About the creators
Built by real people with one clear idea.
LJ AI began as a personal project created by Lauchlan Johnson. He wanted an assistant that could do more than answer questions—something that could help with everyday work, creativity and connected devices from one place.
After sharing the idea with people close to him, Lauchlan decided to turn it into a public app. His friend Kinttr joined the journey by testing builds, sharing honest feedback and suggesting features and improvements.
LJ AI is their first major published project. It is built with care, shaped by real feedback and supported by the same people behind it. If something is not working or you have an idea, send a support ticket or email the team.
