AI ad script generator

A UGC ad script generator that makes the ad too.

The RiffAds UGC ad script generator is an AI writer you add to a workflow. Give it a brief and up to 4 images, and it writes hooks and a script that go straight to a lip-synced AI actor.

The short answer

What is a UGC script?

A UGC script is the spoken words of a user generated content style video ad: the hook, the problem, the product, the proof and the call to action. An ad script generator writes it from your brief. In RiffAds the script goes to a lip-synced AI actor in the same workflow, and the whole run is priced before it starts.

Best for

  • Media buyers testing hooks
  • Ecommerce and DTC brands
  • Affiliate marketers
  • Agencies with many clients
  • AI agents that make ads

How it works

  1. 01

    Write the brief

    Add an AI writer to a workflow and paste your product facts as text (the writer does not open links), plus up to 4 images such as a packshot or an ad you like.

  2. 02

    Set model and length

    Pick Fast, Balanced or Smart and a character limit. The output is cut at that limit, so set it to fit the actor that will say the script.

  3. 03

    Wire in an actor

    Connect the script to a talking actor, choose the actor and the voice, and the words come back as a lip-synced video.

  4. 04

    Price it, then run

    The workflow shows an up-to price for the whole run before it starts, and you download the finished ad when it is done.

  • 6

    credits for one script from the AI writer, whichever writing model you pick. 1 credit is $0.01.

06FAQ

UGC ad script generator, answered.

Still unsure? Book a call

Open with a hook that names a problem or a payoff, show the problem, bring in the product, give proof you can back up and end with one clear call to action. Write it the way people talk, in short lines and plain words. In a RiffAds workflow the AI writer drafts this from your brief and any product images, then hands the script to a talking actor.

UGC hooks are the opening lines or shots of a creator style ad that make someone stop scrolling. TikTok's ads help center says to introduce your content proposition in the first 3 seconds and to prioritize the hook in the first 6. So lead with the problem or the result, not a logo or a greeting, and ask the AI writer in a workflow for several opening lines on the same brief.

Short enough for the actor that will say it. OmniHuman 1.5 takes under 60 seconds of audio, Seedance 2.5 Actor speaks for 4 to 30 seconds and MiniMax H3 Max Lip Sync takes 5 to under 14.8 seconds. RiffAds estimates 14 characters a second, so a 30 second script is about 420 characters. Audio past an actor's limit is refused, never cut short, but the AI writer does cut its own text at the character limit you set.

There is no fixed number, but TikTok suggests 3 to 5 different creatives per ad group, and a new hook on the same script body is a simple way to get there. Ask the AI writer for several hooks, render each one as its own talking actor ad and let the results decide. No script is a sure winner before it runs.

One script from the AI writer costs 6 credits, whichever writing model you pick. 1 credit is $0.01. Turning the script into a video is priced before it runs: a 30 second talking actor ad is about 848 credits, voice included. The entry plan is $49 a month, and unused credits carry over with no end date.

Not as its own experience. An AI actor has never used your product, and the FTC's consumer reviews and testimonials rule bans testimonials that misrepresent that the speaker exists or used it. Courts can fine knowing violations. The actor can read a real customer's review, with permission and without changing its meaning, if the ad clearly discloses that the person on screen is not an actual customer.

Yes. API, MCP, Agent Skills and CLI come with every plan. An agent can call the AI writer, price a talking actor ad and render it from the same credit balance, or run a workflow template in one call with one spending cap for every step. A person sets its limits: by default 600 credits per job and 2,000 a day.
