A kundli is the Vedic birth chart: the sidereal positions of the nine grahas, the lagna, the houses, and the Vimshottari dasha timeline, traditionally rendered as the North or South Indian diagram. Most online kundli services are accurate but assume you already read the notation — and most ask for an account.
Science of Light computes the full kundli — chart, dashas, yogas, divisional charts through D60, KP layer — with Swiss Ephemeris parity, and then explains it in plain English at whatever depth you want: a no-jargon Soul Book reading, a friendly Novice mode, or the complete classical toolkit with citations for practitioners. North and South Indian chart styles are both available.
It is free with no login, no ads, and no server: your birth details stay on your device, and your chart travels as a private link you control.
Yes — kundli (also janam kundali) is the Hindi term for the Vedic birth chart, cast in the sidereal zodiac.
Different zodiacs. Kundli services use the sidereal zodiac; most Western sites use the tropical. The ~24° difference shifts many placements one sign.
