Horoscho Chart (toolbox.horoschola.jp) is free for everyone. AI Readings are available as an optional paid subscription.
Chart creation — Free
No account, no login, no fees.
As we restart the app on its way to an AI-ready future, we have opened it up so more people can use it.
AI Readings (paid subscription)
From handwriting to desktop software — and now to AI. Based on your chart, the AI writes a reading, and you can keep asking follow-up questions in conversation. Everything runs from a single button, so the prompt is never exposed.
A single in-person or phone reading often costs far more than a month of AI Readings. For the price of one traditional session, you can consult the AI almost every day.

Pro

- One-button readings — the prompt is never exposed

You can always see where your subscription stands
Once you subscribe, a bar like this appears at the top of the AI Reading screen. It shows your plan, how many readings are left in the current period, and when it renews.
This is what you actually see on screen (sample). The colour changes as you approach the limit.
You should never have to wonder whether your subscription went through. Cancelling or changing your card is also one click away, from the link on the right.
What is sent when you use AI Readings
Readings are generated with Google’s Gemini API. When you press the AI Reading button, your chart data (birth date, time and place, and the calculated positions) and anything you write in the “on your mind” field are sent to it through our own server. Your name is not sent unless you switch that option on. Nothing is sent until you press the button, and the charts you save stay in your own browser. See our Privacy Policy for details.
How it works
- Open the app. Go to toolbox.horoschola.jp/app/. No login required.
