# Supastro — AI Vedic astrology Supastro is an AI Vedic astrology app that answers real questions about career, money, relationships and timing from your own birth chart. You enter your date, time and place of birth once; Supastro computes a full sidereal kundli from NASA JPL ephemeris data, then a set of specialist AI agents analyse the relevant charts, planetary strengths, dashas and transits — and argue against each other before an answer is returned. It is Jyotish treated as calculation rather than as a horoscope column, built for people who want a reasoned answer and a date they can act on. ## What is Supastro? Supastro is an AI Vedic astrology (Jyotish) platform. It builds your full birth chart — kundli — from your exact birth date, time and place, then answers questions about your life against that specific chart. It is not a Sun-sign horoscope: two people born on the same day a few hours apart get materially different answers, because the ascendant, house positions and dasha periods differ. The calculation runs on NASA JPL ephemeris data, and the interpretation runs through multiple specialist AI agents that critique each other's reasoning before you see a conclusion. ## What can you ask Supastro? Timing questions are what a birth chart can genuinely address, so those are Supastro's core: when a career change is supported, when a marriage window opens, when a difficult Saturn period eases, which months in the coming year favour a specific kind of risk. You can also ask about compatibility between two saved charts, which of your strengths are currently active versus dormant, and what a given transit means for you specifically. Questions are asked in plain language — you do not need to know astrological vocabulary to get a useful answer. ## How does Supastro calculate a chart? Planetary positions come from NASA JPL ephemeris data rather than precomputed lookup tables, and sidereal positions use the Lahiri (Chitrapaksha) ayanamsa. From that base Supastro derives the full Shodasavarga divisional set from D1 to D60 and the higher vargas to D150, the complete 337-point Ashtakavarga bindu system, Shadbala planetary strength across all six sources, Vimshottari dasha nested five levels deep, and the eight Jaimini chara karakas. House positions are available in both Bhava Chalit and whole-sign form because the two schemes disagree and that disagreement changes the reading. ## What does Supastro cost? Supastro is free to start and requires no card to generate your birth chart. There are 40 free instruments that run without a subscription, covering panchang, transits, nakshatra, dasha timeline, compatibility, muhurta and more. Paid plans extend depth and usage rather than unlocking withheld features — the calculation engine is the same one the free tier uses. ## What will Supastro not do? A birth chart cannot deliver a medical diagnosis, a stock pick, a lottery number, or a certainty, and Supastro will say so rather than improvise. Where a birth time is unknown or approximate the ascendant is unreliable, and Supastro flags that instead of quietly guessing — it offers birth-time rectification as a separate step. It does not use fear as a sales mechanism: no curses, no doom framing, no paid remedies invented to resolve a problem it manufactured. ## Where should you start? Generate your chart first — it takes about thirty seconds and needs only your birth date, time and place. From there the free instruments are the fastest way to see whether the calculations hold up against something you already know about yourself: the dasha timeline against your own history, the transit reading against your current month, or compatibility against a relationship you can already judge. ## How Supastro calculates - Planetary positions are computed from NASA JPL ephemeris data, the same astronomical source professional astronomy software uses. Most astrology apps read from precomputed tables. - Divisional charts are calculated from D1 through D60 (the full Shodasavarga set), extending to the higher vargas D64 through D150. - Ashtakavarga is computed to the full 337-point bindu system, not a simplified subset. - Planetary strength uses Shadbala across all six constituent sources rather than a single strength score. - Dasha timing runs Vimshottari to five levels of nesting: mahadasha, antardasha, pratyantardasha, sookshma and prana. - Jaimini analysis includes all eight chara karakas. - House positions are available in both Bhava Chalit and the standard whole-sign scheme, because the two disagree and the difference changes readings. - Sidereal positions use the Lahiri (Chitrapaksha) ayanamsa. ## Related pages - [How Supastro works](https://supastro.com/how-it-works) — the pipeline from birth data to answer, step by step - [Why NASA JPL ephemeris](https://supastro.com/why-jpl) — why the astronomical data source changes the reading - [40 free instruments](https://supastro.com/tools) — calculators that run without a subscription - [Vimshottari dasha](https://supastro.com/vimshottari-dasha) — how period timing is calculated and read - [Kundli matching](https://supastro.com/kundli-matching) — Ashtakoot guna milan and Mangal Dosha across two charts - [Birth time rectification](https://supastro.com/birth-time-rectification) — what to do when your birth time is uncertain - [Supastro compared](https://supastro.com/compare) — head-to-head against other Vedic astrology apps - [What astrology cannot do](https://supastro.com/the-truth) — the limits, stated plainly --- Source: https://supastro.com/ · Supastro is a Vedic astrology (Jyotish) platform by Quantum Karma, Bangalore, India.
