What is 映え偏差値?
A free service that scores photos, illustrations, and AI-generated images with AI. No login required. It analyzes three dimensions—beauty, quality, and social media appeal—and returns a deviation score, percentile, and ranking, compared separately by image type (Photo / AI Photo / Illustration / AI Illustration / 3DCG).

About "映え偏差値"
What is 映え偏差値 (Bae Hensachi)
映え偏差値 (official name: 映え偏差値 BAE SCORE) is a free service that scores photos, illustrations, and AI-generated images, returning where an image stands as a deviation score, percentile, and ranking position. No login is required — upload an image and the result appears immediately.
Its role is to turn the vague feeling of "I think this photo is good, but how does it look objectively?" into a relative value measured against other submissions.
It breaks "a good image" into three parts and scores each
Rather than judging "is this photogenic" as a single blur, the service splits the evaluation into three axes. A single overall score gives you nothing to act on, but knowing which axis is low tells you what to fix next.
Beauty covers composition, color, and overall impression; quality covers resolution, brightness, and finish; social media appeal covers shareability and eye-catching power. The first two measure completeness as an image, while social media appeal stands on a different axis entirely.
In practice, an image can score high on beauty yet low on social media appeal, or the reverse. Splitting into three axes lets you judge whether an image fits its intended use.

Separating image types is what makes the comparison meaningful
Scoring AI-generated images, hand-drawn illustrations, and real photographs on the same scale would not produce a meaningful comparison. \u6620\u3048\u504f\u5dee\u5024 has you pick an image type at upload — Photo / AI Photo / Illustration / AI Illustration / 3DCG / Not sure — and the rankings are separated by type. "Not sure" is there for cases you cannot classify.
That is also why it uses a deviation score: rather than an absolute point total, it indicates relative position within the pool of submissions of the same type. The percentile display works on the same principle.
As the screen on the left shows, the upload area, visibility setting, and image type all sit on a single screen, and the whole flow completes there without a login step.
How to use
-
Upload an image
JPEG, PNG, or WebP, up to 50MB per image. No account registration or login is needed.
-
Choose a visibility setting
Select from "Participate in ranking (public)," "Only people with the link," or "Fully private." If you do not want to appear in the ranking, choosing private lets you receive only the score.
-
Select the image type
Choose from Photo / AI Photo / Illustration / AI Illustration / 3DCG / Not sure. If you cannot classify it, "Not sure" is fine. Your image is evaluated relative to others of the type you select.
-
Check the result
The deviation score, percentile, and ranking position are shown along with the analysis for each of the three axes.
-
Delete it if you want to
A deletion link is issued when you post. Even without logging in, you can delete your own submission through that link.

FAQ
Q. Do I need to create an account?
No. You can upload and receive a score without logging in.
Q. Can I delete an image after posting it?
Yes, through the deletion link issued when you post. Since it works without a login, you need to keep that link.
Q. Can I get a score without appearing in the rankings?
Yes. Selecting "fully private" for visibility keeps your image out of the rankings while still returning the score.
Q. Can AI-generated images be scored?
Yes. Image types include "AI Photo" and "AI Illustration," which are tallied in rankings separate from real photographs and hand-drawn work.
Q. Does the score change if I post the same image repeatedly?
No. The same image is designed to receive the same score.
How it differs from other image tools
映え偏差値 neither generates nor edits images — it evaluates images you already have. That is where its role diverges from other AI image tools.
| Aspect | 映え偏差値 | Image generation AI | Design tools |
|---|---|---|---|
| Role | Evaluating existing images | Creating images | Editing and laying out images |
| Input | An image you have | A prompt | Assets and templates |
| Output | Deviation score, percentile, three-axis analysis | A generated image | A finished design |
| Price | Free | Typically free tier plus subscription | Typically free tier plus subscription |
| Account | Not required | Required | Required |
On the generation side, Midjourney and ImageFX are representative; on the editing and design side, Canva is. It is often used alongside them to objectively check how a generated image turned out.
