What it is

Website Summary

It calls itself “BLEND | 校務支援システム”.

In its own wordsBLEND | 校務支援システム先生の校務をもっと簡単に、スマートに

The page doesn’t show enough to say what kind of site it is (a shop, a blog, an app…).

More about it: Wikidata, profiles, AI use, page facts

AI use

All crawlers: asks every crawler without rules of its own to stay away, AI ones included.

Is this wrong? Report it

What its robots.txt and robots tags ask of AI crawlers. Each crawler chooses whether to follow it.

Site name: Not given
Language: Japanese (ja)
What it tells search engines: None

Read from what the page says about itself; we haven’t checked whether it’s true.

Built with AI?

AI Website Detector

No AI builder traces found.

Coding tools such as Cursor leave no traces, so this doesn’t mean a person made it.

AI traces: None found

How we know

AI site builders leave traces in the sites they make. We look for the traces of 53 of them and show every match with the line it came from, so you can check it yourself.

We test this on 2,275 sites whose makers we know, and publish what we get wrong.
