How weekly hook testing works
Step 1: Brief
Day 0
You send your store link and three competitors. We write hook angles and scripts.
Step 2: Generate
Days 1 to 2
We produce the ads with AI avatars and voices we create. No real person's likeness.
Step 3: Quality check by a human
Day 2
A person reviews every clip for lip sync, hands, text and artifacts. Weak clips get remade.
Step 4: Test
Days 3 to 9
You run the hooks on your ad account, or we help set up the test. Spend stays in your account.
Step 5: Iterate
Every week
We read the results, report cost per trial or signup, and build the next batch from the winners.

FAQ: AI UGC for subscription apps
What is Hookyu?
Hookyu is a done-for-you studio that makes AI UGC video ads for subscription apps and helps you test which opening hook wins on TikTok, Reels and Shorts. You get packs of five vertical ads plus a weekly readout of spend and cost per trial or signup.
How much does AI UGC for subscription apps cost?
A five-hook sample pack is free once per company. Paid Hook Packs start at $250 per pack (five ads). Monthly retainers with about 15 videos and a weekly test report typically run $1,500 to $2,500. Custom scopes are quoted after a brief.
How is Hookyu different from self-serve AI UGC tools?
Tools like Arcads or Creatify are built for teams that generate clips in-house. Hookyu is a managed service: we write hooks, generate AI avatars and voices, review every clip by hand, and deliver a weekly test report so you know which angle to scale.
Do you run TikTok ads for us?
Ad spend stays in your ad account by default. You run the hook test, or we help you structure it. We do not take over billing unless we agree that in a separate contract.
Is it AI?
Yes. The people, voices and scenes are AI-generated. We label ads as AI-generated wherever a platform requires it, and we never use a real person's likeness.
Who owns the videos?
You do. Per our contract, the final videos are yours to run, edit and keep.
Which platforms?
TikTok, Instagram Reels and YouTube Shorts. Everything is 9:16 with captions and safe zones.
What do you need from me?
Your store or app link and three competitors you watch. That is enough for the first pack.
Refunds and revisions?
Each pack includes one revision round. If a clip has a visible defect we remake it. If we miss the agreed brief, we refund that pack.
