Make rigorous Vedic astrology effortless to practise.
For too long, accurate jyotiṣa meant juggling ephemeris tables, scattered tools, and hand calculation. Joishi brings the whole craft into one disciplined workspace — so the astrologer can spend their time on interpretation, not arithmetic.
The whole craft, computed.
Every number below is what the engine actually ships — not a roadmap.
Charts and vargas
D1 through D150, 22 house systems and 47 ayanāṁśas. Positions come from Swiss Ephemeris, with a Sūrya-Siddhānta engine beside it when you want the classical reckoning.
Eighteen daśā systems
Viṁśottarī, Aṣṭottarī, Yoginī, Kālachakra, Chara, Nārāyaṇa, Shoola and more — each expanded to whatever depth you need, with balances computed to the second.
565 yogas, 51 doṣas
Every rule carries a citation to its classical source. No rule enters the engine without one, and every doṣa names its remedies.
Pañchāṅga and muhūrta
Tithi, nakṣatra, yoga, karaṇa and vāra for any moment, with festivals, holidays and Bikram Sambat ↔ Gregorian conversion the Nepali calendar can be trusted on.
Milan, praśna, KP and more
Aṣṭakūṭa matching, praśna, birth-time rectification, nāmakaraṇa, numerology, Lāl Kitāb and pañcha-pakṣī — the applied techniques a working practice actually reaches for.
Four languages, two numeral systems
Sanskrit, Nepali, Hindi and English throughout — every graha, rāśi, nakṣatra and yoga named in all four, with Devanagari or Arabic numerals as you prefer.
Built on a few firm principles.
Accuracy first
Every position is computed with Swiss Ephemeris and re-validated on the backend. No approximations, no drift.
Faithful to śāstra
Defaults follow classical authorities — Parāśara, B.V. Raman, JHora — while every knob remains yours to override.
Made for practitioners
Charts, dashās, yogas, doshas, muhūrta and milana in one place, in your language and numeral system.
Clear, not cluttered
A calm, focused interface that surfaces what matters and gets out of the way of the reading.
