Studio shows the numbers. Kiryu shows the cause.

YouTube Studio already tells you a lot about a Short: how many people chose to view it instead of swiping away, and where the retention line falls. What it can't tell you is what was on screen at that moment. A YouTube Shorts analyzer fills that gap.

Kiryu watches the Short frame by frame (more densely in the opening seconds), transcribes the speech and reads every caption word for word. Its review is written against that record, so you get "00:00.5: the first frame is a dark fade, nothing to read yet" instead of general advice. A second pass checks every factual claim in the review against what Kiryu saw before you read it.

How to analyze a Short

  1. 1

    Check YouTube Studio first

    Open the Short's analytics and note two things: how many viewers chose to view versus swiped away, and where the retention line falls. That tells you which part of the Short to ask about.

  2. 2

    Upload the Short to Kiryu

    Drop the video file into a Kiryu chat and say it's a YouTube Short. Add what Studio showed you, for example "most people swipe away" or "retention falls at 0:12".

  3. 3

    Get the notes and the fixes

    Kiryu answers with timestamped notes on each check, the three fixes that would help most and a rewritten opening, and can make the edit in the same chat.

Match what Studio shows to what Kiryu checks

What Studio showsWhat it usually meansWhere Kiryu looks
Most viewers swipe awayThe first frame and first second didn't earn the view. Shorts viewers decide even faster than they read.The hook check, where Kiryu samples frames most densely, plus the first line of speech.
Viewed, but retention slidesThe idea is unclear or the middle has no new information. Viewers stay to find out what it is, then leave.Clarity of the idea, and retention and pacing segment by segment.
A sharp drop at one momentSomething specific happened: a long pause, a cut to a weaker shot, a caption that's hard to read.The timeline at that second: what was on screen, said and heard.
Fine numbers, no subscribersNo reason to come back: no series, no ask, no link to a longer video.Call to action: whether there is one, when it lands and if it's clear.

The eight 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.

Shorts habits that help

  • Plan the loop. Shorts replay automatically. An ending that runs straight back into the opening line gets watched twice instead of swiped.
  • Write a title people would search. Shorts show up in YouTube search, and the title is part of what's shown in the feed. Name the topic plainly.
  • Link a longer video. If you make long videos too, a Short can link to one. A Short that sets up a question the long video answers gives viewers a reason to click.
  • Mind music on longer Shorts. YouTube has said Shorts over a minute with a Content ID claim can be blocked, so check the music before posting a longer one.
  • Keep text clear of the bottom and right. The title, channel name and buttons sit there. Kiryu flags text in those areas.

What you get back

  • Timestamped notes on all eight checks
  • The three fixes that would help most
  • A rewritten opening: on-screen text, first line and first shot
  • The timeline of what Kiryu saw, to check any note
  • Edits made from the chat: trims, cuts, captions, 9:16 crops

YouTube Shorts analyzer questions

What does a YouTube Shorts analyzer check?

Kiryu checks the hook, retention and pacing, clarity of the idea, captions and on-screen text, audio, visual quality, call to action, platform fit, with a timestamp on every note. It also gives you the three fixes that would help most and a rewritten opening.

Why do people swipe away from my Shorts?

Usually because nothing in the first second tells them what they'll get: a slow fade in, a greeting, a logo, or text that's too small to read in time. Upload the Short and Kiryu points to the exact frame and line that's costing you, then rewrites the opening.

Does Kiryu connect to my YouTube channel?

No. It reviews the video file you upload and can't see your YouTube Studio numbers. Tell it what Studio shows and it will look at those moments.

Can it analyze long YouTube videos too?

It's built for short-form. Very long videos are only analysed up to a length limit, so for a long upload, review the opening or a section you're unsure about as its own clip.

Is the Shorts analyzer free?

A verified free account gets 1 free video review a day, together with 15 chat messages. Paid plans include more reviews in their daily Kiryu allowance.

Can I use the same video for Shorts, TikTok and Reels?

Often, yes, but check each version. The buttons and captions sit in slightly different places on each app, and a watermark from one app is a bad look on another. Tell Kiryu the platform for each upload and it checks the fit for that one.
