Company Profile
About us
JC H&E is a general incorporated association (ippan shadan hojin) founded in Osaka in 2017. Today, AI and software are at the center of our work. In October 2026, we released our first product, ConvoArk, a Chrome extension for saving AI conversations.
We will keep delivering tools you can trust in the age of AI, one at a time and with care.
How we work
Be honest
What we can and cannot do, what is free and what is paid: we tell you the important things up front.
Treat information with care
We do not collect more information than we need. ConvoArk, too, is designed not to send conversation text to external servers.
Start small, keep improving
We listen to the people who use our products and make them a little better, step by step.
