Why siblings can look so different
Siblings share parents but not the same genes — each of you inherited a different random half from each side. That's why two siblings can land anywhere from near-twins to barely-alike, and why one of you might favor a grandparent. It's the same shuffle that makes twins not always look identical, explained further in do siblings look alike?.
For laughs, not lab results
This scores how alike two faces look — it isn't a DNA test and can't confirm biological relationships. Enjoy the bragging rights, but don't read anything more into it.
Make it a game
Rank all the siblings from 'most alike' to 'least alike,' or pull in a parent and see who each sibling favors. More ideas in fun ways to compare family photos.
Frequently asked questions
Can AI tell if two people are siblings?
No. It can only score how similar two faces look. Sibling status can't be confirmed from photos — that would require a DNA test.
Why do my sibling and I look so different?
Because you each inherited a different random mix of your parents' genes. Siblings can range from near-identical to quite different, and either of you can favor a grandparent.
Is the sibling report private, and what does it cost?
Selected photos are handled through private AI processing. You can view a limited preview before purchase; the complete report requires a report credit.
