Small software, made carefully.
Yorusei is a one-person studio. We build tools that work without an account, without a subscription to your own data, and without needing to be online — software that quietly does its job, then gets out of the way.
What we make
Seya
Read & Listen
An offline ebook reader that narrates your books aloud, on your device. Import the EPUB, PDF, TXT or Markdown files you already own, and listen anywhere with the screen off. Your library never leaves your phone.

How we work
- Local first. If a feature can run on your device, it runs on your device — so it works offline, it's fast, and it doesn't need our servers to keep working.
- No accounts unless they earn their place. We won't ask for your name or email to let you use something you've already paid for.
- Honest pricing. Buy it once or subscribe, but no dark patterns, no fake countdowns, and no charging you for something that doesn't work.
- Small on purpose. One person, a few products, and enough attention to answer your email personally.
