, for example the creator holds the bottle up to the window, and What they say, the exact words. The creator speaks each line word for word, so the script you approve is the script in the video.
Change the hook, the format (review, unboxing, tutorial, problem-and-solution, TV spot) or the setting and the old storyboard must be rewritten before Render unlocks, so an outdated script never renders.
Longer scripts: the Script studio
For a script that is not tied to one 15-second ad, the Script studio writes three versions from a few sentences or a link, at a target length from 15 to 120 seconds, in one of 13 styles such as Business, How To or Listicle. A live word meter shows the budget: about 47 words for 15 seconds, 99 for 30 and 216 for 60. Writing scripts there is free too.
What it costs
Scripts are free in both places. A finished 15-second video ad from the script costs 278 credits (~$3.47) at 720p, shown on the Render button first.
Sign-up gives 100 free credits with no card, and the exact charge shows before anything renders.

Frequently asked questions
- Is there a free ad script generator?
- Yes. Reviral's UGC studio writes the ad's hook and spoken lines for free, and the Script studio writes three free script versions from 15 to 120 seconds. You pay only if you render a video, 278 credits (~$3.47) for 15 seconds at 720p.
- Can it write a radio ad script?
- It writes spoken scripts sized by length, which you can trim for radio. American Public Media times radio spots at 2.5 words per second, about 75 words for 30 seconds and 150 for 60, while the Script studio's video word meter aims higher, about 99 words for 30 seconds. Reviral makes the video, not the radio audio, so record the read yourself.
- How long should a video ad script be?
- Write to the length of the ad: the Script studio's word meter targets about 47 words for a 15-second spot. In the UGC studio each 15-second ad has one spoken line per scene.
