Creative direction without the creative team
Most small brands don't lack tools, they lack direction: what to post, what angle to take and why last week's video didn't work. An AI creative director fills that gap.
Kiryu starts with questions about your product, audience and goal, then comes back with angles to test, a brief, hooks and scripts. It plans a week of posts with a reason for each one. When you're ready it makes the pieces on KreatorFlow (Seedance video, Seedream images, voiceovers, Lip Sync presenters and edits) and reviews the finished video frame by frame before you post it.
What Kiryu handles
Angles to test
Several ways into the same product: problem, transformation, social proof, humour, founder story.
Briefs and scripts
A clear brief, then hooks, scripts, shot lists and on-screen text for each angle.
Content plans
A week or a month of posts, what each one is for and when it goes out.
Ad creative
Ad angles and variations for paid social, written and made in the same place.
Production
Video, images, voice, Lip Sync and edits, set up from the chat with the price shown first.
Quality control
Frame-by-frame reviews with the top three fixes before anything is posted.

Made for organic TikTok, Reels and Shorts
Kiryu is built for the videos people find in their feed, not on a billboard. Everything it writes and makes starts from how short-form is actually watched: a thumb ready to scroll, sound often off, and about three seconds to earn the rest.
- Hooks written for the first three seconds, with the on-screen text and first shot
- Formats that work on short-form right now: skits, before and after, storytime, UGC, series
- Vertical 9:16, captions that sit clear of the app's buttons, and the right length per platform
- Posting plans for a week or a month, with a reason for every post
- Reviews that check where people stop watching and whether your call to action lands

AI creative director questions
What does an AI creative director do?
The same job as a human creative director, for short-form video: decide the angle, write the brief, approve the hooks and script, plan what goes out when, and check the work before it ships. Kiryu does all of that in a chat, and because it runs on KreatorFlow it can also make the video, images and voice.
Who is it for?
Founders, small brands, solo creators and marketing teams who need a steady flow of TikToks, Reels, Shorts and ads but don't have a creative team. Agencies use it to get first drafts and angles fast.
Can it keep to my brand?
Yes. Tell Kiryu your brand, audience, tone and what to avoid once. It remembers that across chats and uses it for every hook, script and visual.
Does it replace a human creative director?
No. It gives you fast options, a clear structure and honest feedback, but the taste and final decisions stay with you. Many teams use it to get from a blank page to three strong options quickly.
Can it make the content too?
Yes. Kiryu can set up Seedance 2.0 and 2.5 video, Seedream images and image edits, Lip Sync talking videos, Voiceovers, music and sound effects, Kitsune motion transfer, Face Swap, Kartoonz cartoons, Cuts, trims, joins, crops, speed, captions and 9:16, Transcripts, speech translation and voice cloning from the same chat. Each action shows its credit price before it runs.
How much does it cost?
You can start free with 15 messages and 1 video review a day. Paid plans include a larger daily Kiryu allowance, Pro and Max modes and every studio tool; anything you make uses credits, as in the studio.
