A second pair of eyes before you post
Most short videos are lost in the first three seconds, and it's hard to see why when you've watched your own edit fifty times. AI video feedback gives you an outside view: what a viewer actually sees and hears, where the pace sags, which caption is too small or sits under the like button, and whether the point lands.
Kiryu doesn't guess from a description. It watches the video, listens to it and writes a timeline of every shot, caption and line of dialogue, then reviews the video against that timeline with a timestamp on every note. Before you see the review, a second pass checks each factual claim against the timeline and removes anything it can't back up.
How to get feedback on your video
- 1
Upload the video
Drop your video into a Kiryu chat, or pick one from your KreatorFlow library. Say where it's going (TikTok, Reels, Shorts or an ad) and what it's meant to do.
- 2
Kiryu watches it
It looks at the video frame by frame, closest in the first seconds, and listens to the audio, so it knows what's on screen, what's said and when every cut lands.

Get notes and the fixes
You get timestamped notes, the three changes that would help most, and a rewritten opening. Ask Kiryu to make the new version and it sets it up in the same chat.
What Kiryu checks
The hook
The first three seconds: what a viewer sees, reads and hears, and whether they would stop scrolling.
Retention and pacing
Shot lengths, dead spots and the moments attention is likely to drop, segment by segment.
Clarity of the idea
Whether it is obvious what the video is and why someone should keep watching.
Captions and on-screen text
The wording, quoted back to you, plus timing, placement, legibility and safe zones.
Audio
Voice against music, music fit, sound design and silences.
Visual quality
Framing, lighting and visible artefacts.
Call to action
Whether there is one, when it lands and whether it is clear.
Platform fit
Aspect ratio, safe zones and length for TikTok, Reels or Shorts.
What you get back
- Notes on each of the eight checks, with timestamps like 00:02.5
- The top three fixes, in order of impact
- A rewritten opening: on-screen text, first line and first shot
- The timeline of what Kiryu saw, to check any note yourself
- An offer to make the new version with the studio tools
Want to fix it straight away? Kiryu can recut, crop, re-caption or regenerate a shot in the same chat. That workflow is what we call vibe editing.
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 video feedback questions
What does AI video feedback check?
Eight things: the hook, retention and pacing, clarity of the idea, captions and on-screen text, audio, visual quality, call to action, platform fit. Every note points to the moment in the video it's about.
Does it really watch the video, or just read the title?
It watches it. Kiryu samples the video frame by frame (more densely in the opening seconds, where most viewers decide), transcribes what's said and by whom, and builds a timeline of what it saw. You can open that timeline in the chat to check its notes against the video.
Can AI feedback make up things that aren't in my video?
That's the risk with AI reviews, so Kiryu runs a second check: every factual claim in the review is compared with the timeline of what it saw, and anything the timeline doesn't support is corrected or removed before you see it. If something isn't covered, such as a video with no audio, it says so instead of guessing.
Is AI video feedback free?
A verified free account gets 1 video review a day, together with 15 messages. Paid plans include more reviews in their daily Kiryu allowance.
Which platforms is the feedback for?
Short-form vertical video first: TikTok, Instagram Reels and YouTube Shorts, plus ads. Tell Kiryu the platform and it checks the ratio, length and the safe zones where the app's buttons cover your captions.
Can I ask follow-up questions about the review?
Yes, the review is part of a chat. Ask why a note matters, for three more hook ideas, or for a version with a different opening, and Kiryu can make that version with the studio tools.
Does it work on videos I didn't make on KreatorFlow?
Yes. Upload any video file you have the rights to. It doesn't need to be made with KreatorFlow.
