I'm Daichi Nagashima, a Japanese software engineer based in Tokyo. I started my career as a physician, but I was drawn to the potential of AI and made the leap to become an AI engineer. Now, as CEO of GENSHI AI, I work at the intersection of healthcare and generative AI. I'm also part of the AI team at the University of Tokyo Hospital.
I'm also a serious photographer. My gear includes a LEICA Q3 43, Fujifilm X-E4 with Voigtlander 23mm F2, and Sony a7III. I also shoot film with cameras like the Carl Zeiss Contax Aria and various Minoltas.
If you're a photographer, you know the frustration: uploading photos to the web or building a blog, only to have compression destroy your images.
Even on Mac, there wasn't a decent app. I had to use separate tools for compression and cropping. On Windows, the situation was even worse — no serious options existed.
As an AI engineer with deep expertise in image processing, I started researching better algorithms in academic papers. That research became Karui.
The name "Karui" means "light" in Japanese. The app itself is lightweight despite being cross-platform, and the compressed photos are both higher quality and smaller than anything else on the market.
I built the software I wanted most. I included every feature I needed, and since most compression tools look outdated, I made sure the design was refined too. Karui is my pursuit of perfection.
