The Cheonmyeongdang saju Telegram bot turns the Korean four pillars tradition into a free saju reading Telegram mini app. Enter your birth date inside Telegram and get your four pillars chart and today's fortune free — no download, no sign-up, no email. If you want to go deeper, a personal reading is available for 50 Telegram Stars, paid safely through Telegram itself.
Telegram mini apps are full applications that run inside a chat window — you never leave Telegram. The Cheonmyeongdang mini app gives you three things:
| Feature | What it is | Cost |
|---|---|---|
| Four pillars chart | Your complete saju chart — year, month, day and hour pillars — calculated from your birth date, with your Day Master and Five Elements balance explained in plain English | Free |
| Today's fortune | A daily reading based on how today's energy interacts with your own chart — a different result each day, personal to your pillars | Free |
| Personal deep reading | A longer interpretation of your chart: element balance, Sip-sin themes, relationships, work and timing, written for your specific pillars | 50 Telegram Stars |
Both are built on the same engine, so your chart is identical in either. The Telegram mini app is the fastest way to get a chart and a daily fortune where you already chat. The sajuapp.app web app adds the larger toolset: compatibility readings, the ten-year daewoon cycle, tarot, and the full library of guides. A natural path: start in Telegram, then open the web app when you want to go deeper than one reading.
Yes. Calculating your four pillars chart and reading today's fortune costs nothing. There is exactly one paid item — the deeper personal reading at 50 Telegram Stars — and it is optional. You can use the free chart and daily fortune indefinitely without paying.
No. Telegram mini apps run inside the Telegram app you already have. Open t.me/sajuapp_bot/saju, tap to launch, and the calculator opens in a window inside your chat — on iOS, Android or Telegram Desktop.
Only your birth date, plus your birth time if you know it. If you do not know your birth hour, the app still builds a meaningful chart from the year, month and day pillars — see the guide to saju without a birth time. No name, phone number or email is required for the free chart.
Telegram Stars are Telegram's in-app currency, bought through Telegram itself. If you choose the deep reading, the mini app shows an invoice for 50 Stars and Telegram processes it in its own payment interface. The free features never ask for Stars.
A saju chart describes temperament, element balance and timing in a vocabulary refined over centuries. It is a structured mirror for reflection — useful in the way a good personality framework is useful — not a prediction machine. No reading, free or paid, can promise outcomes, and this one does not try to. Readings are provided for entertainment and reference purposes.
