Will it know how my region does this, or will I get a generic version?

It knows how your region does it — Bengali Saraswati Puja is not Tamil Bommai Kolu, and Saath does not standardise across regions.

Every occasion is read through a ladder: your fine community first, then your regional tradition, then the pan-Hindu form, then an honest fallback. Picking your community makes the page more specific, never thinner — everything you would have read without picking one is still there underneath.

Where your exact lineage is not curated yet, Saath says so honestly instead of dressing a generic version as yours. A regional answer is a real answer, not a degraded one.
