Built for the group chat, not the mandap
Plenty of “compatibility” widgets secretly reuse a romance formula and slap a new heading on top. This one does not. There is no FLAMES walk, no Venus talk, no Destiny-digit gap. The only question is: how much of the alphabet do these two spellings share once you throw away duplicates and punctuation?
That makes it a fair classroom toy. Two people whose names are almost anagrams will score high even if they have never met. Two people named “Om” and “Shreyas” can be inseparable and still land lower because their letter bags barely overlap. Keep the screenshot; leave the verdict.
The Jaccard method, without the jargon
Collect the unique A–Z letters in name A. Do the same for name B. Count how many letters appear in both lists, then divide by how many appear in either list. That fraction is the Jaccard index of the two sets. We map it onto a friendlier band: percentage = round(35 + 60 × that fraction). Zero shared letters still scores 35 so the bar never looks like a failing grade for a spelling accident. Complete identity of letter sets scores 95.
Example shape: names that share two letters out of eight distinct ones across both bags sit at 2/8 = 0.25, which becomes 35 + 15 = 50%. That is arithmetic, not a character assessment.
