Not a contest. An AI is instant, cheap by the minute and sells you nothing; a person reads the room, performs ritual and can be held accountable. Here is which to use when.
Selling one as the replacement for the other is the wrong frame, and we would rather say so than pretend. The question decides.
Both read the same chart. A jyotishi with an ephemeris and this site with the Swiss Ephemeris — given the same birth details and the same ayanamsa — compute the same lagna to the same degree, the same nakshatra, the same dasha dates. The disagreement, when there is one, is about the reading — never the arithmetic, and if it ever is about the arithmetic then one of the two has made a mistake you can find.
That is worth knowing before you pay either of us: take the free chart, and bring it to whoever you consult.
Neither is better across the board. An AI is available instantly, holds the entire chart in view, costs minutes rather than a consultation fee and has no gemstone to sell you. A person reads the room, can decline to answer, performs ritual and can work with you over years. Which matters depends on the question.
For birth time rectification, for anything ritual, for a decision you want a person to be accountable for, and when the question is really about grief or fear rather than the chart.
