Mission: an AI platform to learn, practice and get certified in any subject. Two pre-launch products on the way, built on Claude in English, Japanese and Vietnamese, and operated by me in Japan. Join either waitlist at kachinoko.com.
Kachinoko: learn on the time you have
A study planner, first for the CCAR-P exam.
- You enter two things: your exam date and the minutes you have each day.
- You get a daily review plan, short, clear and paced to your date.
- Planned: practice questions written by Claude, with explanations that adapt to your weak topics. Not yet public.
Kakehashi: answer your agents from your phone
A personal tool for one person or a team running several AI agents, such as Claude Code, Codex, Pi.dev, OpenCode or VibeFlow.
- Agents ask: each agent sends its question to one queue instead of waiting on you.
- Most urgent first: what blocks work is at the top.
- You answer from any device, and the agents keep working.
