Hi, I'm rai

I'm an independent developer from Japan building practical open software.

What I work on

VistaUpdater (50k+ views on YouTube) — vistaupdater.net
Restores Windows Update for Windows Vista / Windows 7 after Microsoft discontinued SHA-1 based endpoints. Built for retro PC preservation, lab environments, and careful legacy maintenance — not as a substitute for a supported OS on daily machines.

Deni AI (~600 active users) — multi-model AI chat for everyone
A modern chat app that brings together models from OpenAI, Anthropic, Google, Groq, xAI, and more. The goal is simple: make advanced AI easier to use, without locking people into a single closed garden.

Why sponsor

Your support directly funds:

  • Hosting, domains, and infrastructure
  • Time for maintenance, security fixes, and new features
  • Community support and documentation
  • Keeping both projects sustainable as independent software

Whether you use VistaUpdater on a lab machine, chat with Deni AI every day, or just want more independent tools on the internet — thank you. Every bit helps.
