Kiryū for ads
The AI ad generator that starts with the angle
Most ads fail on the idea, not the edit. Kiryu finds the angle, writes the hooks and scripts, makes the video ad with Seedance, adds the voice, music and captions, then reviews the cut before you spend a cent on it.
- Made for TikTok, Reels and Shorts
- Angles, hooks and scripts
- Seedance 2.0 and 2.5 video

From brief to ready-to-run ad in one chat
An AI ad generator should save you more than editing time. The expensive part of an ad is the guess: which angle, which hook, which first second. Kiryu works on that first, the way a performance creative team would, and only then makes the ad.
Everything happens in one conversation. Kiryu writes the angles and scripts, sets up the visuals with Seedance and Seedream, makes a presenter talk with Lip Sync, adds a voiceover and music, cuts to length, crops to 9:16 and captions it. When the ad is done, it watches it frame by frame and tells you what to fix, using the same review as AI video feedback.
How to make a video ad with Kiryu
- 1
Brief it like an agency
Tell Kiryu the product, who it's for and where the ad runs (TikTok, Reels, Shorts or Meta). Add product photos, your logo or an old ad that worked.
- 2
Pick the angles
Kiryu suggests several angles (problem and fix, before and after, social proof, founder story, humour) with a hook and a script for each. Keep the ones you like.
- 3
Make the variations
Kiryu sets up the product shots and clips with Seedance and Seedream, a talking presenter with Lip Sync, the voiceover, music, cuts, 9:16 and captions. Each step shows its price first.

Review before you spend
Send the finished ad back and Kiryu watches it frame by frame: is the hook strong, is the product clear, does the call to action land? Fix it before it costs you ad budget.
Ads you can make
Product showcase
Your product photo becomes a cinematic clip: slow push-ins, light, texture, the logo at the end.
UGC-style talking ads
A presenter from a photo you have the rights to, speaking a script Kiryu wrote, with Lip Sync.
Before and after
Two clear states and a hard cut, the format that sells transformations.
Launch teasers
Short, mysterious openers that build up to the reveal.
Offer and sale ads
The offer on screen in the first second, with the deadline and a clear call to action.

Seedream images and edits for feed, story and display placements.

AI ad generator questions
What is an AI ad generator?
A tool that turns a product and a brief into ready-to-run ad creative. Most generators start from a template. Kiryu starts with the strategy: the angle and the hook, then the script, then the video, images and voice, and finally a review of the finished ad.
What kinds of ads can I make?
Short video ads for TikTok, Instagram Reels, YouTube Shorts and Meta: product showcases, UGC-style talking ads, before-and-after, launch teasers, explainers and offer ads, plus still images for static placements.
Can it make UGC-style ads with a person talking?
Yes, from a photo you have the rights to (or an AI-generated person). Kiryu writes the script, makes the voice and uses Lip Sync to make the person say it. You must be the person in the photo or have their permission.
Can I make several variations to test?
Yes. Ask for different hooks, angles, openings or lengths and Kiryu sets up each version. Testing several hooks on the same product is one of the most common requests.
Which models make the ad video?
Video is made with ByteDance's Seedance 2.0 and Seedance 2.5 and images with Seedream. KreatorFlow is an official partner of BytePlus, a ByteDance company.
How much does an AI ad cost to make?
Planning, hooks and scripts are part of the Kiryu allowance (free accounts get 15 messages and 1 video review a day). The ad itself uses credits at the normal studio price, shown before anything runs.
Can I use the ads commercially?
Yes, ads you make on a paid plan are yours to run, as long as you have the rights to what you upload (product photos, logos, people, music) and the ad follows the platform's ad rules.
