A light, fun compatibility score between two names — a playful starting point, not a substitute for full kundli matching.
This scores two names against each other. It is a piece of fun with no basis in either chart, and saying so is not modesty — it is the difference between a toy and a claim. No planetary position is consulted, no birth detail is used, and the number it returns carries exactly the authority of the letters you typed.
If you want a real compatibility reading, Ashtakoota Guna Milan is free on this site: eight kootas scored out of thirty-six from both birth charts, with Mangal, Nadi and Bhakoot dosha checked and the classical exceptions shown rather than hidden. It needs both birth dates, times and places. It will sometimes tell you something you did not want to hear, which is rather the point of using a real method.
No. It is a name-matching amusement. The chart-based method for this question is Ashtakoota Guna Milan, which is free here and uses both people's actual birth details.
No — and we would rather lose the click than imply otherwise. Use the free 36-point matching, and even then read the whole chart rather than the number alone.
