Closed beta — open now
Investing basics,
with AI.
You want to learn about investing, but you are not sure what to ask first. SOBA OTOME is a place to work through those questions — NISA, regular contributions, the headlines you half understand — one conversation at a time.
Free, invite code required
What OTOME AI does.
OTOME AI is the chat itself — an AI Otome you can think out loud with. It runs as an invite-only closed beta, with NASU-Nana as the one you talk to for now.
The screen below is a demo, written the way Nana actually talks.
A demo, for learning and reference. It does not give investment advice or trading instructions.
What you can ask about
- NISA
- Regular contributions
- US equities and indices
- Currencies and the yen
- Crypto assets
- Gold and commodities
- Reading the news
- Thinking about risk
SOBA OTOME ACADEMY
Nobody gets left behind at the word they did not know.
The Academy is where the learning lives. Alongside the chat there are ways in for reading, for watching, and for checking what actually stuck.

If investing looks hard, that is not your fault.
Most writing about investing is written for people who already understand it. One term gets explained with another, and by the end you have forgotten what you came to ask. SOBA OTOME exists to stop at that point and stay with it until it makes sense.
- You do not know where to start
- What you read never quite connects
- The questions feel embarrassing to ask
All three are fine things to say here. They are the place to start, not the thing to get past.
Four AI Otome. Four markets.
Each of the four AI Otome covers a different market. Only NASU-Nana is available to talk to during the closed beta; the others appear in the manga and the written material.
Bright and easy to talk to. The way in.
Calm, methodical, good at untangling things.
A night owl with a quick tempo, on the crypto beat.
Gentle company, with both feet on the ground.
Why it is safe to ask here.
- 01
No financial products are sold, and no securities are recommended.
- 02
Nobody acts surprised at what you do not know yet.
- 03
One theme at a time, checked as you go.
SOBA OTOME provides educational and reference material about investing. It does not provide investment advice, trading instructions, solicitation of financial products, recommendations of individual securities, or any guarantee of returns.
Every investment decision remains yours, and your responsibility.
A few things worth knowing before you start.
Only the questions people actually ask first. Limits, cost, and why none of this is investment advice are covered in full on the FAQ page.
It runs as an invite-only closed beta. You need an account and a confirmed invite code, and there is a daily limit on questions. For now the one you talk to is NASU-Nana, who covers US tech stocks and indices; the other three follow later. Codes are free: follow @sobaotome on X and send a DM, and we will reply with one.
