Wherever a customer asks, KakaoTalk Channel, Naver TalkTalk or the website, it answers from the shop info.
When it does not know, it does not guess. It passes the question to the owner.
Guest challenge
Play the customer and ask the example shop's AI yourself.
Each type of question unlocks a badge.

Today's tally
We write it down before we build
One page on what and why first, then we build only inside that scope.
The AI answers only from data you set
Questions outside the shop info get "I don't know" and go to the owner.
It runs on a free plan
Built to fit the Cloudflare free plan, so a small shop can use it without worrying about cost.
