Independent software.
One mission.
Kaiyo Zero is an independent software studio, building tools worth using.
Hi, I'm Chazic.
"I started Kaiyo Zero because I was tired of apps that treat users as a product. Every second app has ads, every third wants your email address, and most of them are bloated with features nobody asked for."
"I wanted to build something different — software that respects the person using it. Simple tools, honestly priced, with nothing hidden and nothing exploitative."
"Kaiyo Notes is the first app. It's the note-taking app I always wanted and couldn't find. More will follow — each one built on the same foundation."
- 1 No ads — in any app, ever
- 2 No selling your data — it doesn't leave your device
- 3 No dark patterns — upgrade prompts are honest and skippable
- 4 No feature bloat — if it doesn't belong, it doesn't ship
- 5 Freemium done right — the free tier is genuinely useful
Kaiyo (海洋)
Kaiyo is the Japanese word for ocean — vast, deep, and always in motion. The wave motif in our logos is inspired by Hokusai's Great Wave, a symbol of both power and precision. We chose it because great software, like the ocean, should feel both effortless and alive.
