Closed beta — open now

How to start.

What you can use today is the chat with an AI Otome — OTOME AI — open as an invite-only closed beta. What is planned after it is at the bottom of this page.

01 / AI LEARNING

Learn investing by talking to an AI Otome.

A place to bring a word you do not understand while you still do not understand it. Terms, schemes, the background behind the news, how to size a risk. Start anywhere, and ask the same thing as many times as you like. During the closed beta you can talk with NASU-Nana, who covers US tech stocks and indices. Kawasein Sera, Tsukiyo Ado and Kinnomiya Inori will follow.

    Up to 20 questions a day. The count resets at midnight, Japan time.

Things people actually ask.

02 / COMING LATER

In preparation

Make a call, then see how it went.

How much you have read is a poor measure of what you have learned. Writing down where you think the market goes next, and coming back to it later, is a better one — and that is what we are building.

Not a contest over who was right. A place to keep why you thought what you thought, so you can read it back.

What it covers and when it opens are both undecided. It will be announced on X, note and the blog.

SOBA OTOME provides educational and reference material. It does not give investment advice or trading instructions, does not solicit financial products, does not recommend individual securities, and guarantees no returns. Every investment decision remains yours, and your responsibility.
