Prompts for UGC Ads: Briefs, Hooks, and Script Review

User-generated content ads work when they feel like genuine creator content rather than polished brand advertising. AI prompts can help you write briefs that reflect a specific product and audience, generate hook options for testing, and review scripts for claims, brand voice, and FTC compliance. Tools like fenbs keep the approved brand decisions and reusable prompts together, so every new creative brief starts from the same agreed foundation.

The templates below cover the main tasks in a UGC ad workflow: writing a creator brief, generating hook variations, reviewing a script for brand voice, and checking a script before approval. Each includes the fields to fill in and a note on what a good response looks like.

What a UGC ad prompt needs

A UGC ad prompt without product and audience context produces generic scripts that sound like every other creator ad. Before you send any UGC prompt, include these details. The more specific they are, the more useful the output.

• The product: what it does, who it is for, and the one claim you most want the ad to land.
• The platform: TikTok, Instagram Reels, YouTube Shorts, or other, since format and length differ.
• The target audience: who should stop scrolling and why this product matters to them.
• The brand voice: the tone the creator should sound like, including any words or claims to avoid.
• Approved decisions: product claims already reviewed, rejected angles, and standing compliance rules.

Prompts for a creator brief

A creator brief that is too vague gives creators too much freedom; one that is too detailed suppresses the authentic feel that makes UGC ads perform. This prompt produces a brief that sets the goal and the constraints clearly while leaving room for a creator's natural voice.

Write a UGC creator brief for [product name].

Product: [what it does and who it is for]
Platform: [TikTok / Instagram Reels / YouTube Shorts]
Target audience: [describe who should stop scrolling]
Key claim: [the one thing you want the viewer to believe after watching]
Brand voice: [how the creator should sound, e.g. casual and direct, friendly expert]
Avoid: [claims, topics, or angles the creator must not use]

Your creator brief should include:
- A clear hook goal (what the first 3 seconds must do)
- 3-5 bullet points of product context the creator can draw from
- A specific call to action
- Any claims the creator must not make

Prompts for hook variations

The hook is the most important creative decision in a short-form ad. A strong hook stops the scroll; a weak one means the rest of the script does not matter. Use this prompt to generate multiple hook options for a creative brief, then test two or three before committing to a full script.

Generate 6 UGC ad hook options for [product name] on [platform].

Target audience: [who should stop scrolling]
Key claim: [what the ad should land]
Brand voice: [how the creator should sound]
Avoid: [anything off-limits]

For each hook:
- Write the first 1-2 sentences the creator would say
- Label the hook type (question / bold claim / relatable problem / surprising fact / personal story)
- Note which type of audience it is most likely to stop

Do not repeat the same structure in consecutive options.

Prompts for brand voice review

A brand voice review checks whether a creator's script sounds consistent with how the brand wants to present itself on the platform. This prompt works best when you include the approved voice guidelines rather than asking the model to infer them from the script itself.

Review this UGC script for brand voice.

Approved voice: [describe the tone, the words the brand uses, and the ones it avoids]
Product: [what the ad is selling]

Script:
[paste the script]

For each issue:
- Quote the specific line
- Describe how it departs from the approved voice
- Suggest an alternative phrasing that keeps the creator feel

Note any line that is on-brand and should not be changed.

Prompts for pre-approval script review

Before a UGC script is approved for production, it should pass a review for two things: accuracy of product claims and FTC compliance. Both are the brand's responsibility even when a creator writes the script. A pre-approval review prompt makes this check consistent across every script in a campaign.

Review this UGC ad script before approval.

Product: [what the ad is selling]
Approved claims: [list the claims that have been verified]
Platform: [where the ad will run]

Script:
[paste the script]

Check for:
1. Any claim not on the approved list (flag each one)
2. Any superlative (best, fastest, only) that is not verified
3. Any statement that requires a disclosure under FTC guidelines
4. Any instruction that could be misread as a personal endorsement without a clear disclosure

For each issue, describe what the problem is and suggest how to fix it.

Keeping approved briefs and decisions between campaigns

UGC campaigns involve many rounds of brief, script, and review. The decisions that come out of each round, about what to claim, which hooks performed, and which voices resonated with the audience, are worth keeping for the next campaign. When those decisions only exist in a Slack thread or a shared doc, the next creative brief has to rediscover them. Writing them into a shared record means the next brief starts from what worked, not from scratch.

After each campaign, record the hooks that performed, the claims that were rejected and why, and any compliance decisions that should apply to all future briefs for this product. Those records become the standing decisions a connected assistant reads before the next creative brief.

A compliance decision is especially worth recording carefully. If a particular type of claim requires a disclosure on a specific platform, or if a product claim needs legal approval before it can appear in a script, that rule should be available to every assistant reviewing every new script rather than something a team member must catch from memory. A missed compliance step creates rework after a script is approved; a rule that a connected assistant reads before each review prevents the problem at the source. Record compliance rules as standing decisions so they apply to every future campaign for that product, not just the one where the issue first appeared.

How to do this with fenbs

1. Create a free account and add a project for the UGC campaign or brand.
2. Write the approved product claims, brand voice rules, and compliance decisions into Decisions and rules.
3. Save your most useful brief, hook, and review prompts in Skills and prompts.
4. Connect your assistant over MCP from Integrations so it reads the approved decisions before each new brief.
5. After each campaign, add the hooks that performed and update any claim or compliance decisions that changed.

fenbs does not submit scripts for FTC review, connect to advertising platforms, or generate images. It keeps the decisions, compliance rules, and prompts your creative workflow depends on, so each new campaign brief starts from the same approved foundation.
